I was wondering if someone could help me with an old LSP that I did not write and I know nothing of LISP code. I have an LSP that draws a tank head and has recently started erroring out for no apparent reason. I enter two values, the tank diameter and the thickness of the head, then get the error
Command: asme1
What is the outside diameter? 144
What is it's thickness? .25
; error: bad argument type: FILE nil
After you enter the thickness, it is supposed to ask you for an insertion point but of course it never makes it that far. Can anyone give me some advice please? It would be much appreciated. Thank You.
I have attached the LSP, any suggestions??
