All parameters are displayed, including theta values and sketch dimensions. Press exit to leave edit mode, or click a value to open the Dimension Dialog. In this dialog you can enter another value, or enter an equation involving parametric dependency.
When the parameters are updated, click

the feature, or you can update it later. (If you do not update now, all
