To Add a Constraint to a Model in Part Builder

The procedure below uses the example of aligning the top and bottom faces of a rectangular shaped part.

  1. In the part browser, right-click XY Plane and click Add GeometryPoint.
  2. In the modeling area, specify a point near the center of the top face rectangular profile and press Enter.
  3. In the part browser, right-click XY Plane and click Add ConstraintsEqual Distance.
  4. In the modeling area, specify the pairs of geometric constraints.
  5. For the first pair, select the point in the center of the top face, and then the lower-left edge of the top face rectangular profile.
  6. For the second pair, select the point in the center of the top face, and then the upper-right edge of the top face rectangular profile.

    The model of the top face is updated to the specified constraint.

  7. Repeat steps 3 and 4 to constrain the upper-left and lower-right edges of the top face.

    The model of the top face is updated to the specified constraint.

    Note: When adding constraints, you may be prompted that the geometry is unconstrained by a specific number of dimensions. These prompts are for informational purposes only to assist you during the modeling process. It is recommended that you add a minimum number of constraints to define the shape of the part to avoid undesirable results.
  8. To ensure the alignment of the top and bottom faces, in the part browser, right-click Bottom Face and click Add GeometryPoint Reference.
  9. Select the existing point in the center of the top face rectangular profile.

    A reference point is added to the bottom face work plane.

  10. Repeat steps 3 through 5 to constrain all four edges of the bottom face using the reference point in the center of the bottom face.

    The model of the bottom face is updated to the specified constraints.
