Intersect (Boolean)¶

Performs Boolean operations between the selected and unselected geometry.

Selecting a sphere and performing an Intersection, Union, and Difference with a cube.¶
Dica
Hide geometry by pressing H to exclude it from the operation, then Alt-H afterwards to unhide it again.

The Operação booliana can perform these same operations non-destructively between different mesh objects.
The Adjust Last Operation panel offers the following options:
- Boolean Operation
- Intersecção:
Only keep the volume that’s inside both the selected and the unselected geometry.
- União:
Remove the interior faces between the selected and the unselected geometry.
- Diferença:
Cut the selected geometry out of the unselected geometry, then remove the selected geometry.
- Solucionador
Algorithm used to perform the Boolean operation.
- Rápida:
Uses a mathematically simple solver which offers the best performance; however, this solver lacks support for overlapping geometry.
- Merge Threshold
Tolerance for close faces to be considered touching. It may be useful to increase this when some intersections aren’t detected that should be and when extra geometry is being created because edges aren’t detected as overlapping.
Aviso
A threshold approaching the size of faces may cause very slow calculation. In general, keep this value small.
- Exact:
Uses a mathematically complex solver which offers the best results and has full support for overlapping geometry; however, this solver is much slower than the Fast solver.
- Swap
When using Difference, cut the unselected geometry out of the selected geometry instead of the other way around.
- Self Intersection
Correctly handle self-intersection in the participating geometry, at the cost of performance.
