KNOW THE VIEWCUBE
Throughout the following exercise, you'll make heavy use of the ViewCube. Make sure you are
familiar with how it works. If you need a refresher, see Chapter 19.
Start by creating a new drawing and setting up the parameters for the mesh.
1.
Choose File
New from the menu bar (or press F-N), select acad3D.dwt, and then click
Open. Metric users can select the acadiso3D.dwt file.
2.
Choose the Shaded With Edges visual style from the Visual Styles menu on the Viewport
Controls.
3.
Type
DIVMESHBOXWIDTH
↵
4
↵. This sets the mesh division for the box width to four
faces instead of the default three.
4.
Type
DIVMESHBOXLENGTH
↵
4
↵. This sets the mesh division for the box mesh length
to four faces instead of the default three.
5.
Finally, type
DIVMESHBOXHEIGHT
↵
1
↵. This sets the mesh division for the box mesh
height to one face instead of the default three.
The parameters you change alter the number of faces on mesh primitives that you create,
including the box primitive in the next exercise. You'll see the results in the next set of steps:
1.
Type
MESH
↵
B
↵ to create a primitive mesh box.
2.
At the Specify first corner or [Center]: prompt, type
0,0
↵ to start the corner at the
origin of the drawing.
3.
At the Specify other corner or [Cube/Length]: prompt, enter
50,30
↵ to create
a 50˝-
×
-30˝ base for the box. Metric users can enter
1270,762
↵.
4.
At the Specify height or [2Point] prompt, point the cursor in the positive Z direction
and then enter
3.5
↵ for a 3.5 units thickness. Metric users enter
88.9
↵.
5.
Center the box in your view.
6.
Click the mesh box to select it. On the Properties Inspector palette, click the Smoothness
drop-down list in the Geometry group. Select Level 4. Your mesh box is now smoothed
again as it was originally. Your model should look similar to Figure 23.4.
