Rectangular Bolt Pattern datum

[sally]

4.2 B&S no cad
my issue is the true position of a bore at MMC called out to -C-, the plane and
-D-, the rectangular (4) bolt pattern at MMC.

All the individual features are programmed just don't know how to get a MMC from the bolt pattern.

Thanks in advance for any suggestions

I used to a perfectionist but gave it up because I wasn't any good at it.

Go to Insert/Dimensions and turn off the Use Legacy Dimensions. Then Insert/Dimension/True Position will open the XactMeasure GD&T. It allows you to pick the bolt pattern and properly evaluate to the FCF.

If your bolt pattern is a Datum then you need to create a Feature set out of the bolt holes first.

Then Define your Datum feature to the Feature Set

Be sure to type in the nominals for each feature since you have no cad.
