Application
A new function allows you to open standardized 3-D CAD data formats
directly on the TNC. It is irrelevant whether the file is available on the
hard disk of the iTNC or a connected drive.
The file can simply be selected via the file manager of the TNC, just
like NC programs or other files. This permits you to check quickly and
simply for problems directly in the 3-D model.
The TNC currently supports the following types of file formats:
 STEP files (file extension STP)
 IGES files (file extension IGS or IGES)
