Hello I am using version 3.24.3.0 on a Mac. I use QCAD to draw model aircraft plans. I am trying to find a way to take a wing rib and duplicate it and scale it at the same time to create all the ribs for a tapered wing. I hope you understand what I'm trying to do. I have attached a top view of wing ti illustrate. I have not drawn the rib profiles yet.

Re: Duplicate and scale
Perhaps through morphing? Just a thought as I've solved similar problems with the morph tool:

Thanks, that looks promising.
Re: Duplicate and scale
Hi,
The problem will be that an offset of an airfoil shape is not a new correct airfoil shape.
Although it looks that way for us.
I don't know if morphing will level out the differences good enough.
A little off has a huge impact.
There are calculators for that.
