Most of Mesh+ components not working in RH 7.3

Most of the Mesh+ components are not working on my machine running RH 7.3.

It may be inaccessible due to its protection level.

Does someone have an idea how to fix this?

Thanks a lot,
Rudi

Hm, most components didn’t even work in versions of Rhino for macOS before 7.3.
If I remember correctly, many components in Mesh+ are open source, so theoretically they could be rewritten in Python or C#.

Are you looking for something specific?

interesting… do not remember them not working before - but probably I havent used Mesh+ so much in Rhino Mac.
The components I need would be for example Mesh Extend and Connected Edge Length

Does Connected Edge Length simply give you the total length of all edges connected to a vertex?
And what exactly does Mesh Extend do, meaning what is extended where and how?
