Chapter 5 Tolerancing & Templates
Perpendicularity tolerance (lines, cylinders, cones)
Use perpendicularity to establish an orientation tolerance between linear fea-
tures. Perpendicularity tolerancing compares the axial orientation of the se-
lected feature to the axis of a reference feature. The actual tolerance zone is a
cylindrical area around the axis of the tolerance feature. Specify the diameter of
the cylindrical tolerance zone to create the tolerance.
To perform a perpendicularity tolerance
Step 1
Highlight the desired feature in the features list.
NOTE
Use a linear features only. Perpendicularity tolerances do not
apply to other types of features.
Step 2
Click the perpendicularity button on the tolerance toolbar.
Step 3
Enter a value in the tolerance zone box as shown.
CAUTION
Enter tolerance values in the appropriate units of measurement.
For example, if you are measuring in metric (mm) enter tolerance
data in metric (mm).
