The next two exercises will demonstrate how to apply a multiple single-segment toleranceand a composite tolerance using the same model.Open the Position - Rectangular Pattern document. Some datums and a dimensionalready exist.Select the Tolerancing Advisor icon.The Semantic Tolerancing Advisor windowappears. Select A|B|C in the window, then select the .3750 dimension.The window expands.Select the Position-with-DRF Specification icon.The Geometrical Tolerancewindow 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 didearlier.Next, you will create a multiple single-segment tolerance of position. The upper segmentcontrols the location of the hole pattern in reference to the datums. The lower segmentcontrols the spacing and orientation of the pattern and the location of the pattern.Select the Tolerancing Advisor icon again.The Semantic Tolerancing Advisorwindow 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.Geometrical Tolerancing, Page 240©Wichita State University
CATIA Functional Tolerancing & AnnotationCATIA® V5R25Change the Numerical value to 0.007 and select the Maximum Material Conditionicon. Select OK, then select Close. The tolerance appears. The lower segment is attached to theupper segment so that if the upper segment moves, the lower segment moves with it.Save and close the document.Geometrical Tolerancing, Page 241© Wichita State University
CATIA Functional Tolerancing & AnnotationCATIA® V5R25Open the Position - Rectangular Pattern document again.Ensure that you open theoriginal 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 Tolerancewindow 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 inreference to the datums, and the lower segment controls the spacing and orientation of thepattern, but not the location of the pattern.Select the 2 Segment Composite Tolerance option. The other options become available.Geometrical Tolerancing, Page 242©Wichita State University
CATIA Functional Tolerancing & AnnotationCATIA® V5R25Change the Numerical value for the composite to 0.007, then select the Aand Boptionsfor Repeated Datum(s). You can only use datums that you previously used and in the sameorder as they were previously used.
