To select the block insert (block reference) to display the signature information, invoke the JTBWDSSETSIG command and select that block insert. You're now ready to use your digital signature stamp. To digitally sign a drawing, you will need a digital signature. If you don't have one, you can procure one from (for example) docusign.com. Invoke the SECURITYOPTIONS command in Autodesk® AutoCAD® 2015 and older or the DIGITALSIGN command in AutoCAD 2016 and newer to add your digital signature when it is saved. Now when you plot your drawing, the digital signature plot stamp will display the current signature state of the drawing. Addin usage is demonstrated in the short screencast included in the "Demo" folder. The sample DWG used in the demo is also contained in that location. Locate the Demo folder by using this path "%ProgramFiles%\Autodesk\ApplicationPlugins\JTBWorld-DigSigStamp-Trial.bundle\Contents\Demo". You can copy and paste the path to the address bar in Windows Explorer (File Explorer in Windows 8 and newer) and press enter.

1. Displaying the plot dialog flags the drawing as modified. This is normal AutoCAD behavior (try displaying the plot dialog, closing it, and then closing the drawing and you'll see AutoCAD ask you to save changes). This app accounts for this during plotting but does not remove the 'modified' flag.

2. For performance reasons, the digital signature stamp is not automatically updated every time the drawing changes. Therefore, the stamp shown while editing a drawing may be incorrect. Regen the drawing to update the stamp. (The stamp will display the correct graphics during plotting).

3. DigSigStamp has not been designed to work with the following:

• Signature blocks inside nested blocks
• Signature blocks in external references
