Quick post about a small annoying and important aspect in Blender modelling.

I thought boolean modifiers don’t really work because some tests I had made gave wacky results. Actually I forgot to Apply Scale and Apply Rotation in object mode on the geometry before using the modifier. I’m not sure Apply Location is needed.

Other stuff I check before using modifiers are removing doubles and recalculating normals in edit mode (all faces selected).

With all these properly set, I can punch a hole! Not a very tidy one but here it is:

So now I’m ready to try booleans some more – seems they are not so bad after all. Just have to test them on more complex objects and keep an eye on those triangle faces that don’t look so good in a mesh.

The above applies to other modifiers too – like solidify and bevel.

Happy blending!
