To Select Entities
Use the following methods for selecting geometry when the Style tab is open:
To select an object, click it.
To select multiple objects, hold down the CTRL key while you click objects.
To clear the selection of an object that is selected, hold down the CTRL key and click it.
To clear the selection of all objects, click anywhere in the graphics window except the object or objects.
For example, if you want to delete multiple surfaces, hold down the CTRL key, click each surface, and press the DELETE key to delete all selected surfaces.
Using Selection to Move and Copy Curves
Use the following shortcuts to move and copy curves without translating, scaling, or rotating them:
To move a selected curve freely, drag it.
To move a selected curve along the normal of the active datum plane, hold down the ALT key while you drag the curve.
To move a selected curve parallel to the active datum plane either along the horizontal direction only or along the vertical direction only, hold down the CTRL and ALT keys simultaneously while you drag the curve.
To copy a selected curve, hold down the CTRL key and drag the curve. The copy is always linked to the original geometry that is being copied.
