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:
“To write it, it took three months; to conceive it three minutes; to collect the data in it—all my life.”
—F. Scott Fitzgerald (1896–1940)
“If the man who paints only the tree, or flower, or other surface he sees before him were an artist, the king of artists would be the photographer. It is for the artist to do something beyond this: in portrait painting to put on canvas something more than the face the model wears for that one day; to paint the man, in short, as well as his features.”
—James Mcneill Whistler (1834–1903)
