First Box
Creates the datum reference value.
Second Box
Displays the
Material Condition dialog box (page 1097), 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.

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.
