1.6 Constructing Part Features
Constructed features
New features can be constructed from probed, created, or other
constructed features in 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.
Constructing features
The method of constructing a feature is identical for all feature types.
To construct a feature:
Press the desired feature Measurement key
Press the Constr soft key or the Up Arrow key
Highlight a required parent feature, then press the ENTER key to
select it
Continue highlighting and selecting parent features until all the
required features are selected
Press the FINISH key
Notice
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”.
Notice
An example of constructing a feature is shown on the next
page.
