getpat.lsp error

[kamilee2011]

Hello everyone?

I got a recommendation for a Lisp named getpat.lsp to export AutoCAD's hatch as a .pat. () <- Lisp Code

Many people seem to be using this Lisp well, but I have an error.

"
Command: GETPAT
Select hatch: ; error: bad argument value: positive 0
"

I tested both versions of AutoCAD 2011-2017, but the results were the same. Also, no matter how I search, there is no advice to solve this problem.

I have already spent too much time solving this problem. If you know the solution to this problem, please let me know.

Two suggestions.

1. Contact the author of that lisp file. Nobody knows it better than him.

2. Post the DWG with the hatch pattern here, someone may be able to help. But w/o the drawing, we are just guessing.

I've used it for many years, never had a problem. It outputs a pattern file, but I modified it to place it in a folder of my choosing by replacing line 58

(setq outf (strcat hnam ".pat"))

with

(setq outf (vl-string-subst (strcat hnam ".pat") "getpat.lsp" (findfile "getpat.lsp")))

to place the pattern file in the same folder as "getpat.lsp". You could also call out a folder like:

(setq outf (strcat "G:\\BeaufordT\\Autocad\\Application Data\\Customization" hnam ".pat"))

Like rkmcswain said if that doesn't help post the drawing. At worst we can post the pattern file for you.

Tested in version 2017 of Civil 3D.
