Coincident Constraint

Sketcher

Description

The Sketcher ConstrainCoincidentUnified tool creates a coincident constraint between points, fixes points on edges or axes (lines are then treated as infinite, and open curves are virtually extended as well), or creates a concentric constraint between circles, arcs and/or ellipses (by making their centers coincident).

This tool replaces the Sketcher ConstrainCoincident and Sketcher ConstrainPointOnObject tools if the Unify coincident and point-on-object constraints option is selected in the preferences.

Usage

See also: Drawing aids.

Continue mode

1. Make sure there is no selection.
2. There are several ways to invoke the tool:
   • Press the Coincident Constraint button.
   • Select the Sketch → Constraints → Coincident Constraint option from the menu.
   • Right-click in the 3D View and select the Constrain → Coincident Constraint option from the context menu.
   • Use the keyboard shortcut: C.
3. The cursor changes to a cross with the tool icon.
4. Do one of the following:
   • Select two points.
   • Select two edges of circles, arcs, ellipses or arcs of ellipses.
   • Select a single point and a single edge (in any order).
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 two or more edges of circles, arcs, ellipses or arcs of ellipses.
   • Select a single point and a single edge (in any order).
   • Select several points and a single edge (idem).
   • Select a single point and several edges (idem).
2. Invoke the tool as described above, or with the following additional option:
   • Right-click in the 3D View and select the Coincident Constraint option from the context menu.
3. Depending on the selection one or more constraints are added.
