6.10 Importing of DXF Contours
Fundamentals for DXF import
Contours that exist in DXF format can be imported into TURN PLUS.
DXF contours describe
„ Workpiece blanks
„ Finished parts
„ Contour trains
„ Milling contours
For workpiece blank and finished-part contours as well as for contour
trains, DXF layers should contain only one contour. Milling contours
can contain and import multiple contours.
Requirements of a DXF contour or DXF file:
„ Only two-dimensional elements
„ The contour must be in a separate layer (without dimension lines,
without wraparound edges, etc.)
„ Turning contours (workpiece blanks or finished parts) should be
shown above the turning center (if this is not the case, then they
must be revised in TURN PLUS)
„ No complete circles, no splines, no DXF blocks (macros), etc.
„ The imported contours may consist of no more than 4000 elements
(lines, arcs). In addition, up to 10 000 polyline points are permitted.
„ The file name can have up to 20 characters
Contour preparation: Since the DXF format is fundamentally
different from the TURN PLUS format, the contour is converted from
DXF to TURN PLUS format during the import. The following changes/
additions are made during this process:
„ Gaps between contour elements are closed
„ Polylines are transformed into linear elements
„ The starting point of the contour is defined
„ The direction of rotation of the contour is defined
Sequence of a DXF importation:
U Selection of the DXF file
U Selection of the layer, which contains only the contour(s)
U Import of the contour(s)
U Saving (and editing) of the contour in TURN PLUS
