Copyright Goodheart-Willcox Co., Inc. 278 AutoCAD and Its Applications—Advanced the Properties palette to change the color of edge and face subobjects or the material assigned to a face. The color of a subobject primitive can also be changed, but not the color of its subobjects. CAUTION CAUTION Use caution when using the SOLIDEDIT command with solid primitives and composite solids. The SOLIDEDIT command is discussed in Chapter 12. Using the SOLIDEDIT command with a solid primitive removes the history from the primitive. Do not use subobject editing methods if you plan on editing the solid primitive in the future. Once you use subobject editing on a primitive, the original geometric properties of the primitive cannot be edited with the Properties palette. The associated properties, such as the length, width, or height, are lost. Using the SOLIDEDIT command with a composite solid may remove some of the history from the solid. Therefore, the original objects—some of the subobjects—are no longer available for subobject editing. However, you may still be able to perform some subobject edits that will accomplish your design intent. PROFESSIONAL TIP PROFESSIONAL TIP The subobject fi lters help to quickly select the specifi c type of subobject. They are located in the Selection panel on the Home, Solid, and Mesh tabs of the ribbon. The subobject fi lters can also be selected from the Filters object selection fl yout on the status bar. This fl yout does not appear on the status bar by default. Select the Selection Filtering option in the status bar Customization fl yout to add the Filters object selection fl yout to the status bar. When a subobject fi lter is active, an icon representing the fi lter appears next to the crosshairs. Subobject fi lters are introduced in Chapter 9. Subobject Editing Fillets and Subobject Editing Fillets and Chamfers Chamfers If you improperly create a fi llet or chamfer, edit it by holding down the [Ctrl] key and selecting the fi llet or chamfer. Then, use editing methods to change the fi llet or chamfer. If the solid history has been recorded, a fi llet has a parameter grip that can be used to change the radius of the fi llet and a chamfer has parameter grips that can be used to change the chamfer distances. On some occasions when editing fi llets or chamfers, the fi llet radius or the chamfer distances will not appear in the Properties palette. If this is the case and you only see a single face grip on the surface of the fi llet or chamfer, erase the fi llet or chamfer and reapply it. Fillet and chamfer subobject editing is a form of composite solid editing. PROFESSIONAL TIP PROFESSIONAL TIP The Delete option of the SOLIDEDIT command deletes selected faces. This is a quick way to remove features such as chamfers, fi llets, holes, and slots. This technique is discussed in Chapter 12.
