Sketcher ConstrainHorizontal/sv

Horizontal/vertical

Vertical

Sketcher

Description

The Sketcher ConstrainHorizontal tool constrains lines or pairs of points to be horizontal (parallel to the horizontal axis of the sketch).

introduced in version 1.0: In most cases it is advisable to use the combined Sketcher ConstrainHorVer tool instead.

Usage

See also: Drawing aids.

Continue mode

1. Make sure there is no selection.
2. There are several ways to invoke the tool:
   • introduced in version 1.0: If the Auto tool for Horizontal/Vertical preference is selected (default): press the down arrow to the right of the button and select the Constrain horizontal option from the dropdown.
   • If this preference is not selected (and in version 0.21 and below): press the Constrain horizontal button.
   • Select the Sketch → Sketcher constraints → Constrain horizontal option from the menu.
   • Use the keyboard shortcut: H.
3. The cursor changes to a cross with the tool icon.
4. Do one of the following:
   • Select two points.
   • Select a single line.
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. Do one of the following:
   • Select two or more points.
   • Select one or more lines. 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 horizontal option from the context menu.
3. Depending on the selection one or more constraints are added.

Scripting

Sketch.addConstraint(Sketcher.Constraint('Horizontal', Line))

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