It’s that time of year again, it’s getting warmer out, days are getting longer (assuming you’re in the northern hemisphere), and we get new software to play with. Autodesk has just released a whole bunch of new software, including Civil 3D. Want to know what’s new? Well, just keep reading.

If I know of an issue with one of the new features, I’ll put in a GOTCHA so watch out for those.
For each feature, I’ll also include a Workflow Idea. These will give you an idea on how to leverage the new feature in your workflows. If you have other ideas, let us know in the comments.


Bad News – New File Format

First off, there is some bad news. AutoCAD 2018 introduced a new drawing format which means Civil 3D is not backwards compatible. This honestly comes as a surprise to me, not that they made a new version, but that they kept the prior version for so long. For those of you fairly new to the AutoCAD/Civil 3D world, new drawing versions typically came out every third release or so. The last version of AutoCAD that had a drawing format change was 2013.


Civil 3D 2018 is built on the AutoCAD 2018 file format

Civil 3D on the other hand would have a new object format every single version. We never had any options of backwards compatibility. In 2014, that changed. You could save a Civil 3D 2016 version back to 2013, 2014, or 2015. 2017 saw a new object format which made Civil 3D not backwards compatible and 2018 has both a new drawing format and a new object format so it’s double not backwards compatible.

The reason I bring this up, if one person on the project team decides to upgrade to Civil 3D 2018, the entire project team will need to upgrade. Also, if you install 2018 to test out some of the new features, don’t do it on an active project.

Now let’s get into the good stuff. What’s awesome about the 2018 release?

Offset Profiles

We’ve had Offset Alignments for a while now. You know, create an Offset Alignment, adjust the centerline alignment and the Offset Alignments adjust too. You could then create profiles on those Offset Alignments (say for example to have a 2% cross slope) but if you change the offset value, the profile is no longer at 2%. Likewise, if the centerline profile changes, you’ll need to go manually change the profiles to maintain that 2% cross slope. Well, NO MORE! Offset Profiles will do that for you!

When you create the offset alignment, you’ll see an option to also create offset profiles. You simply put in the desired cross slope and when it creates the alignment, the alignment will have a profile that’s dynamic to the parent profile. Change the parent profile, the offset profile changes. If the parent profile has vertical curves, the offset profile will also have vertical curves.


Create Offset Profiles when you create Offset Alignments

I’m not exactly sure how the offset profile vertical curves are calculated but they always seem to be there. A possible issue is if you have a vertical curve that is part way in a horizontal curve. If you offset that profile at a 2% cross slope, the resulting profile should not have a parabolic curve. If it does have a parabolic curve, then it’s not a true 2% cross slope. In other words, verify you get the results you want!

If you want to edit the offset parameters, select the offset alignment and choose, “Offset Profile Parameters” on the ribbon. This will bring up a dialog box that you can go edit those parameters as well as add transitions to the offset profile.

For example, perhaps you need a 2% cross slope for the first 200’ of the alignment and then over the course of 50’ you want to transition to a 4% cross slope and then maintain that to the end. In the Offset Parameters tab of the offset profiles properties, you can simply add in additional cross slope regions.


Edit Offset Profiles

There seems to be an issue with the slope transitions if the parent profile has a PVI within the transition region. Hopefully this will be fixed soon. I would recommend everyone creating a support request for this so we can get it fixed quickly.

Workflow Ideas
So, how can you use this tool to improve your productivity? Just the other day, I had a client ask me how to apply superelevation to an alignment on a trail so he could control the cross slope of the trail (he didn’t want it to slope into the hill as it switched back and forth down the hillside). Using these tools, you can simply create those offset profiles, add in the cross slope regions, and target your lane to the alignment and profile and you’re done. Need to adjust the cross fall for a specific region? Just adjust the cross slope region on the offset profile!

Connected Alignment

Connected alignments are basically an alignment/profile filet. Have two intersecting alignments that you want to put another alignment curved between them yet always tangent to them? Well, this is the tool you want. Simply select the two alignments, pick in the quadrant you want the connected alignment, specify a few values, and you have the connected alignment. One of the options when creating the connected alignment is to create a connected profile as well. The profile will match the elevations of the parent profiles where the two coincide and then transition to match the other profile at the other end.


