### Constructing a High Point Plane

PC-DMIS is only able to construct a High Point Plane from a set of features. The set must contain at least three features. | A High Point plane can be constructed using features forming a set or a patch scan. To construct a High Point Plane:

1. Access the Construct Plane dialog box (Insert | Feature | Constructed | Plane).

2. Select the High Point option.

3. Select three or more features (any feature type may be used). A set using at least three features or a patch scan can also be used. See "Constructing a Set of Features" or "Performing a Patch Advanced" in the "Scanning Your Part" section.

4. Click the Create button.

5. First, PC-DMIS will construct a Best Fit plane from the input features. Next, PC-DMIS rotates to the Best Fit plane. It then finds the highest three points on this plane (from the selected features) and uses them to create the high point plane.

The centroid of the input features used to construct the high point plane defines the center of gravity. PC-DMIS automatically creates a second plane if the first high point plane doesn't include the center of gravity.

The Edit window command line for this option would read:
CONSTR/PLANE, HIPNT,feat_1, feat_2, feat_3, . . .
