The extension is an offset extension it offsets multiple lines. I cannot remember the name. I was going to use the extrud tool to create walls with it
Tig’s Smart Offset perhaps.
I don’t know if I am explaining myself very good I had found an extension that would create simple walls or multiple layer walls and you could change the thickness of each wall. I hope I am explaining myself better.
I can’t remember the name or where I found it.
That was it thanks
