Thank you for your detailed explanation. Unfortunately I can not read French.

English would be OK.

I do not understand how to align the frame properly on X / Y and the dimensions still fit.

I mean with frames a hull slices seen from the front.
If the frames are not properly centered, a banana is created.

Hello Alain.

I understand your solution.

I'm just worried that at 14 cuts a banana is produced.

All my frames have the zero point in the middle.
It would be nice if the program offers an option that cover the zero points.

Another point.

Dimensions.
is there a 1: 1 function for DXF parts?
I have ...

With Jedicut you can cut DXF contours.

How to achieve that two different profiles are automatically
concentric?
default, they are always left justified.
