For those of you that have SPOOLCAD’s add-on to your existing AUTOCAD, and also have Mech-Q installed on your computer, it may cause difficulties when installing or operating your SPOOLCAD software.

If you have installed Mech-Q software, or even if you uninstalled Mech-Q, there is an AUTOCAD lisp routine that conflicts with SPOOLCAD’s operation. Since Mech-Q adds an initialization statement in that lisp routine, you need to make adjustments to that file.

It is a simple fix to have SPOOLCAD up and running!

Here’s how to do it:

You must edit the ACAD202xDOC.lsp – lisp routine document file and adjust it in one of 2 ways:
Note: [x] represents your version of AUTOCAD; 2020, 2021, 2022, 2023, etc.

  1. Delete the Mech-Q reference line (if the software is no longer installed on that computer)
  2. Remark out the line with the Mech-Q reference, use the “;” semi-colon character

The file to edit is located in the following folder:

     C:\Program Files\Autodesk\AutoCAD 2022\Support\en-us\

Note: AUTOCAD 2022 is used in the sample above, please adjust for your version of AUTOCAD.

To be safe, make a backup copy of acad2022doc.lsp then open the original file.

Search for the Mech-Q reference line in the code, it should be near the bottom of the file.

Use option 1 or 2 above as appropriate.

Save and exit the file.

Restart the SPOOLCAD software and the problem will be resolved.

It’s that easy!
