Apparently, this won’t come as a surprise to those that know AutoCAD Architecture but, we can add any property we want to any object in our drawing!
Turns out, it’s a lot easier then you would think.
First thing to do is run the command PROPERTYDATA and go into the “Sets” command line option. This will open up the “Style Manager” dialog box (no, not Civil 3D styles…).
Once in here, simply right click on Property Set Definition, choose New, and name the new style (I named mine “Featureline Curbs”). On the “Applies To” tab on the right, simply select the type of object you want to create a custom property for (I chose a featureline for this example).
Finally, go to the Definition tab and add your new properties. Click the top button on the right side to create the new property, and then simply fill in the data. I created a new property for a featureline that represents a curb so I know what type of curb it is (defaults to “vertical”).
Settings for the new property
When you select a featureline now and go into the AutoCAD Properties, you’ll be able to see these new properties and edit them independently for each object. There is a trick, however, to be able to see them. On the Extended Data tab of your properties, you’ll need to select the object (or objects) you want these properties to be assigned to and then click on the button at the bottom of the properties, “Add Property Sets”.
This will then bring up a dialog box that will allow you to choose the property sets for this (these) object(s). In this example, I only have one but you aren’t limited to just one.
Now, when you select that line again, and go to the extended properties in your AutoCAD properties, you’ll see those properties.
Now, comes the fun part, figuring out what we can do with this! If you have any ideas, leave a comment below. Keep in mind, I just found out about these and I haven’t really had much time at all to play around with them yet but they’re there so go start using them!
