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 0.22: 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 0.22: 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 horizontally option from the dropdown.
    • If this preference is not selected (and in version 0.21 and below): press the Constrain horizontally button.
    • Select the Sketch → Sketcher constraints → Constrain horizontally option from the menu.
    • Use the keyboard shortcut: H.
  3. The cursor changes to a white 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:
  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.
