Add a Tangential Constraint

General

  • Surfaces and lines can be defined as tangential (i.e. adjacent) to each other.
  • The tangential side can be changed when adding the constraint or later.

Add a tangential constraint between parts

  1. Select Assembly | Constraints | Add Tangential Constraint, and select two parts, between which you add the constraint.
  2. Select the appropriate face or line on the first part.
  3. Select the appropriate face or line on the second part.
    • The parts will be positioned in accordance with the constraint.
  4. If the position of the parts is not satisfactory, you can select the function from the auxiliary menu: Flip previous constrain.
  5. Continue repeating steps 1 ... 4 until all the desired constraints have been added.
  6. Stop adding tangential constraints:
    • Select another function.
    • Press the Esc key.
    • Press the V key (Confirm).
    • Select the context-sensitive function OK.
    • Click the middle mouse button.

Change the side of a tangential constraint

  • You can change the side of a tangential constraint.
  1. Select the Tangent constraint in the lower frame of the assembly tree.
  2. Select Flip.

Example: tangentiality between a spherical surface and a cylindrical surface

Note:
  • You can also use this function by first selecting the two parts, and then
    • The ribbon bar function Add tangential constraint or
    • The context-sensitive function Constraints > Tangential.
    • Select the second part Ctrl+left mouse button.
  • If the result is not what you expected, you can flip the Tangential constraint. Flipp the Tangential Constraint
  • You can define a constraint as configuration-specific by selecting the constraint and then selecting the context-sensitive menu function Edit.

    Edit Constraint

  • Zoom the part view by the Z key to select an element. Zoom all by pressing the A key.
  • Move a part by moving the cursor onto a part, then moving the mouse while holding down the left mouse button.
