Understanding Digital Signatures in AutoCAD

A digital signature in AutoCAD serves as an electronic security measure that verifies the signer’s identity. Unlike a traditional handwritten signature, it uses encryption to provide authenticity, ensuring that your drawing has not been altered after signing.

2. How long is a digital signature valid?
Digital signatures typically remain valid for one to two years, depending on the issuing Certifying Authority and their regulations.

3. Can I use a digital signature for multiple drawings?
Yes, you can apply a digital signature to multiple drawings, either individually or through a batch processing tool available in the AutoCAD software suite.
