Creating section curves from frames and brep

Hi all,

I want to create 12 section curves on a brep using the brep plane sec and perp frames. On the perp frames tool I used the number of segments: 12 but in total the tool is creating 24 curves (green marked). Maybe someone knows how to solve the problem? The same think is working for the horizontal section but I am using there a xy plane as basis. Is there any difference between using Perp Frames and Planes? Thanks in advance!

Because each plane always intersect your brep twice.

You should remove half of intersecting curves.

Above One is only works with even number divisions.

This one is better.
