7.1 Processing DXF files (software

option)

Application

DXF files created in a CAD system can be opened directly by the TNC,

in order to extract contours or machining positions, and save them as

conversational programs or as point files. Plain-language programs

acquired in this manner can also be run by older TNC controls, since

these contour programs contain only L and CC/C blocks.
If you process DXF files in the Programming and Editing operating

mode, the TNC generates contour programs with the file extension .H

and point files with the extension .PNT by default. If you process DXF

files in the smarT.NC operating mode, the TNC generates contour

programs with the file extension .HC and point files with the extension
.HP

by default. However, you can choose the desired file type in the

saving dialog. Furthermore, you can also save the selected contour or

the selected machining positions to the clipboard of the TNC and then

insert them directly in an NC program.

The DXF file to be processed must be stored on the hard

disk of your TNC.
Before loading the file to the TNC, ensure that the name

of the DXF file does not contain any blank spaces or illegal

special characters.(see "File names" on page 122)
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 TNC does not support binary DXF format. When

generating the DXF file from a CAD or drawing program,

make sure that you save the file in ASCII format.
The following DXF elements are selectable as contours:

LINE (straight line)

CIRCLE (complete circle)

ARC (circular arc)

POLYLINE
