(1)For type 190, 0 means unparameterized surface and 1 parameterized. The
plane surface type is unbounded unless it is subordinate to another entity,
such as the Bounded Surface Entity (type 143) or the Trimmed parametric
Surface Entity (type 144), that references its bounding geometry.
IGES levels
The system adds all supported geometric IGES entities that are associated with
IGES level <n> to an Alias layer called LEVEL<n>.
For example, if a 126 B-spline entity directory entry indicates that it is on level
42, then it is added as Layer LEVEL42.
JT
The JT Open Program develops and supports the DirectModel format JT for
the visualization of 3D models.
Autodesk DirectConnect supports the import of JT (up to V10) files into the
Autodesk Alias, Autodesk Maya, Autodesk Showcase, Autodesk Opticore Studio,
3ds Max/3ds Max Design and VRED software. See installation information in
Install Autodesk DirectConnect. (page 7)
