Measuring CAD model

[Underspec]

Haven't used CAD much. Need help measuring CAD model. Do I need to create alignments first? Also, my probe seems to be in the wrong vector when measuring features.

I do my iterative alignments to non-datum features just to locate the part to the machine. Then I do a regular alignment to my print datums.

1. no you dont have to do alignments if all you are doing is measuring a few features on the cad model. If you are programming off the cad model for a future run...yes.

2. the probe orientation to the cad model probably isnt correct because the coordinate system of the cad model isnt oriented the way you want it. For this you have a few options, 1. have the cad department orient the model the way you want it, 2 use the machine-cad setup (F5). and if you are running 4.0 or higher, you can change the coordinate system the way you want it.

I usually do the same thing or an iterative to the print datums and then a regular to them.

Ok looks like I have to use alignments per print to find basic dimensions I want. My probe vector was wrong cuz I did not rotate my angles to match x,y,z like I would in real measuring.

Just Align the part like it is on your machine offline style.
execute the short stuff up to the alignment
go DCC and program away. No need for CAD = PART.
