Deletes primitives, points, edges or breakpoints.
Blast is designed to remove geometry that you select interactively in the viewport, as opposed to Delete which is a more procedural tool.
Subset of the input geometry to delete.
The type of entities to delete.
The removal of geometry can change the effective normals on the surface. This option will recompute any point normals to ensure they reflect the result of the deletion.
|Delete Non Selected|
Negates the sense of the selection. Instead of deleting anything selected, will delete anything not selected. This is very useful to isolate some geometry.
Note that Breakpoints groups cannot be inverted with this toggle.
|Fill Simple Holes|
Caps complete holes that result from the deletion of points. A hole is said to be complete if it is a negative polygon i.e it has borders. This option works only with non-manifold geometry. After capping, it removes degenearate polygons that are formed during the deletion.
Fill simple holes is only enabled when point groups are used for deletion.
|Delete Unused Groups|
Remove any groups that are left empty after deleting points/primitives.
