Automatic Solve
Specifies whether SolidWorks should automatically do the computation
to solve the sketch geometry of your part as you create it.
To turn automatic computation on or off:
Click Tools, Sketch Settings, Automatic
Solve. A check mark next to the menu item means that computations
are solved automatically.
NOTE: When
you are in the process of changing many dimensions in an active sketch,
you may want to turn off the Automatic
Solve option temporarily.
