This constraint tool takes two points as its argument and serves to make the two points ''coincident''. (Meaning to make them as-one-point). |

In practical terms this constraint tool is useful when there is a break in a profile for example - where two lines end near each other and need to be joined - a coincident constraint on their end-points will close the gap. |

Description
The Sketcher ConstrainCoincident tool creates a coincident constraint between points, or (introduced in version 0.21) a concentric constraint between circles, arcs and/or ellipses (by making their centers coincident).
introduced in version 1.0: This tool is replaced by the Sketcher ConstrainCoincidentUnified tool if the Unify Coincident and PointOnObject option is selected in the preferences.
Usage
See also: Drawing aids.
Continue mode
- Make sure there is no selection.
- There are several ways to invoke the tool:
- Press the Constrain coincident button.
- Select the Sketch → Sketcher constraints → Constrain coincident option from the menu.
- Use the keyboard shortcut: C.
- The cursor changes to a cross with the tool icon.
- Do one of the following:
- Select two points.
- Select two edges of circles, arcs, ellipses or arcs of ellipses.
- A constraint is added.
- Optionally keep creating constraints.
- To finish, right-click or press Esc, or start another geometry or constraint creation tool.
Run-once mode
- Do one of the following:
- Select two or more points.
- Select two or more edges of circles, arcs, ellipses or arcs of ellipses.
- Invoke the tool as explained above.
- Depending on the selection one or more constraints are added.
Notes
- introduced in version 1.0: Points with Coincident constraints are marked with the Constraint symbols color.
Scripting
The constraint can be created from macros and from the Python console by using the following command:
Sketch.addConstraint(Sketcher.Constraint('Coincident',LineFixed,PointOfLineFixed,LineMoving,PointOfLineMoving))
where :
Sketch
is a sketch objectLineFixed
is the number of the line, that will not move by applying the constraintPointOfLineFixed
indicates which vertex ofLineFixed
has to fulfill the constraintLineMoving
is the number of the line, that will move by applying the constraintPointOfLineMoving
indicates which vertex ofLineMoving
has to fulfill the constraint
As the names LineFixed
and LineMoving
indicate, if both constrained vertices are free to move in any direction, the first one (first to be selected in the Gui) will remain fixed and the other one will move. In the presence of existing constraints, however, both edges may move.
The Sketcher scripting page explains the values which can be used for LineFixed
, PointOfLineFixed
, LineMoving
and PointOfLineMoving
, and contains further examples on how to create constraints from Python scripts.
