Hi Michael, the problem is this:
When I select a line, a menu should open that allows me to select the various HeA profiles, etc. Then, based on the one I choose, a solid with the chosen profile will be created from the line. Unfortunately, it doesn't work. I'm not a computer engineer, but a construction engineer. I don't have any programming language skills.

Hi JOCONDOR, I'm sorry but some programming language skills are a necessary prerequisite to be able to make MOI scripts.

AI tools do not seem to do a very good job making MOI scripts. I'm not exactly sure why that is, possibly there is not enough data for them to train on.

You may need to find a partner who does have some programming background to work on your project.

Or perhaps try the node editor, it is a type of simplified graphical programming language:

Thanks for the advice. I'll try to download the plugin.
