Description
The 
Sketcher ConstrainLock tool applies 
Horizontal distance and 
Vertical distance constraints to points. If a single point is selected the constraints reference the sketch origin. If two or more points are selected the constraints reference the last selected point.
Usage
See also: Drawing aids.
Continue mode
- Make sure there is no selection.
- There are several ways to invoke the tool:
- introduced in version 0.22: If the Dimensioning constraints preference is set to
Single tool(default): press the down arrow to the right of the
button and select the 
Constrain lock option from the dropdown. - If this preference has a different value (and in version 0.21 and below): press the Constrain lock button.
- Select the Sketch → Sketcher constraints → Constrain lock option from the menu.
- introduced in version 0.22: Right-click in the 3D view and select the Dimension → Constrain lock option from the context menu.
- Use the keyboard shortcut: K then L.
- introduced in version 0.22: If the Dimensioning constraints preference is set to
- The cursor changes to a cross with the tool icon.
- Select a single point.
- Two constraints is added.
- Optionally keep creating constraints.
- To finish, right-click or press Esc, or start another geometry or constraint creation tool.
Run-once mode
- Select one or more points.
- Invoke the tool as explained above.
- Depending on the selection two or more constraints are added.
Notes
- There is no automatic prompt to edit the constraint values. If required values can be edited manually.
