The TNC also transfers two workpiece-blank definitions
(BLK FORM) to the contour program. The first definition
contains the dimensions of the entire DFX file. The
second one, which is the active one, contains only the
selected contour elements, so that an optimized size of
the workpiece blank results.
The TNC only saves elements that have actually been
selected (blue elements), which means that they have
been given a check mark in the left window.
If you call the DXF converter from a form, smarT.NC
automatically closes the DXF converter after you have
completed the SAVE SELECTED ELEMENTS function.
Then smarT.NC writes the defined contour name to the
input field from which you have started the DXF
converter.
