Profile
The profile tolerance can be applied to profile features and is used to specify the acceptable material
deviation outside and inside the nominal part profile. Tolerances can be specified as bilateral (equal) or as
non-bilateral (unequal).
Equal bilateral tolerances
Bilateral tolerance zone will be centered around the edges of the nominal profile. For example, an equal
bilateral tolerance of 0.005 will be
applied as ±0.0025.
Check the Bilateral box and enter
the desired tolerance value into
the Tolerance data field for equal
bilateral tolerances.
Unequal tolerances
Unequal bilateral or unilateral tolerance values are specified by the user for In-material tolerance and Out-
material tolerances. This example
shows a boss with different In-ma-
terial and Out-material tolerances.
Clear the Bilateral box and enter
the desired In-material and Out-
material tolerance values in the
data fields provided.
Click OK to apply the profile tolerances.
An equal bilateral tolerance of 0.005 is applied as... ±0.0025
Unequal bilateral tolerances are applied as... +0.003 and - 0.001
