To set up your file
1 Open the file t_surfs.dwg in the desktop\tutorial folder. The wireframe objects
you need for this lesson are included in this file.
NOTE Back up the tutorial drawing files so you still have the original files if you
make a mistake. See Backing up Tutorial Drawing Files on page 40.
Surface lines, called U and V lines, indicate the direction of the surface.
Increasing the number of lines increases the density of the surface image.
2 Use the Mechanical Options dialog box to change the number of surface
lines used to display surfaces.
Desktop Menu Surface Surface Options
Choose the Surface tab, and in Surface Properties specify:
U Display Wires: Enter 7
V Display Wires: Enter 7
Choose OK.
NOTE If you shade the surfaces you create to better view them, adjust the
AutoCAD setting that controls back faces. Go to Assist Options and select the
System tab. Choose Properties, then clear the check box for Discard Back Faces.
Choose Apply & Close, then OK.
You are ready to create your first surfaces.
