The next two exercises will demonstrate how to apply a multiple single-segment tolerance
and a composite tolerance using the same model.
Open the Position - Rectangular Pattern document. Some datums and a dimension
already exist.
Select the Tolerancing Advisor icon. The Semantic Tolerancing Advisor window
appears.
Select A|B|C in the window, then select the .3750 dimension. The window expands.
Select the Position-with-DRF Specification icon. The Geometrical Tolerance
window appears.
Change the Numerical value to 0.02 and select the Maximum Material Condition icon.
Select OK , then select Close . The tolerance appears. This is the same as what you did
earlier.
Next, you will create a multiple single-segment tolerance of position. The upper segment
controls the location of the hole pattern in reference to the datums. The lower segment
controls the spacing and orientation of the pattern and the location of the pattern.
Select the Tolerancing Advisor icon again. The Semantic Tolerancing Advisor
window appears.
Select A|B in the window, then select the positional tolerance and pick the Position-
With-DRF Specification icon. It may already be highlighted, but select it again,
regardless. The Geometrical Tolerance window appears.

Change the Numerical value to 0.007 and select the Maximum Material Condition
icon .
Select OK , then select Close . The tolerance appears. The lower segment is attached to the
upper segment so that if the upper segment moves, the lower segment moves with it.
Save and close the document.

Open the Position - Rectangular Pattern document again. Ensure that you open the
original document, not the one just saved.
Select the Tolerancing Advisor icon, then select A|B|C in the window and pick the
.3750 dimension.
Select the Position-with-DRF Specification icon. The Geometrical Tolerance
window appears.
Change the Numerical value to 0.02 and select the Maximum Material Condition icon.
This time, you will create a composite tolerance of position.
For the composite tolerance, the upper segment controls the location of the hole pattern in
reference to the datums, and the lower segment controls the spacing and orientation of the
pattern, but not the location of the pattern.
Select the 2 Segment Composite Tolerance option. The other options become available.

Change the Numerical value for the composite to 0.007, then select the A and B options
for Repeated Datum(s) . You can only use datums that you previously used and in the same
order as they were previously used.