Choosing the Quadrant for the Connected Alignment


Options When Creating Connected Alignments


Connected Alignment with Profile


 The two alignments that you want to create a Connected Alignment between must intersect each other. In certain situations, where you might have a non-perpendicular T intersection, the two offset alignments might not intersect each other. In this case, you won’t be able to create a Connected Alignment between them.


Unable to Create Connected Alignments Here

Workflow Ideas
A long long time ago, Autodesk introduced the ability to automate intersection design in Civil 3D however, it only worked well for extremely simple intersections. If things get complex, you’ll need to manually create the intersection. In that case, these tools are ideal!

Extracted Featurelines as Baselines

We’ve been able to extract featurelines from a corridor for quite a while now. Last year, you could also use a featureline as a baseline in a corridor but what you couldn’t do is extract a featureline from a corridor and then add it back into the SAME corridor as a baseline.

In 2018, that limitation has been removed. Extract a featureline and simply add it back into the same corridor as a baseline.


On the left, a single baseline                                                                           On the right, two baselines, one the centerline, one extracted edge of asphalt

Workflow Ideas
One of the issues I’ve seen with corridor modeling is in the area of lane widening. If I have a lane that widens out and has a sidewalk, if I use one assembly, the width of the sidewalk is calculated relative to the baseline, not the edge of the road. In a case like this, you’ll end up with a sidewalk that isn’t as wide (relative to the edge of road) as it should be. So what do you do? Extract the featureline from the edge of the road and add it back as a baseline to the corridor. To that, attach an assembly that contains the curb, walk, and daylight (or whatever subs you are using) and you’re done!

Corridor Bowtie Cleanup Optional

Introduced into Civil 3D 2017, corridors will now cleanup those nasty bowties for you automatically (in certain instances). Now, in 2018, you can choose whether or not Civil 3D will clean those up for you. On the Settings tab of the Toolspace, right click on Corridor and go into the feature settings. In the feature settings you’ll see new options for the bowtie options. You can choose if you want them to clean up the Tangent-Tangent situations or the Tangent-Arc (and Arc-Tangent) situations independently. Oh, and by the way, IT CLEANS UP TANGENT-ARC INTERSECTIONS NOW!!!!!


Bowtie Cleanup Option

Workflow Ideas
I’m not exactly sure why you would want to turn this off but apparently there were people asking for it and so Autodesk included it as an option. I’m all down with options so I’m not going to complain, I just can’t think of a situation where I would want to turn this off. If you can think of one, please leave me a comment.

Daylight Bowties

The bowtie cleanup, as introduced in 2017, was a huge step forward but it wasn’t quite complete. It only worked between two tangents (straight lines) and only worked for links that had a constant width. In other words, the daylighting didn’t clean up. In 2018, they have given you a tool that cleans it up for you. You simply select the alignment piece before the cleanup and the alignment piece after the cleanup and then pick the point you want them to cleanup to. There’s also a tool to remove the cleanup if you want to change it up.


If the design changes, you’ll have to remove the cleanup and reapply it. The tool will continue to cleanup to the same location even if, after the design change, it’s no longer needed.

Workflow Ideas
I kind of think this one is a no brainer. We’ve all done designs where the inside corners of our corridors didn’t work and we would have to extract featurelines and use the grading tools or manually grade in that area. No more, just use the bowtie cleanup tool and you’re done!

Featureline Elevations Relative to a Surface

Featurelines – I love featurelines. Their ability to adjust with other featurelines is just amazing! New in 2018, you can set featurelines to be dynamic to a surface. If the surface changes, the featureline changes! When you create a featureline from objects or assign elevations to it (either through the command or the Elevation Editor), you can choose a surface as well as the relative elevation that you want them to be relative too. You can also adjust the relative elevation for each individual vertex of the featureline.


Create Featurelines from Objects


Elevation Editor

Not a serious gotcha here but, I think you should be aware, a featureline can only reference one surface. If you need a featureline to be relative to two different surfaces, you’ll need to split it into multiple featurelines.

Workflow Ideas
I’m really excited about this one. The area I see it being used really well is for ADA ramps. You know the front of the ram needs to be 6” below the sidewalk and the back of the ramp needs to be at the top of the sidewalk. Create your featurelines that represent the ramp, set the relative elevations, create a surface from it  (I’m not sure if I would do one surface per ramp or put them all in the same surface with multiple boundaries, I’ll have to do some testing on it), and then past both the original surface and the ramp surface into a new surface. If the design of the sidewalk changes, the ramp immediately updates too (just double check to make sure it still meets the requirements).


