Add a Concentricity Constraint

General

  • It is possible to add a concentricity constraint between two cylindrical or conical surfaces, for example.
  • Cylindrical or conical surface and a line (segment).
  • Cylindrical or conical surface and a point.
  • Two lines (segments), although in this case it is worth using the coincidence constraint for the sake of clarity.
  • A line (segment and point), although in this case it is worth using the coincidence constraint for the sake of clarity.
  • Spherical surfaces and torus surfaces can also be used as parties to concentricity constraints.

Add a concentricity constraint between parts

  1. Select Assembly | Constraints | Add concentricity constraint.
  2. Select a face, line, or a point from the first part.
    • The face can be a planar face, cylindrical face, spherical face or torus face.
  3. Select a face, line, or a point the second part.
    • The program moves the parts to the location defined by the constraint.
  4. If the position of the parts is not satisfactory, you can select the function from the auxiliary menu: Flip previous constrain.
    • The auxiliary function is possible if the elements of the constraint are of the type: Cylindrical or conical surface, circle or straight line.
  5. Continue repeating steps 1 ... 4 until all the desired constraints have been added.
  6. Stop adding concentricity constraints:
    • Select another function.
    • Press the Esc key.
    • Press the V key (Confirm).
    • Select the context-sensitive function OK.
    • Click the middle mouse button.
Note:
  • You can also use this function by first selecting the two parts, and then
    • The ribbon bar function Add concentricity constraint or
    • The context-sensitive function Constraints > Concentricity.
    • Select the second part Ctrl+left mouse button.
  • 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.
