Description

The Sketcher ConstrainEqual tool constrains edges to have an equal length (lines) or curvature (other edges except B-splines). Selected edges must have the same type. Circles and circular arcs are of the same type (their radii are made equal), and so are ellipses and elliptical arcs (their major and minor radii are made equal).

Usage

See also: Drawing aids.

Continue mode

  1. Make sure there is no selection.
  2. There are several ways to invoke the tool:
    • Press the Constrain equal button.
    • Select the Sketch → Sketcher constraints → Constrain equal option from the menu.
    • introduced in version 0.22: Right-click in the 3D view and select the Constrain → Constrain equal option from the context menu.
    • Use the keyboard shortcut: E.
  3. The cursor changes to a white cross with the tool icon.
  4. Select two edges of the same type.
  5. A constraint is added.
  6. Optionally keep creating constraints.
  7. To finish, right-click or press Esc, or start another geometry or constraint creation tool.

Once-only mode

  1. Select two or more edges of the same type.
  2. Invoke the tool as explained above.
  3. Depending on the selection one or more constraints are added.

Scripting

Sketch.addConstraint(Sketcher.Constraint('Equal', Edge1, Edge2))

The Sketcher scripting page explains the values which can be used for Edge1 and Edge2 and contains further examples on how to create constraints from Python scripts.
