Mounting part on setup tooling

mcultice
2011 MR1, Romer 7525

I have been programming offline, using only the part model "floating in space", and creating a local coordinate system on the part. I want to bring models of knee blocks, 1-2-3 blocks, and other setup equipment in so I can program around real-world setups, allowing me to simulate datums, etc. I am finding the instructions in the Help screen very vague.

Can anybody give me (or point me to) a step-by-step tutorial on resting a part on a knee block in my Graphics Display Window?

  • Some of the parts we produce are long or thin and fairly flexible; they frequently need to be secured to a block or table to restrain them. This usually makes the primary datum inaccessible.

    To achieve the same end, can I program using the actual model surface, then pick up the mating surface when the part is measured? What modifications have to be made in the alignment to do this?


    If I read your post correctly, the necessary modification requires getting the design engineer to move the datum from the surface you make inaccessible with your fixture/setup to the surface you claim is the "mating surface".

    If the GD&T on the drawing was originally done correctly, it reflects the necessary form, fit, and function requirements of the part and must be adhered to if you wish to remain compliant to the standard.

    There is no magic alignment modification that allows you to just pick whatever feature is most convenient to be the datum.
