Using Auto Dimension Scheme, you can specify
one of two part types, Prismatic or Turned.
This option affects the annotation views and leader options used to display diameter
dimensions. With geometric tolerancing, the option also affects the type of tolerances used
to locate features that are concentric to a datum axis.
Prismatic Parts
Diameter dimensions are displayed with a directed leader in an
annotation view that is perpendicular to the feature’s
axis.
Position tolerances are used to locate features that are concentric
with a datum axis. The tolerances applied to the 41.50, 50.20, and 80 diameters are
position tolerances. They are concentric with the axis of datum
B.
Turned
Diameter dimensions are displayed in an annotation view as linear
dimensions that are parallel to the feature’s
axis.
Runout tolerances are used to locate features that are concentric
with a datum axis. The tolerances applied to the 41.50, 50.20, and 80 diameters are
runout tolerances. They are concentric with the axis of datum
B.
