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 PointOnObject 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 Constrain coincident button.
    • Select the Sketch → Sketcher constraints → Constrain coincident option from the menu.
    • Right-click in the 3D view and select the Constrain → Constrain coincident 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 explained above, or with the following additional option:
    • Right-click in the 3D view and select the Constrain coincident option from the context menu.
  3. Depending on the selection one or more constraints are added.
