Step 3.4: Add Coincident Constraints

Summary of the Step

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

Add Coincident relationships

GA-AddCoincident-2Pts

Icon-SE-Coincident Where is the Coincident Constraints icon?

Right of graphic-area in the Part-Editor:

Constraints toolbar > Add Coincident Red-14-3


STEP 1: Click Constraints toolbar >Add CoincidentRed-14-3

In the graphic-area:

STEP 2: Click the center-PointRed-14-2 of the Arc to the right of the sketch

See image

STEP 3: Click the end-PointRed-14-1b of the CAD-Line

GA-AddCoincident-2PtsB


Notice, in the image above, that the Points at the center of ArcsRed-14-2 (and Circles) are '+', and not 'o'.

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

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.
