    3 The files in this directory are conversions of the NIST MBE PMI test models
    4 into the AP203 file format.  These conversions are also in the public domain.
    5 
    6 Originals are from http://www.nist.gov/el/msid/infotest/mbe-pmi-validation.cfm
    7 
    8 Models 7 through 10 have been assembled into a single file, guided by the example
    9 PDF provided with the original NIST data set.

   13 NIST has created a Test System to measure conformance of Computer-Aided Design
   14 (CAD) to American Society of Mechanical Engineers (ASME) standards for Product
   15 and Manufacturing Information (PMI), specifically geometric dimensioning and
   16 tolerancing (GD&T) information.
   17 
   18 As part of this Test System, CAD Models were prepared.
