Build Geometry

1.  Define keypoints.

To take advantage of symmetry in this problem, model only half of the "L."  First, construct the trapezoid representing the outline of the mold by defining the four corner points of the trapezoid and then defining an area connecting these four keypoints.

Remove the global triad symbol so that it won't obscure the view of the keypoint at the origin.
