Use Snap Modes in Arithmetic Expressions
You can use Snap modes as parts of arithmetic expressions. The program
prompts you to select an object and returns the coordinate of the appropriate
snap point. Using arithmetic expressions with Snap modes greatly simplifies
entering coordinates relative to other objects.
When you use these Snap modes, enter only the three-character name. For
example, when you use the Center Snap mode, enter cen. CAL Snap modes
set the value of the
LASTPOINT (page 1344) system variable.
