I am beginning to attempt to program off a cad model. I have a sample part, every time I press cad=part my alignment moves off my cad model. I am actually trying to program off of cad on a part I have a sample for before I make a program off a part that I have no sample for.
How many times have we seen people ask for help, and when they post the code that SO MANY people want to see, and one of the FIRST things they always say is "Why don't your THEO and VECTOR match your alignment?" Why? Because they did a 'standard' alignment WITHOUT using CAD=PART!
basic plane-line-line alignment WITH the 'datum corner' at X0Y0Z0 without using CAD=PART. As you can see, all the THEO & Vectors are to MACHINE CO-ORDINATES

As you can see, ALL the THEO & VECTORS are now to "PART ALIGNMENT", they are no longer to MACHINE CO-ORDINATE. The ACTLs are still to MACHINE CO-ORDINATES, because that is what they were measured to, but the THEO & VECTORS are now exactly to PART ALIGNMENT.
Now, isn't that a pretty handy function when used correctly? Just like any other tool, if not used correctly, it won't work correctly.
