Data Model
The JT data model is capable of representing a wide range of engineering data. This data can be very lightweight, holding little more than facet data or it can be quite rich, containing complete NURBS geometry representations along with product structure, attributes, meta data and PMI. It also supports multiple tessellations and level-of-detail (LOD) generation.
- Product Structure - assembly, part, instance
- Facet - polygon, polygon set
- Lighting - light set, point light, infinite light
- Textures
- Precise Geometry and Topology - point, curve, surface, face, loop, edge, vertex
- Boundary representation (B-rep) could used either JT B-rep or XT B-rep(Parasolid) format.
- Geometry Primitives - box, cylinder, pyramid, sphere
- Product Manufacturing Information (PMI) - GD&T, 3D annotations
- Attributes / Properties - text, integer, float, date, layers
- Meta data - property filters, transforms, bounding box definitions

Famous quotes containing the words data and/or model:
“This city is neither a jungle nor the moon.... In long shot: a cosmic smudge, a conglomerate of bleeding energies. Close up, it is a fairly legible printed circuit, a transistorized labyrinth of beastly tracks, a data bank for asthmatic voice-prints.”
—Susan Sontag (b. 1933)
“It has to be acknowledged that in capitalist society, with its herds of hippies, originality has become a sort of fringe benefit, a mere convention, accepted obsolescence, the Beatnik model being turned in for the Hippie model, as though strangely obedient to capitalist laws of marketing.”
—Mary McCarthy (1912–1989)
