Perhaps dumb newbie question....

Hello fellow Forum users

I have been thrown in the deep end, and find myself struggling to tread water. So any help would go a very long way.

My company has a Romer Infinite 2.0 arm and a very nice Granite table. They want to hand me a part and have me load a cad model into polyworks, then "scan" the part and do a comparison between the part and the CAD model. This all sounds quite simple on the surface except that I am having trouble defining for the program where the Granite table is in relation to the arm, the finished part, and the cad model. If someone could point me in the right direction it would be greatly appreciated.

The relationship of the arm, table, and part to one another has zero importance.

Once the part is scanned, datum features are created & extracted from the scan data. Those features are then correlated to the same nominal features on the cad model and an alignment is performed.

That is the best workflow, in a (very simplified) nutshell.

In your situation, and depending on the part, I'd recommend a best-fit alignment for simplicity's sake.
