6.8 Generating Contour Programs
from DXF Data (Software
Option)
Function
DXF files created in a CAD system can be opened directly by the TNC,
in order to extract contours and save them as plain-language
programs. Plain-language programs acquired in this manner can also
be run by older TNC controls, since these contour programs only
contain L, CC and CP blocks.
If you process DXF files in the Programming and Editing operating
mode, the TNC generates contour programs with the .H file extension.
If you process DXF files in the smarT.NC operating mode, the TNC
generates contour programs with the .HC file extension.
Opening a DXF file
8 Select the Programming and Editing operating mode
8 Call the file manager
8 In order to see the soft-key menu for selecting the file

8 Select the desired DXF file, and load it with the ENT
key. The TNC starts the DXF converter and shows the
contents of the DXF file on the screen. The TNC
shows the layers in the left window, and the drawing
in the right.
The DXF files to be processed must be stored on the hard
disk of your TNC.
The DXF file to be opened must contain at least one layer.
The TNC supports the most common DXF format, R12
(equivalent to AC1009).
The following DXF elements are selectable as contours:
„ LINE (straight line)
„ CIRCLE (complete circle)
