Inverse Selection swaps the selection: the selected triangles or points become unselected, and all the others become selected. Use it when the part you want to keep is easier to select than everything you want to remove.
Invert the selection
- Select some triangles of a mesh or points of a point cloud, for example with Select Primitives.
- Click Select › Inverse Selection.
The command works at once, without a panel, on all meshes and point clouds selected in the Scene Tree. A selected object with no selection becomes fully selected. The button is also on the Points tab; it has no keyboard shortcut. To go back, click Inverse Selection again or use Undo (Ctrl+Z, or Cmd+Z on macOS).
Keep one part and delete the rest
A typical case is a scan that captured the table or the stand around the part. The pictures show the same steps on the fandisk CAD test model, where the top face is the part to keep:
-
Select the part you want to keep.
-
Click Inverse Selection. Now everything except the part is selected.
-
Press Delete (Backspace on macOS) or click Delete Selected.
To keep the part as a separate object without deleting anything, use Selection to Object instead.
