Getting Started Tutorials - MechDesigner > Tutorial 3: Add a Sketch-Loop to a Part

We add Coincident Constraints to make sure the length of the sketch-loop is equal to the length of the Part.

GA-AddCoincident-2Pts

Where is the Coincident Constraints icon?

Right of graphic-area in the Part-Editor:

Constraints toolbar > Add Coincident

STEP 1: Click Constraints toolbar >Add Coincident

In the graphic-area:

STEP 2: Click the center-Point of the Arc to the right of the sketch

See image

STEP 3: Click the end-Point of the CAD-Line

GA-AddCoincident-2PtsB

Notice, in the image above, that the Points at the center of Arcs (and Circles) are '+', and not 'o'.

When the Points are Coincident, the two Points : ''.

When the Points become Merged, the one Point: '+'.

GA-AddCoincident-C

Do Add Coincident Constraint again with the other two arcs in the sketch-loop.

Coincident: Point to Point

STEP 4: Click the center-point of the Arc near to the start-Point of the CAD-Line and the start-Point of the CAD-Line

Coincident: Point to Line, X-axis or Y-axis

STEP 5: Click the center-point of the Arc and the vertical Y-axis

The center-point of each Arc is coincident with the start-Point of the CAD-Line and the Y-axis.
