Re: Contradicting dimensions?
When you do Ordinal dimensions (back to a single edge in X and Y) you are implying a different set of tolerances than the typical dimensioning you will get from FIRST drawings. I do wish they would give us higher resolution PDFs, or even better DWG/DXF or solid files. I wonder how many people simultaneously recreated the fields in various cad packages this year.
Also note that PTC was planning on releasing Pro/E models of the field, so you can always take measurements from that.
If you want to know way too much about dimensions, pick up a copy of ANSI/ASME Y14.5-2009 (I have a copy of the 1978 version that I got for a buck).
