Using Automatic Solve

You can specify whether SOLIDWORKS uses automatic computation to solve the sketch geometry of a 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.
    When Automatic Solve is off, a message in the status bar says Auto-Solve Mode Off. When you are in the process of changing many dimensions in an active sketch, you must turn off the Automatic Solve option temporarily.

To control Automatic Solve and Undo:

Click Tools > Options > System Options > Sketch.
  • To disable the behavior of automatic turning off of Automatic Solve Mode and Undo, clear Turn off Automatic Solve Mode and Undo when sketch contains more than this number of sketch entities.
  • To modify the threshold limit, select Turn off Automatic Solve Mode and Undo when sketch contains more than this number of sketch entities and enter the input value in the input box.

Click OK.
