Sym

Displays the geometric characteristic symbol, which you select from the Symbol dialog
box. The dialog box is displayed when you select one of the Sym boxes.

Tolerance 1

Creates the first tolerance value in the feature control frame. The tolerance value
indicates the amount by which the geometric characteristic can deviate from a perfect
form. You can insert a diameter symbol before the tolerance value and a material condition
symbol after it.

First Box

Inserts a diameter symbol in front of the tolerance value. Click the box to insert
the diameter symbol.

Second Box

Creates the tolerance value. Enter a value in the box.

Third Box

Displays the Material Condition dialog box, in which you select a modifying symbol.
These symbols act as modifiers to the geometric characteristic and the tolerance value
of features that can vary in size.

The symbol is inserted into the MC box for the first tolerance value in the Geometric
Tolerance dialog box.

Tolerance 2

Creates the second tolerance value in the feature control frame. Specify the second
tolerance value in the same way as the first.

Datum 1

Creates the primary datum reference in the feature control frame. The datum reference
can consist of a value and a modifying symbol. A datum is a theoretically exact geometric
reference used to establish the tolerance zone for a feature.

First Box

Creates the datum reference value.

Second Box

Displays the Material Condition dialog box, in which you select a modifying symbol.
These symbols act as modifiers to the datum reference.

The symbol is inserted into the MC box for the primary datum reference in the Geometric
Tolerance dialog box.

Datum 2

Creates the secondary datum reference in the feature control frame in the same way
as the primary datum reference.

Datum 3

Creates the tertiary datum reference in the feature control frame in the same way
as the primary datum reference.

Height

Creates a projected tolerance zone value in the feature control frame. A projected
tolerance zone controls the variation in height of the extended portion of a fixed
perpendicular part and refines the tolerance to that specified by positional tolerances.

Projected Tolerance Zone

Inserts a projected tolerance zone symbol after the projected tolerance zone value.

Datum Identifier

Creates a datum-identifying symbol consisting of a reference letter. A datum is a
theoretically exact geometric reference from which you can establish the location
and tolerance zones of other features. A point, line, plane, cylinder, or other geometry
can serve as a datum.
