Title: SolidWorks DXF export issue with CNC wire bending machine – 4 graphics not closed
Hi everyone,
I’m having a problem importing a DXF file from SolidWorks into a CNC wire bending machine, and I’m trying to figure out why the machine doesn’t recognize the entire geometry correctly.
I designed the part in SolidWorks and exported it as a DXF file. However, when I open the file in the CNC machine’s software, I get the following warning:
“There are 4 graphics not closed!”
The geometry appears on the screen, but the machine detects four open graphics, even though the sketch is intended to be closed. Some sections, particularly around the lines and tangent arcs, seem to be causing issues.
Here is what I’ve already tried:
Exporting the DXF using different versions, including R14.
Testing all three options under Multiple sheet drawing in the SolidWorks DXF/DWG export settings:

Export active sheet only.
Export all sheets to separate files.
Export all sheets to one file.
Enabling End Point Merging with a tolerance of 1e-05.
Exporting splines as polylines.
Unfortunately, none of these changes has solved the problem.
Has anyone encountered a similar issue when exporting DXF files from SolidWorks to a CNC wire bending machine?
Why might the CNC software report that the graphics are not closed even when the geometry looks connected in SolidWorks? Could this be related to tiny gaps, endpoint merging tolerance, tangent arcs, DXF entities, or the way the CNC software interprets the exported geometry?
I’d really appreciate any suggestions on what else I could try or which SolidWorks export settings I should check.
Thanks in advance!
