Sketcher

Description

The Sketcher ConstrainDistanceX tool fixes the horizontal distance between two points or the endpoints of a line. If a single point is pre-selected, the distance is relative to the origin of the sketch.

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 1.0: If the Dimensioning constraints preference is set to Single tool (default): press the down arrow to the right of the button and select the Horizontal Dimension option from the dropdown.
   • If this preference has a different value (and in 0.21 and below): press the Horizontal Dimension button.
   • Select the Sketch → Constraints → Horizontal Dimension option from the menu.
   • introduced in 1.0: Right-click in the 3D View and select the Dimension → Horizontal Dimension option from the context menu.
   • Use the keyboard shortcut: L.
3. The cursor changes to a cross with the tool icon.
4. Do one of the following:
   • Select two points (one of which can be the origin).
   • Select a single line.
5. If a driving dimensional constraint is created, depending on the preferences, a dialog opens to edit its value.
6. A constraint is added.
7. Optionally keep creating constraints.
8. 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 one or two points.
   • Select a single line.
2. Invoke the tool as described above, or with the following additional option:
   • Right-click in the Elements section of the Sketcher Dialog and select the Horizontal Dimension option from the context menu.
3. Optionally edit the constraint value.
4. 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.
