Select faces, edges, and vertices on 3D objects.

A subobject is a face, edge or vertex of a solid, surface, or mesh object.

Select Subobjects

To select a face, edge, or vertex of a 3D object, press Ctrl as you select the object. (If you have set a subobject filter, you do not need to press Ctrl first.)

Selected subobjects display different types of grips, depending on the subobject type.

You can select one or more subobjects on any number of 3D objects. The selection set can include more than one type of subobject. Press Ctrl to select subobjects at the selection prompts of the MOVE, ROTATE, SCALE, and ERASE commands.

You can remove an item from the selection set by pressing the Shift key and selecting it again.

Select Subobjects on Composite 3D Solids

Press and hold Ctrl to select faces, edges, and vertices on composite solids. If the History property of the composite solid is set to Record, the first “pick” might select the history subobject. (The history subobject is the portion of the original object that was removed during the union, subtract, or intersect operation.) Continue to hold down Ctrl and pick again to select a face, edge, or vertex on the original form.

If you set a subobject selection filter, you can select the face, edge, or vertex by clicking it once.
