Examples of the use of the Extrude tool

The fi rst two examples of forming regions given in Figs 12.10 and 12.11
are used to show the results of using the Extrude tool.

First example - Extrude ( Fig. 12.13 )

From the fi rst example of forming a region:

1. Open Fig. 12.10. Erase all but the region 2 .
2. Make layer Green current.
3. Call Extrude (Fig. 12.12). The command line shows:

Command: _extrude
Current wire frame density: ISOLINES=4
Closed profi les creation mode=Solid

Select objects to extrude or [MOde]: pick region
1 found
Select objects to extrude or [MOde]: right click
Specify height of extrusion or [Direction/Path/
Taper angle /Expression ] <45>: enter 50 right-
click
Command:

4. Place in the Layers & View/3D Navigation/SW/Isometric view.
5. Call Zoom and zoom to 1 .
