create ribbed profiles

Hello,

As a CAD beginner, I can get along very well with LibreCad for simple things. It like it very much.
Since I only use it for model airplane building, I'm looking for a way to create ribbed profiles.
Is there perhaps a “plug-in” for this where rib profiles are already stored and can only be adjusted to the required size.
The CAD software “CADasCAM” has something like that that I really like.

Thanks
