LSP Lines with intersections width / length of the area

[wiebe]

I'm working on a new LSP but I can't seem to get this to work

Get the next error message

( bad argument type: lselsetp nil  ; error: bad argument type: VLA-OBJECT <Entity name: 20eac6f0410>

What's wrong with it!

Would like to expand it with a table on the drawing overview per width with the total m1

calculate-area.lsp Sampel.dwg
