The Scale submode allows you to manually scale sections of subdivisions and some other 3D objects along a line or plane.
To scale an entire object, see Scaling objects.
To scale a section of a subdivision or other 3D object:
Select the object with a section to scale.
Click the tool and mode.
Click Scale submode, and either Align to Object or Align to Working Plane mode.
As you move the cursor over the object, entities are highlighted to indicate they can be scaled.
For NURBS curves, NURBS surfaces, and 3D polygons, vertices can be scaled.
For subdivision objects, the cage mesh's edges, faces, and vertices can be scaled.
Click a highlighted entity to place the Scale 3D dragger; to select multiple entities at one time, Shift-click, or Shift-drag to create a marquee selection. For multiple selections, the 3D dragger is placed in the center relative to the selected entities and oriented to the current working plane, regardless of which alignment mode is selected.
The Scale 3D dragger displays. See Repositioning the 3D dragger if needed.
Click the 3D dragger's appropriate linear or planar control and move the dragger to scale.
The selected entities are highlighted, and the active control displays in yellow during the operation. Depending on the selected control, a projection line or plane indicator displays to indicate the available movement. As you move the dragger, the change previews. The 3D dragger moves differently depending on the alignment mode and dragger control selected.
Subdivision objects have the following additional behaviors:
To scale a subdivision uniformly in all directions, press the Alt key during the operation.
Selected cage mesh entities, and the corresponding section of the subdivision model, are completely deleted from the drawing if you press the Delete key while in Transform mode; deleting a face in this way creates the open edges required for some subdivision edits. Deleted cage mesh and model faces can be restored (see Bridging open edges of a subdivision model or Closing a hole in a subdivision model). A face of the subdivision model can be removed in such a way that it can be added back to the model later (see Making a hole in a subdivision model).
Click to complete the scale operation. The 3D dragger remains in place, to facilitate another reshape.
