Issue: 

When opening the DWG drawing, there will be a prompt (warning) "This drawing is generated by an Educational Product, not for commercial use. Do you want to continue". And when printing, the word "Designed by ZWCAD academic version" will appear around the drawing. How to make it not displayed?

Solution:

  1. The ZWCAD system variable EDUCHECK controls whether to display educational version prompts and plot watermarks.
  2. Enter the command EDUCHECK, press Enter, and set the value from 1 to 0.

Note: this solution works for ZWCAD 2021 and later versions.
