Add Tangent

Toolbar-ConstraintsTangent

Toolbar:

Right-side of the graphics-area

Menu:

Add menu > Geometry sub-menu> > Constraints sub-menu > Add Tangent

What to do:
1.Click Constraints toolbar > Add Tangent
2.Click:
•Two Circles ; or two Arcs ; or one Circle and one Arc.

- or -

•A Line and a Circle ; or a Line and an Arc

- or -

•A Circle or Arc and the Part's X–axis or Y–axis

Notes

element '1' must remain red when you click the element '2'. If it is not, click element 1 again.

A CAD-Line is a Line.

Result:
•The two Circles or two Arcs become Tangential

- or -

•The Line and Circle or Arc become Tangential

- or -

•The Circle or Arc becomes Tangential with the X–axis or the Y–axis

Notes:
•MechDesigner treats Arcs and Circles in the same way.
•If possible, drag a point of one of the sketch-elements to be near to tangential before you use this command.
•It is not possible to add an 'Internal' tangent constraint.
