Add a Tangential Constraint

General

  • The tangential constraint should only be added to two selected lines at a time.
  • The constraint can also be added to several arcs/circles, but the constraint is not added to "all possible places".
  • In sketch geometry, the symbol for the tangential constraint is a small circle .
    • You can use the F9 key to show and hide the symbols of the constraints.

Add a tangential constraint in a plane sketch

  1. Select the function Sketch | Constraints | Add tangential constraint.
  2. Select the first line.
    • This line remains in place unless the other line is locked in place with constraints.
  3. Select the second line.
    • This line moves so that it (or its extension) is tangent to the first line, unless the line is locked in place with constraints.
  4. Repeat steps 2 and 3 to add new tangential constraints
  5. Stop adding tangential constraints
    • Select another function or
    • press the V key or
    • press the Esc key or
    • click the middle mouse button.

Change the side of a the tangency

If the result was not what you expected, you can change the side of the tangential constraint after defining it.
  1. Select the tangential constraint from the list.
    • The program highlights the lines of the constraint.
  2. Select the Change side function from the context-sensitive menu.
