1.6 Constructing Part Features

Constructed features

New features can be constructed from probed, created, or other
constructed features from the features list. Constructions are
frequently used to perform skew alignments, set datums and
measure relationships between parent features.
Users can construct points, lines, circles, distances, angles, and part
skews. Constructed features are the same as probed features. They
can have form errors and tolerances can be applied.
If a construction is requested that does not include the
required parent features or is not supported, an error
message is displayed indicating an "Invalid construction".