If you’ve ever worked with sections, you know that what Civil 3D produces is typically not enough for constructions. The sections need additional annotation, blocks, and linework. The problem is, if you move the section views, or if the section views get rearranged automatically, the Autocad objects don’t move with the views, until now. Section Views now have a buffer property. Any AutoCAD objects within the buffer will move with the section view.


Section View Buffer

If you adjust the buffer around a section view to include new objects or exclude existing objects, the objects won’t know the buffer has changed until they (the objects) have been edited. Just do a move from 0,0,0 to 0,0,0 and they will re-identify with being inside or outside the buffer.

You can also add new Section Views to a View Group. In the past, if you needed to add a new sample line in between two sample lines, you would have to either manually update the section views to account for the new view or delete them all and recreate them. In 2018, you can simply create the section view and then add it into an existing view group.


Move to Section View Group

Workflow Ideas
For those of you that do roadway design, this one is huge! It doesn’t really create any new workflows, it just greatly simplifies the ones we already have. Need to add a cross section for a new culvert that wasn’t originally planned? Create the sample line, create the view, and add it to the view group. When the layout of the section views updates, any AutoCAD objects in the views will move with the view.

Plan-Plan and Profile-Profile

The plan production tools have been out for ages now and have been pretty much untouched, until now. In 2018 you can now create Plan-Plan sheets and Profile-Profile sheets. The process is pretty much the same, the only difference is in the template that you use to create the sheets. In the template, create the two (or however many you need)  viewports and in the properties, set them to the correct type (i.e. plan or profile), and then give them the correct order. The viewports have a new property called “Viewport Order”. The viewport you want to use first will have the Viewport Order=1, the second will have the Viewport Order=2, etc.


Plan-Plan Production showing the properties of the lower viewport

The viewports need to have the same dimensions (at least as far as the length of the viewport goes). I tried creating a template with one long viewport and then under that a shorter viewport and it failed. The length of the profile views was calculated using the shorter viewport. I haven’t tested it much but it’s something to be aware of.

Workflow Ideas
I haven’t really come up with any new workflow ideas for this one. Like the section view improvements, it just greatly simplifies the ones we have. In the past, I would create a viewport that was twice as long as I needed and then manually copy it and crop it in order to get the Plan-Plan or Profile-Profile. This just makes the process much easier.


So, what do you think? Which of these are you most excited about? Which one do you think will improve your processes the most? Was there something I missed? I would love to hear your thoughts about the new release. Just leave a comment and let the world know!


<note: In Civil 3D 2018.1, there are some new system variables that deal with these glyphs so go install it now! Just start typing “labelover…” and the autocomplete will finish it off for you>

So, you’ve downloaded Civil 3D 2017 Service Pack 1 to fix those pesky issues. Which issues? These issues. Great, so you close out of Civil 3D, install the service pack, and the next time you’re in your drawing, you notice a whole bunch of warning symbols!


Glyphs Glyphs Everywhere!

What are these things? Well, they are a new feature that was added to Civil 3D 2017 in Service Pack 1. They let you know when a label has a text override. If you hold your mouse over the glyph, it will tell you what it’s there for.


Tooltip when hovering over glyph

Just like the other warning symbols in Civil 3D, when the drawing is regened (run the REGEN command), the glyphs will always go back to a certain percentage of the screen size (I’m not exactly sure what that is and I don’t have a ruler handy to do the calculations).

I can see these symbols pretty much taking over a drawing so, how do you turn them off? Well, there are two ways:
1) Don’t override the text in your labels. I didn’t say they were both GOOD ways.
2) Turn off all the symbols like this in your drawing. I didn’t say either way were GOOD ways!

Yup, if you want them turned off, you have to disable the display of ALL of these warning symbols (Pressure Network Design Checks, Alignment Tangency Checks, Alignment Design Criteria Violations, Profile Horizontal Changes, etc.). To do this go into your AutoCAD OPTIONS and on the AEC Editor tab you’ll see a section called “Solution Tips” (these symbols are called “Solutions Tips” apparently). The two radio buttons allow you to control if you see the tips when drafting (i.e. in your drawing) and when your plot.


