True Position- Newbie question

[1CMM4ME]

Drawing Indicates a group of holes true position to datums A-B-C within .008 , regardless of feature size. Where do I put this information, so the machine knows this? Thanks to all for the help.

You set up your ABC datums for your alignment. You then measure the diameters & TP dimension them.HTH

[Paul Sarrach]

Your alignment is to ABC, correct? After you align take the holes the tolorence them.

Your BASIC DIMS should be your X,Y,Z theoritical. In your auto features just enter these from in the XYZ boxes. Just remember to set your origin correctly. Then dimension accordingly with the correct axis.

You assign the 0.008 TP in the True Position Window. Near the top of the window it will say Tolerances and there will be a drop down box. Open the drop down box and find TP and select it. Enter 0.008 in the Value Boxes.

Once you have selected the feature you want to tolerance from the feature list click create to add the tolerance command to your program.

Measure A, align to it and define it as datum -A- (Insert/Dimension/Datum Definition)
Measure B, align to it and define it as datum -B-
Measure C, align to it and define it as datum -C-

Make sure that Insert/Dimension/Use Legacy Dimensions is NOT Checked!!!!

Then proceed to insert the call using Insert/Dimension/True Position.

It will give you a lot of info about where the hole is with repect to the datum structure.
