Automatic DXF Import

Prepared DXF Files
The DXF Translator software allows the control to load and translate a DXF style
drawing created in Autocad
®
or Autocad LT
®
into an EIA part program. Certain
guidelines must be observed when creating the CAD drawing to allow the control to load
and understand the file. The optional DXF translation utility is enabled through a
password provided by your control supplier.
Drawing Format
There should be nothing on the cut layer except lines, arcs, circles and text commands.
Do not put dimensions or notes on the same layer as cut data.
Elliptical segments, squares and polylines are not supported. Divide these elements into
short arcs or line segments. You can use the ACAD EXPLODE command to convert
POLYLINES into segments.
The end angles of two arcs from any intersection point cannot be within the same
quadrant.
Text commands determine cut sequence, and determine the path through multi-segment
intersections. Text commands are placed on the drawing with the text feature of your
CAD program. The size of the text is not important. However, the location of the text is
extremely important. Text must be left justified and text commands must be “snapped to
the appropriate intersection or pierce points.
Text commands indicate pierce points and cut direction. Note that the directional
commands should only be used to determine the direction of the next line segment when
more than one exit path exists at an intersection of segments.
Text Commands
1
Indicates the first pierce point (subsequent pierce points follow in numerical order)
+ Indicates a Counter-Clockwise circle
- Indicates a Clockwise circle
Directional Commands
The following commands indicate the next segment’s direction, if it is a line, or the
ending angle, if it is an arc, if the angle is:
R 350
° to 10°
RU 0
° to 45°
UR 45
° to 90°
U 80
° to 100°
UL 90
° to 135°
LU 135
° to 180°
L 170
° to 190°
LD 180
° to 225°