Solutions Tips

I suppose the other option is to simply not install Service Pack 1. If you aren’t having any of the issues it says it fixes, and you don’t want these obnoxious symbols all over your drawing, I don’t see any super compelling reason to install it.

What do you think? Do you like the symbols? Do you hate them? Personally, I’ll give them a try. I always recommend to people that when Autodesk does something new to the software, give it a month. If after a month you don’t like it, then go back to the way it was. Now, if I could only figure out how to go back without uninstalling the service pack…


It’s an exciting time of year for all of us Civil Software Geeks, new software is coming out and we get to see the new and exciting things in the latest release. If you haven’t seen it yet, check out my recap of What’s New in InfraWorks 2016.1. I just downloaded the latest release of Civil 3D 2016 and there are several things that are new. Here are the things in this release and the bold ones are the ones I’ll be discussing:

  • Manage data shortcuts to repair broken shortcuts and replace DWG objects
  • Display vault project objects that exist in subfolders within object type
  • Create data references to objects that exist in different vault projects
  • Import and export IFC (Industry Foundation Class) files
  • Select alignments by layer to be used as width and targets
  • Control the direction of sections in section views
  • Subbassembly Composer loop geometry support
  • Create exclusionary catchments
  • Crossing pipe and pressure pipe profile view labels
  • Pressure pipe labels in section views
  • Import Bridges from InfraWorks into Civil 3D

Just because I’m not discussing them here doesn’t mean they aren’t great improvements, it’s just that I haven’t installed Vault 2016 yet and I haven’t had a chance to learn what an IFC file is yet.

Oh, one more thing before I get started, NO DRAWING FORMAT CHANGE! That’s right, 2016 has the same drawing format as 2013. They’ve broken the 3 year cycle on changing the drawing format.

Manage Data Shortcuts

This one is sweet! Ever have a drawing move or have IT move data to a different drive? I know what you’re thinking, “Brian! They would never do that!” Yeah right. Anyways, this command allows you to repath your data references to a new drawing or to the original drawing if it moved on you. Not only that, you can replace an object in your drawing with a data reference and all the references to that original drawing are maintained!

Manage Data References

Another fantastic thing that isn’t advertised in the “What’s New”, YOU DON’T HAVE TO SAVE PRIOR TO CREATING DATA SHORTCUTS!!!!!!

Alignment Targets By Layer

If you have several alignments that a corridor region needs to target, you can now choose the targets by layer.

Section View Display Direction

Section Views have finally caught up to Profile Views, they can be drawing “Right to Left” or “Left to Right”. This should make all those hydraulic modelers happy!

Subassembly Composer Loop

Have you needed to put benches in your daylight or a series of walls or something else repetitive in your subassembly? New in 2016, you can now add a loop component that will continue until either a criteria is met or a maximum number of iterations has been done (this keeps it from blowing up on you).

Subassembly Loop

Exclusionary Catchments.

I’ve always liked the idea of creating catchments (or drainage areas or drainage basins or whatever term they use in your area) in Civil 3D from a surface but the problem has always been, but what if I need to subdivide this large basin into smaller ones? For example, I have a road with inlets at a low point and so I create a catchment to that inlet but, the flow in the street is too big. What do you do? You add an inlet upstream and then define a catchment to it. Now in 2016, this new catchment area will be removed from the original catchment so you won’t have duplicate areas!

Crossing Pipe Labels

We’ve been asking for this one for a LONG time and it’s finally here! We can label the a pipe where it crosses in a profile view!

In the image you can also see the different crossing properties that you can place in your label.

Pressure Pipe Labels in Section Views

In addition to being able to label pressure pipes crossing in a profile view, you can also label them crossing in a section view as well.

Import Bridges from InfraWorks

So, you have InfraWorks 360 with the Roads and Highways and the Bridge tools and you’ve created a nice bridge in InfraWorks. When you import that model into Civil 3D 2016, the bridge comes along as well now!

Bridge from InfraWorks into Civil 3D

Bridge from InfraWorks into Civil 3D

So, what do you think of Civil 3D 2016?

A lot of people I’ve talked to recently have been confused on the new release of InfraWorks 2015. Do I have that tool? If not, why? And where do I get it?

First off, if you haven’t checked out the new InfraWorks, you really should. They’ve made some great changes to it! It’ has a brand new user interface (UI) and some great new functionality.

