Hello,

How do you remove easily the faces that are coplanar to the reconstruction region ?
It’s very difficult when the surface intersect the 3D region (Neither the edge length method nor side selection works).
I tried to do in blender but it’s very slow by hand (coplanar selection or similar normal selection do not work well there)

It could be convenient to have such filter.

Thanks

Ben

Hi Benny,
to do so go to Scene 3D tab/Tools/Mesh Model/Advanced

Hello,

Thank you Otrhan for your fast answer (as always).
Marginal triangle does not work well :

There is still so many tiny faces to remove by hand…

Thanks

After marginal triangles are deleted and you want to delete the remains you need to play with the edge threshold multiplier to achieve your goals.
Also, you can slightly move (shrink) the reconstruction region and use Cut by box option.

Thank you for your answer by none of the 2 methods seems to work because :
My model has also large edge inside that I want to remove so edge Threshold does not work (and also some triangle on the side are very tiny)
When I shrink the region and cut by box, I got new polygons on the new region, so the problem remains…

But I would be good to have such option (to enhance the “marginal triangles” selection)

In Cut by box settings have you set Fill cut holes to No?
