Description

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 parallel button.
   • Select the Sketch → Sketcher constraints → Constrain parallel option from the menu.
   • introduced in version 1.0: Right-click in the 3D view and select the Constrain → Constrain parallel option from the context menu.
   • Use the keyboard shortcut: P.
3. The cursor changes to a cross with the tool icon.
4. Select two lines.
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.

Run-once mode

1. Select two or more lines. introduced in version 1.0: Points can be included in the selection, but will be ignored.
2. Invoke the tool as explained above, or with the following additional option:
   • introduced in version 1.0: Right-click in the 3D view and select the Constrain parallel option from the context menu.
3. Depending on the selection one or more constraints are added.

Scripting

Sketch.addConstraint(Sketcher.Constraint('Parallel', Line1, Line2))

The Sketcher scripting page explains the values which can be used for Line1 and Line2 and contains further examples on how to create constraints from Python scripts.