InfraWorks 2015 User Interface

InfraWorks 2015 User Interface

That’s all nice but, what is available? Well, there are now two versions of InfraWorks for 2015: InfraWorks and InfraWorks 360. If you have one of the suites (Infrastructure Design Suite Premium or Ultimate or the Building Design Suite Ultimate) you have InfraWorks.


What’s available in InfraWorks? Well, pretty much everything you had in the Premium Suite from last year. This includes:

  • Creating the existing model from GIS data
  • Laying out proposed features (roads, buildings, plants, coverage areas, etc.)
  • Visualization and storytelling
  • Sight analysis
  • Theme features based on their data
  • Shadows and lighting
  • Many more

InfraWorks 360

So, what do you get if you have InfraWorks 360? Well, first off, you get everything you get with InfraWorks plus:

  • Online collaboration with other InfraWorks 360 users.
  • Publishing scenarios for online viewing by anyone.
  • Using Autodesk servers to convert 3D models to InfraWorks data.
  • Model Builder – Create a model simply by choosing the area you are interested in on a map (this is a preview function and may not be in the product in the future).
  • Add-on advanced design tools

Basically, if it touches the cloud, you need InfraWorks 360.

Missing Features?

At first glance, it may seem as though there are some missing features such as the Roadway design, profile optimization, intersections, etc. Well, these are available in that “Add-on advanced design tools” listed above but, they are just that, an add-on. They don’t come with either InfraWorks or InfraWorks 360 but if you want that functionality, they only work on InfraWorks 360, not InfraWorks.

Autodesk Roadway Design

The Autodesk Roadway Design add-on allows you to do the things that were available in the ultimate suite from 2014.  This includes:

  • Design Roadways with true curves and spirals
  • Apply different styles and number of lanes for regions of a road
  • Profiles with vertical curves
  • Intersections between design roads
    • Ability to edit curb returns and add in turn lanes
    • Create site triangles
  • Profile optimization (requires cloud credits)
  • Corridor optimization (requires cloud credits and is currently a preview functionality only)
Design Road Intersection with Site Triangles

Design Road Intersection with Site Triangles

Autodesk Bridge Design

The Autodesk Bridge Design allows you to create very realistic bridges as well as edit things such as number of piers, pier locations, concrete or steel, etc.

Bridge created in InfraWorks 360

Bridge created in InfraWorks 360

Other Add-ons

When InfraWorks 360 first came out for the 2015 version, there was some preview functionality (it timed out May 7th, 2014). Examples of this was Drainage Areas and Culvert Design. The Culvert Design tools did just that, it added a culvert under the roadway. The Drainage Areas would delineate the contributory area to a design point or road that crosses a drainage way. Remember, these are previews of upcoming technology and there is no guarantee that they will be a part of the final product (in other words, don’t buy the software expecting this functionality).
Culvert Design


This is the important part! If you have a suite version of InfraWorks, you’re good to go. Nothing new here. But, if you want InfraWorks 360, there are some things you have to be aware of.

Desktop Subscription

InfraWorks 360 and it’s add-ons are only available via Desktop Subscription. What is Desktop Subscription? It’s, in essence, a term license of the software. You purchase a license of InfraWorks 360 and you get access to it for a set term (1 month, quarter, or year). Another thing to note, this license is assigned to a specific user. That user needs an Autodesk ID (they are free) and that license will be assigned to that user. Your software manager can assign those licenses to what ever user in your organization you want.

The nice thing about Desktop Subscription is you can get the software for just the time you need. Got a project that you need 10 users to be able to access the software but the project is only going to last a year, you only pay for that software for a year.

More Information

If you want more information, check out the Autodesk website for comparing the different version of InfraWorks. Since the Autodesk website often changes, I’ve printed out that page and included a link to the .pdf HERE.

If you have any questions about this, make sure you talk to your reseller. If they can’t help you, let me know and one of the sales folks at CAD-1 can help you!

As I’m sure most of my readers are aware, with the 2013 release, the ability to import images from Google Earth was not included. The fine folks at Autodesk have been working on getting us a replacement and this is it (at least for imaging). When you are in a drawing that is georeferenced (the tutorial file “Intro-1.dwg” works if you want to test it out) all you have to do is turn on the image.

In the drawing (with the assigned coordinate system), simply go to the Geolocation tab on the ribbon and choose the Online Map type you want.

