Delete Selected removes the selected triangles from meshes and the selected points from point clouds. Use it to cut away scan noise, a stand or a fixture captured with the part, or any other area you do not need.
Delete the selected area
- Select the triangles or points to remove, for example with Select Primitives, Select Region or Select Component.
- Click Select › Delete Selected, or press Delete (Backspace on macOS).
The command works at once on all objects selected in the Scene Tree: the selected triangles of every selected mesh and the selected points of every selected point cloud are removed, and the selection is cleared. Nothing happens if none of the selected objects has a selection.
The same button is on the Points tab and on the toolbar above the viewport. If Select Primitives is open, it stays open, so you can select and delete the next area.
Undo a deletion
The deletion is not final: press Undo (Ctrl+Z, or Cmd+Z on macOS) to get the triangles or points and the selection back.
Close the hole after deleting triangles
When you delete triangles from a closed surface, an opening with an open boundary remains where they were.
To make the surface closed again, fill the opening with Fill Holes. If you painted the selection in Select Primitives with Select Back Triangles on, triangles facing away from you under the brush or lasso were selected too and are deleted as well; check the far side of the model before you delete.
To keep one part and delete everything else, select the part, use Inverse Selection, and then Delete Selected. To keep the selected part as a separate object instead, use Selection to Object.
