Thank you so much for your post and sharing your script. I downloaded it and there are a couple of errors. I am quite new to Dynamo so not sure how to fix it. Hope you don’t mind me asking for some help with this.
Your script is exactly what I need for my work. I am an AV consultant designing sound reinforcement systems for large venues like performing arts theaters, stadiums, arenas, etc. I use an acoustics and sound design application called EASE where I have to model rooms in their native format which is terribly time consuming, so been looking for a way to export only the internal faces of a room including ceilings and floors to DXF that I can import to EASE. I can export a room to DXF, but it exports all the elements of a wall, ceiling, etc.as 3D elements with thickness and EASE requires only the surfaces facing inside the room, so I end up spending hours editing the EASE model to remove all the stuff it doesn’t want to see.
Looks like it’s been a couple years since you posted it. Do you have this module updated or can you help me with these errors?
