Creating additional Plane constraints
 
 
 

A top view reveals an illogical placement of the fence locators. Instead of being aligned with the XY plane, they are at an angle. To correct this problem, you need another Plane constraint that represents the fence.

To create a Plane constraint using the fence locators

  1. Click the Survey option to switch to the Survey settings.
  2. Make sure the Constraint Type is still set to Plane.
  3. Select the following track points in the Outliner under clip1TrackedPointVisibilityGroup > clip1TrackedPointGroup:

    These are the points that are on the front of the fence.

  4. Click Create.
  5. Change the Name setting to fence.
  6. In the Channel Box, rotate the fence plane by entering 90 in the Rotate X attribute. Because the real fence is at a 90 degree angle to the backyard ground, you must rotate the fence constraint the same way in Maya.

    In this case, only the plane’s rotation matters, not where you move it. No matter where you move the fence Plane constraint, the fence points will remain on the grid because the solver must obey the ground constraint you created.

    The scale of the Plane constraint never matters because the solver treats it as infinitely large.

  7. Switch to the Solve control panel, select registered from the solution list, and click the Register button. The solver creates registered1 with the fence points aligned with the XY plane.
