Is that normal?
A plane + a circle (on the plane) give with boolean "merge" a minimum height to the circle?
( here I have erased the "center disc" result on the "front piece")
Ps Same result when the circle is over the plane

Hi Pilou, this one is definitely a bug, thanks for reporting it!

The bug is in how non-volumetric surfaces are handled in combination with auto-extruded curves. I've fixed this for the next beta so it will work in the expected way.

hello all :)

thank you Pilou :) for the merge functions info.


ciao

Cool research !
yes crazzy forms can be made with a minimum effort with the "merge" function :)

Is that normal? (it's a same curve // but more long for the second)
I suppose yes but...

Hi Pilou, it is normal for this type of situation to fail.

It would be nice if it could work, but handling self-intersecting objects becomes much more difficult. Generally if a curve or surface folds and intersects itself it will not work properly for operations that involve calculating the intersections between objects.

Thx : It that I had supposed but want to be sure :)
