Walls Generated from a AutoCAD file

I am having trouble getting my script to work I was wondering if someone could help me figure out what is going wrong. I wanted a script to auto-place walls over the top of a CAD Link file. I am very new to the software so I am also trying to learn it simultaneously.

Hi @artvazquez451 ,

The screenshot you uploaded has unreadable node names since you took the screenshot whilst zoomed out too much. Please zoom in as far as you can and use the camera tool in the top right corner to take a high res screenshot.

Also, sharing the dynamo file, together with a host file helps us (and yourself) a lot to pinpoint the problem. Some screenshots of the geometry are useful aswell.
