Mesh Intersection, often called "boolean functions", is a different
way to model. The Blender way is to model around holes, with Mesh
Intersection you first do your models and then cut holes in
Mesh Intersect is avaible in the Editbuttons, F9. Select the faces
(this means, select the vertices in EditMode which form the
that need an intersection and press this button. Blender now
intersects all selected faces with each other.
Best example to test this, is with an IcoSphere and a Cube. After
intersection, you can select with LKEY
the individual parts. By
removing certain parts, a user can easily obtain a boolean operation
like OR, AND or XOR.
To ensure a proper intersection, it is important to follow these
- Make sure no co-planar faces intersect.
- Always make sure faces have as few
intersections as possible, for example
intersecting a a single pane with a tube works
better when the plane is subdivided a few
- The 'secret' trick: rotate each part slightly, just a
fraction of a degree.
- Before intersecting, save the file or press
to create an UNDO possibility. It still is
possible to make Blender crash with this
