Each BaseFeature element identifies a base feature to be used for the construction of an extruded cross section. The number of base features must be 6 or greater.

The ExtrudedCrossSectionBestFitType defines the information for a best-fit extruded cross section which includes a list of point-reducible base features; the points to which those features reduce are used in the best-fit construction of the extruded cross section.
The required n attribute is the number of base features used in the construction.
