Description
The Sketcher ConstrainDistanceX tool fixes the horizontal distance between two points or the endpoints of a line. If only one point is pre-selected, the distance is set to the sketch origin.
Usage
See also: Drawing aids.
Continue mode
- Make sure there is no selection.
- There are several ways to invoke the tool:
- Press the Constrain horizontal distance button.
- Select the Sketch → Sketcher constraints → Constrain horizontal distance option from the menu.
- introduced in version 0.22: Right-click in the 3D view and select the Dimension → Constrain horizontal distance option from the context menu.
- Use the keyboard shortcut: L.
- The cursor changes to a white cross with the tool icon.
- Do one of the following:
- Select two points (one of which can be the origin).
- Select a single line.
- If the Ask for value after creating a dimensional constraint option is selected (default) in the Sketcher Preferences:
- A pop up dialog opens to edit the constraint value.
- Press the OK button to confirm.
- A constraint is added.
- Optionally keep creating constraints.
- To finish, right-click or press Esc, or start another geometry or constraint creation tool.
Once-only mode
- Do one of the following:
- Select one or two points.
- Select a single line.
- Invoke the tool as explained above.
- Edit and/or confirm the constraint value as explained above.
- A constraint is added.
Scripting
Distance from origin:
Sketch.addConstraint(Sketcher.Constraint('DistanceX', Edge, PointOfEdge, -1, 1, App.Units.Quantity('123.0 mm')))
Distance between two vertices:
Sketch.addConstraint(Sketcher.Constraint('DistanceX', Edge1, PointOfEdge1, Edge2, PointOfEdge2, App.Units.Quantity('123.0 mm')))
Horizontal span of line (the GUI allows selecting the edge itself, but it is just a shorthand for using the two extremities of the same line):
Sketch.addConstraint(Sketcher.Constraint('DistanceX', Line, 1, Line, 2, App.Units.Quantity('123.0 mm')))
The Sketcher scripting page explains the values which can be used for Edge
, Edge1
, Edge2
, PointOfEdge
, PointOfEdge1
, PointOfEdge2
and Line
, and contains further examples on how to create constraints from Python scripts.
