Hi
@Stefan KauffeldThe plugins for Tekla Structures and for Connect are installed to different folders. Also, Structures plugins and Connect plugins are handled differently. Connect uses plugin installers, while structures plugins are part of the Structures deployment. You would not be able to replace structures plugins with connect plugins...
So "Does a new version of a plugin from Trimble Connect work for Tekla, for example," - No
" is Tekla dependent on an 'older' version of the plugin?" - Tekla Structures has it's own deployment mechanism for it's import plugins unrelated to the Connect import plugins. Connect plugins installations do not affect Tekla Structures import capabilities in any way.
Tekla Directory: C:\Program Files\Tekla Structures\2020.0\nt\bin\referenceplugins
In general the application installers will remove old version of the plugins - so there shouldn't be a need for you to remove any manually.
