### Location Axes

This table describes the available Location Axes and their functions that you can choose from while editing dimension information.

Worst | This option uses the axis that gives the worst out of tolerance condition. PC-DMIS searches through the available axes and selects the one that gives the worst case scenario for the dimension.
Use Dim Axes | This option simply uses the axes that were previously defined in the dimension's dialog box.
X | Displays the X axis value.
Y | Displays the Y axis value.
Z | Displays the Z axis value.
Prad | Prad stands for Polar Radius. This option selects Polar coordinates.
Pang | Pang stands for Polar Angle. This option selects Polar coordinates.
D | Displays Diameter value.
R | Displays the Radius (half of Diameter) value.
A | Displays the Angle (for cones) value.
L | Displays the Length (used for cylinders, slots, cones, and ellipses).
H | Displays the height.
V | Displays the vector location.
T | Displays error along approach vector (for points on curved surfaces).
RT | Displays the deviation along the report vector.
S | Displays the deviation along the surface vector.
RS | Displays the deviation along the surface report vector.
PD | Displays the diameter of a circle (perpendicular to the pin vector).
Form | Displays the integrated form dimension for the feature. See "Default Axes for Location Dimensions" in the "Dimensioning Features" section.
