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

Add Coincident constraints to make sure the base length of the sketch-loop is equal to the length of the Part.

Note:

You can do Add Coincident Constraint between two Points*, a Line and a Point*, and two Lines.

* Point, start-Point, end-Point, center-Point.

STEP 1: Add Coincident Constraint: Point to Point

1.Expand the Constraints toolbar to the Right of the graphic-area

2.Click Constraints toolbar > Add Coincident

The pointer changes to Add Coincident.

3.Click the end-Point of the CAD-Line

4.Click the center-Point of the Arc to the right of the sketch

Note

The center-Point of Arcs (and Circles) are '+', and not 'o'.

When a center-Point is Coincident with a Point, the two Points in the graphic-area show as .

When a center-Point is Merged with a Point, the one Point in the graphic-area show as +.

STEP 2: Add Coincident Constraints: Point to Point

1.Click the center-point of the Arc near to the start-Point of the CAD-Line

2.Click the start-Point of the CAD-Line

STEP 3: Add Coincident Constraints: Point to Line

1.Click the center-point of the Arc at the top of the sketch-loop

2.Click the Y-axis

The image should be similar to the image to the left.
