Copyright Goodheart-Willcox Co., Inc. 280 AutoCAD and Its Applications—Advanced Moving Faces When a face of a 3D solid is moved, all adjacent faces are dragged and stretched with it. The shape of the original 3D primitive or solid determines the manner in which the face can be moved and how adjacent faces react. A face can be moved using the MOVE command, 3DMOVE command, or move gizmo, or by dragging the face’s base grip. When moving a face, use the gizmo, polar tracking, or direct distance entry. Otherwise, the results may appear correct in the view in which the edit is made, but, when the view is changed, the actual result may not be what you wanted. See Figure 11-13. Parameter and base grips are displayed One base grip only A B Face is rotated Figure 11-12. A—This primitive is selected for editing. Notice the grips associated with the primitive. B—If the primitive is edited, the history of that primitive is deleted and a single base grip is displayed. A B C Figure 11-13. A—The original solid primitives. B—The box is dynamically edited without using exact coordinates or distances. C—When the viewpoint is changed, you can see that dynamic editing has produced unexpected results.
