Sketcher Dialog/zh-cn

Introduction
While a sketch is being edited, or, in other words, while a sketch is in edit mode, the Sketcher Dialog is displayed on the Task tab of the Combo view.

To put a sketch in edit mode do one of the following:
 * Double-click the sketch in the Tree view.
 * Right-click the sketch in the Tree view and select from the context menu.
 * Select the sketch and press the button.
 * Select the sketch and then select the option from the menu.

The dialog consists of the following sections:

Solver messages
This section informs about the state of the sketch. A sketch can be under constrained, fully constrained or have redundant constrains.

If a sketch is under constrained the number of degrees of freedom (or Dofs) is indicated. Clicking this text will select the under constrained sketch elements.

If a sketch has redundant constraints the indices of the constraints are indicated. Clicking that text will select these constraints.

Available options:

Advanced solver control
This section will only appear if you check the Show section 'Advanced solver control' option in the sketcher preferences.

Note that most of the options in this section are of no practical use. They can however help with testing and understanding the solvers.

Available options:

Constraints
This section lists the constraints in the sketch. Unchecking a constraint in the list will hide it in the sketch. Constraints can be selected in the list as well as in the sketch.

Available options:

Elements
This section lists the elements in the sketch. Unchecking an element in the list will hide it in the sketch. Elements can be selected in the list as well as in the sketch.