Map Type

Map Type

You’ll need to log in to your Autodesk account (if you don’t have one, they’re free) and agree to the terms, etc. etc. Once you’ve done this, your image just shows up (provided you have a decent internet connection). Nothing too new here, we’ve been able to do this for a while (see my other posts HERE and HERE).

So, what’s new in 2015, THEY PLOT!!!!!

Ok, so there’s another step you have to take before they’ll plot but it’s not difficult, you have to capture an area. Once the imagery has been displayed in your drawing, go back to the Geolocation tab and choose “Capture Area”.

Capture Area

Capture Area

After you have captured the area, a new object type will be created, a GEOMAPIMAGE or “Map Image” as it’s displayed on the ribbon when selected. This object will plot as you can see in this plot preview:

Plot Preview

Plot Preview

Another really cool thing about the GEOMAPIMAGE is, if you edit the image extents, the image will update. Simply select the image frame, adjust a grip, and the image updates. Additionally, if you need a better resolution or less resolution, when you select the image, you’ll have those options on the Ribbon.

Oh, and by the way, this isn’t really a Civil 3D feature, this is a core AutoCAD feature!

So, if you haven’t heard yet, Civil 3D 2015 is due out soon. Wondering what’s new in the latest and greatest? Well, the C3D team has released the help for 2015 already. If you are interested, you can find the new features listed HERE.

Stay tuned. As the software gets released, you’ll see some more detailed information on exactly what’s in the new version.


So, Civil 3D 2013 is just around the corner and I wanted to let you all know a few of my favorite things in this release.


Well, I can’t really comment on the performance yet as I haven’t had much chance to push the software around but, if you listen to those in the know, they’ve made some serious improvements to the performance.


There are some major improvements to the survey tools in this release. In fact, there is an entire new tab on the ribbon for your survey tools. What’s the big thing? Querying your survey database. One of the things I’ve always found awkward about the survey database is the disconnect between it and the drawing. With this release you can query your survey database and add the results of the query directly to a surface. If you add additional data to the survey database that matches the query, when you rebuild your surface, it will update (in my testing, the surfaces wasn’t marked as out of data if the survey database changed).

Survey Query

Survey Query Ribbon Tab

Now that’s pretty cool and really useful for surveyors but, there is also the ability to create a line label, WITHOUT A LINE! How many times have I been asked if you can do this? I’ve lost count and now I’ll be able to say, YES!

Line Between Two Points Label

Basically this tool creates a phantom line that is labeled. Grab the label and you can adjust the points it’s labeling between.


I’m an engineer. Why did I get into engineering? I wanted to drive trains. Three years into college and I realize that I won’t be driving any trains (I was wondering what statics had to do with trains) but now with Civil 3D 2013, I can design rail lines. There are new alignment types and settings (I’ve seen many times on the discussion groups people asking about Degree of Curvature and now we have it). Honestly, I’ve not done much with the rail tools in 2013 so I’ll leave that for someone else to write up (at least for now).

Rail Cant

The corridor creation has a new dialog box that makes it a bit easier. It’s a small improvement but hey, I’ll take anything they’ll give me. The assemblies have had some very nice improvements. When you add a subassembly to another subassembly, it will detect the correct side that it’s on for you so you don’t have to constantly change the sides as you are creating the assembly. Additionally, you can replace an existing subassembly in an assembly as well as insert a subassembly between two subassemblies.

Insert Subassemblies


The Volume Dashboard Extension is now a part of the program. If you have checked out this great tool, check out the write up I did on it earlier HERE.

One thing that I always struggled with is when you need to cut out one surface at the limit of another surface. Not a difficult task but if you change these surfaces, the process for adding the boundary again is very manual in nature. Now you can simply add one surface as a hide boundary to another surface (be careful not to get into a circular reference issue).

Surface as Hide Boundary

Pressure Networks

Yup, you heard me. You can now model pressure networks in Civil 3D 2013. There is a brand new type of object, a Pressure Network. It has it’s own parts lists and everything. Bends, tees, crosses, valves, etc are all available for you to add to your network. This is a pretty big addition to Civil 3D and I haven’t had a lot of time to get down and dirty with this yet so stay tuned for more posts on this topic as I learn the ins and outs of this.

Hopefully you’ve seen something here that makes you go, “Oooh! I can use that!”
