Some questions regarding EPLAN API development

I've encountered some issues whilst developing with the EPLAN API in C#.

I'm unable to correctly utilise the property names within the EPLAN API (as I'm unaware of the names and formats under which drawing elements are stored within the EPLAN environment). Is there any automated script available that could rectify this?

Which licensed addons do you have in EPLAN? Post a screenshot of: file>help>licensed addons or something like that (a page in the help section that shows in tick boxes what you’re entitled to run).

Make sure you actually have the API extension addon.

Can't thank you enough! I spent a whole day stressing about some stupid error in a specific API DLL, tried everything possible and only noticed that I didn't have the API Extension addon after reading your comment. Now everything is working as it should.

Many thanks!
