DWGEditor needs a Trusted Digital Certificate in order to run macros at the High Security level. Why DWGEditor needs security levels and Solidworks does not is beyond me. That being said, I can create a certificate by following these steps. However, when I try to sign my macro project, it does not keep the signature; that is, the Certificate Name in Tools-Digital Signature shows No Certificate even after I assign one and save it. Has anyone else encountered this problem and know how to resolve this issue?
