Select Primitives(Faces) by Angle


saca

Recommended Posts

hi,

I want to select Primitives(Faces) by the angle of  selected primitives.

You can see this useful  function on 3dsMax Polygon modeling.

if you select some Primitives(polygons), other neighbor Primitives are selected by the selected Primitive angle.

thanks.

Group SOP is Very useful.

but i want to select primitives by angle from selected Primitive(s).

example; picture below, i want to Select Primitive 24-30 by angle from Primitive 30.(not pattern 24- 30, the reason my scene is build by very complex geometry.)

(If you can, the primitive 30 is selected by mouse operation.)

 

3dsMax select by angle "Planar threshold".

Hi, check Group SOP, you can specify normal direction there and it will add polygons with similar normal to the group.

The problem i found with the group soup is it doesn't seem to take care of your custom normal. I modify my normal using box Hexplanar mapping masks and i wanted to extract group using these normals. Thr group sop will not allow you to do this.

You have to write yours
