I have just upgraded to version 3.37 from 3.5 hoping that the error would be sorted.

When I am cutting a DXF file created by exporting a design in 2D design i keep getting input parse error - radius


any ideas how this may be solved thanks

Do you mean you are on VR Milling version 5.37 ?

Invalid radius and input parse error has cropped up a few times in the past, and has been fixed in VRMilling 5 when issues have been seen.
It's usually to do with an arc being too large or small a radius, or the given endpoint is impossible to reach given the other arc properties.
Some CAM software has also been the cause of errors by creating invalid arcs.

Attach a .dxf file which demonstrates the issue and we'll test it here - you may need to zip it up to let the Forum accept it.

We are using VR Milling version 5.37

I will also look at the 2D file to check there are no strange lines hiding


DXF file added thanks

Thanks for the file.
We can reproduce it here. The issue is to do with the way the CAM wizard tries to recognise arcs and is converting the large curves (shown in attached image) into invalid arcs.
v5.39beta milling has fixed the problem, although you still get an arc which is not true to the original curve, so the option to turn off polyline to arc conversion has been added in the final window of dxf import (see screenshots)

I've also attached the 5.39 Beta file if you want to try it for yourself (please backup the 5.28 VRMilling5.exe file first)
