Some AutoCAD commands

The following are some commands I use in AutoCAD.

• units --to setup units for your DWGs
• layer --to organize your DWGs' layers
  
• di --measure distance
• center --center of circle
• 3do --3D orbit for solid model watching
• shade --solid color on 3D DWGs
• from --starting point (when you draw a line)
• @ --refer to the point you just selected (otherwise, CAD will refer to the origin)
• < --drawing a line at an arbitrary angle. (When you're drawing a line at an unusual angle, you may want to see how the angle looks. After you specify the first point, you can type the < (angle) symbol and then the angle you want to try. For example, <10.
• google is always there for the rest :-)
