When trying to save a drawing in ZWCAD, you may see an error message like:
"File save failed! Trial version does not support saving files exceeding 1000 objects! Please make sure that you have been authorized and registered correctly. For more information, contact ZWSOFT CO., LTD."

The software is not activated, or the trial period has expired. Without a valid license, drawings with many objects cannot be saved, and printed files may show a watermark.
To remove this limitation, contact us or your local reseller to purchase a license, and activate ZWCAD with a valid license code to save drawings without restrictions.
Note:
When you first install ZWCAD, you receive a 30-day free trial with full access to most features. Functionally, the trial version is the same as the official version.
After the trial period expires, if you do not activate ZWCAD with a valid license, certain functions such as saving, printing, and exporting will be restricted.
Trial restrictions include:
● Cannot save drawings with more than 1,000 objects
● Watermark added when plotting or publishing
● Cannot save drawings as DXF
● Export and Copyclip functions are disabled
● Cannot export WBLOCKs containing more than 1,000 objects
To unlock full functionality, please activate your ZWCAD with a valid license.
