Description

This tool is meant to aid in fully constraining a sketch by highlighting in green the sketch elements with remaining degrees of freedom (DoF).

Usage

1. In the Solver messages box located at the top of the Tasks tab, the following message should be displayed:

   Under-constrained sketch with X degrees of freedom

   where "X" is the number of degrees of freedom remaining in the sketch; click on the blue link, or use the menu.
2. The elements which have degrees of freedom are highlighted in green.
3. Click anywhere in the sketch to clear the highlight color.
