It’s just been announced that the Subassembly Composer that has been available at Autodesk Labs is now an official add on to Autodesk Civil 3D 2011 and 2012. If your Civil 3D is on subscription, log into the subscription website and go get it (well, on or after July 7, 2011 that is). I was given a bit of a sneak preview of this by Dana Probert, Peter Funk, and Dave Simeone and I  got to admit, it looks really cool! I’ve always told my clients that 98% or more of any type of assembly they needed to create could be done with the out of the box subassemblies and the rest could be done if they knew how to program in .net. Well, this tool just opened up all that custom subassembly creation to the masses of people that don’t know .net (including myself).

You can add the basic building blocks of any subassembly; points, links, and shapes using this tool. However, the real power of this tool comes from the additional options, primarily the Decision and Switch tools. These are basically your IF THEN statements within the subassembly. If I’m in fill, do this, if that link is shorter than that other link, do that.

And then you have the Auxiliary tools. Place a test point here and get the intersection of a link from a specific slope from that auxiliary point. Is the elevation of that auxiliary point lower than the end of that link?

The possibilities of this tool are mindboggling to say the least. Want more information? Check out Dana’s video HERE or Cyndi’s blog post HERE, or even those folks over there at HERE (Matt Kolberg to be specific).

This is some pretty exciting stuff so look for more information around the web or possibly even here.
