Hello all, I’m trying to get Dynamo to return the area of a hatch or polyline In AutoCAD/Civil3D so that I can use that information in a list for further processing. Additionally, is there a way to accomplish standard ACAD commands like “explode” and such? Thank you

Hello! Civil3D 2020 is what I use with Dynamo (until the inevitable upgrade ha).

@Yellowjacket98 here are 3 options for you using the Civil 3D Toolkit or OOTB nodes. [Areas] And here is a Python script if you want to wrap it all up into a single node. [areaPython] import clr # Add Assemblies for AutoCAD clr.AddReference('AcMgd') clr.AddReference('AcDbMgd') # Import refer…

[image] Yellowjacket98: Additionally, is there a way to accomplish standard ACAD commands like “explode” and such? For exploding objects, there is already a node for that. [Explode] But for sending other commands to the command line, here’s a quick Python script. The input should be a stri…

Man thanks for that! I ended up getting something very similar to your first posting to work yesterday morning. The good thing is you confirmed my route was pretty close. But as far as “explode”, I didn’t even type that into the search bar for some reason. Those are both super helpful. I had tried…

What impressed me with the Dynamo route was that it properly subtracted regions—my LISP routine would never process a solid hatch and its boundary properly when I was trying to show overlaps and differences. The closest I ever got was using a dot pattern and then ensuring it was to a proper scale so…

Sounds similar to this. [image] Intersect-area Civil3D Hi guys, i am trying to create a script to provide a total impervious and pervious area in a site. We use hatches in cad to calculate the total so i am importing them into dynamo. but for does areas that intersect i n…

That is pretty much what my aim was! Sometimes I need previous vs impervious, and other times I need it broken out over more than two coefficients. Early on I had even tried using 3D (flat) surfaces to compare, set at different elevations based on coefficients, but it would combine some of the surfa…

What worked for me was selecting the polyline, creating the hatches, and then converting those to regions for the calculations. Then it’s a matter of clearing the items on the hatch list (by layer) if you don’t want them anymore… especially if you need to rerun the calculation later once an area has…

The send to command line python script is interesting. Is there a way to send options along with it as well? I tried sending a list of commands but that doesn’t work. What I am trying to do is: Use your python script, send the : HATCHGENERATEBOUNDARY and send All with it. Something like: for i in…
