Select Patches and Elements

Select a patch by clicking on it in the 2D View or the 3D View with the Select Tool. Select multiple patches by dragging from an empty area in the 2D View to make a selection box. All patches touched by the box are selected.

Select all patches by choosing Edit > Select All (Command-A). Deselect all patches by clicking on any empty area.

To add new patches to the current selection, hold down the shift key while clicking or dragging. To subtract selected patches from the selection, hold down the option key.

To select edges and flaps, just switch to the Subselect Tool and perform the same operation.
