Applies to: ZWCAD 2015
There may be several reasons as follows:
1. Parameters called by the CAMMAND function are wrong.
2. Using the function that ZWCAD+ does not support at present.
3. Using the system variables that are not existed in ZWCAD+ like VTENABLE.
4. Problem of SSGET parameter.
5. Script error.
6. Forget to load .pgp file. You can change customize .pgp file to be a name of ZWCAD+.pgp so that ZWCAD+ can load it automatically when you open it.
7. Calling VBA macro with Lisp. The VBA macro write in AutoCAD cannot be applied directly in ZWCAD+.
8. Using .arx files. ZWCAD+ does not support this format at present.
