File specified in ModelPath property can have either of the above extensions.

Import/export operations can be performed programmatically. See IModelEx for details. The format in which the model is persisted is identified by the file extension. Additional save/load options can be supplied via IModelEx with the help of  IDataContext and ISTLDataContext. For STL file format DG Kernel offers a way to store structured models in a file folder, called STL Directory Tree. See STL Tree for details

All objects of STL format and most of the objects in VRML format are imported as Mesh Sections. Standard VRML objects like Box, Sphere and Cone are imported as parametric (Generic 3D Object or Surface Of Revolution) objects.

Version information about a format (mostly related to AutoCAD formats) can be accessed via interfaces described at Data Exchange API
