Alignment with Offset Plane

The offset plane can be used in an alignment construction. A good example of an offset plane is cast datum points, where they are rarely on the same plane.

Offset Plane

The first step is to probe 3 Space Points on the model at different heights. If you have a CAD model change the feature type selection to Define a Space Point and place 3 points on the model at different heights, i.e. the cast datum points.

Click on the Edit button at Point Modification

Point A1 in our example is at 0

·        Enter 0 in Point 1

·        Enter -10.00 in Point 2

·        Enter -8.00 in Point 3

This is the method to create an offset plane. It can now be used in a Base Alignment, or as you would any feature.
