So I actually tried that method as well. Took the P&P info that was provided to us in Mils, put together an excel formula sheet which converted all X,Y to mm which the aoi uses. Then came to the horrible conclusion that there was something in the cad way off to the bottom left of the job which was throwing off any chance of getting a solid 0,0 at the corner of the board.Checked the methodology of the machine as well, everything was as it should be.
I really lucked out however. I put a service request in to Mentor Graphics to see if there was any way to change insert coords on a mass basis instead of single part one-by-one. If anyone needs to know the answer is no, it is not possible to do this in camcad professional. You would literally need to step through every placement and change the origin to center and snap to it, then save it all...etc,etc.
However, the service engineer did ask what I needed this for and after advicing him of my issue gave me the answer I had been looking for. There's an output file that has the option to change aoi export creation from part origin data, to part centroid data. All I had to do was locate the file comment out the origin data option and bring in the centroid option.
So happy the service engineer asked that extra question. Saved me a ton of hassle, and made for some very pleased customers.
If you use camcad professional the file is called "Agilent_AOI.OUT" Here's a cut out from the response I received, hope this can help others as well
;*/-------------------------------------------------/* ; Source of positions ; Select whether the XY position of the part is ; based on the centroid location or the CAD data ; Default is CENTROID .COMP_POSITION ORIGIN ;.COMP_POSITION CENTROID ;*/-------------------------------------------------/*
Change the lines so that the CENTROID line begins with a "." and the ORIGIN line begins with a ";" ("." Is active command line and ";" is comment line)
