SmartGD&T™ Training Models—Geo-Fact II™
 
Geo-Fact I
An "imperfect geometry" artifact for demonstrating simple and composite Section and Surface Profile tolerancing, Dimension Origin versus Size tolerancing, Unconstrained and Orientation Constrained Actual Mating Envelopes, and the problems associated with short arcs. As in Geo-Fact I, an integral tooling ball is the only "perfect geometry" feature serving as a reliable metrology reference. 

Materials: Polyurethane, Steel
