The program marks all drawings modified with a student version as a student drawings with watermark symbols added to prints. The watermark symbol is shown regardless of license type.
The program adds watermark information whenever you save a drawing with a student version. In practice, the program adds a watermark even if the drawing was started using a non-student version. You are not allowed to process commercial drawings with a student version. Once the program saves a watermark into the drawing, it cannot be removed.
If you use a student version for something else than educational purposes, we require a statement from the customer, on which basis the watermark can be removed for a specified time. This kind of commercial use is charged based on terms of contract.
