Are you able to tell me which version number you are on please? There was a hotfix that did resolve this originally.
If you type KAB in the command bar, it should list the version number.
If you were to type 3DREPS in the command bar, it will give you the option to globally toggle between 2D and 3D Representations.
Hope this helps.
I have just responded to your email with a resolution.
If it is still an issue, please let me know.
KeySIGN 19.5 is compatible with AutoCAD 2015-2019, however the latest version is KeySIGN 19.6 and is compatible with AutoCAD 2020.
This has been picked up as a support issue and will respond to you separately.
It looks to be that your KeySIGN Profile has corrupted. In order to create a new Profile, please follow the link below.
