Exporting a tool path in 3D .dwg from plan view, parallel projection, lines only, outputs with some of the curves in reversed orientation. I remember this was solved at one point in the past but I can’t find the link right now. I believe it ended up having something to do with curves being left t…

Lots of good info here…are you using SU 2019 for the export? [image] Polylines with real arcs for CNC Router? Pro Hello, my problem is as follows. I would like to send 2D shapes that have arcs for rounded corners to a CNC router for cutting. For simplicity imagine im usin…

Yes, that was the conversation I was looking for, thanks. @IanT for the win! Got to dig deeper into this, I’m using 18 for now, I’ll update when I can spare the time. Is there documentation of the 19 build being better? [image] Polylines with real arcs for CNC Router? Pro …

I installed SU 2019 and did some testing & still see some oddities, but it se ems to be better. Re-created your parts to illustrate at least one odd behavior.(holes move off part when flipped copies are present) this occurs in my CAD software but not in SheetCam. see images & file below Note: I ex…

I don’t see any errors in DWG TrueView 2019. Exported to DXF from SU 2019 in AutoCad 14 and AutoCad 2018 formats. Sounds like bugs at the receiving application end. [image]

@Anssi , in all cases I have seen, the issue doesn’t occur at all in cad viewer/softwares. The export looks fine when you open it up there. The problem arises when you put that “seemingly fine” file into CAM. The issue then pops up with the Arcs flipping…

I uploaded the .dxf (V2007) generated by SU 2019 (see above)

I see you got a pretty good result there. Unfortunately I tried SU 19 last week with a newer CAM software for a brand new 5 axis machine we have. I got the same Arc flipping issue as before in my tests. (DXF in that case). Gkernan’s extension produces good results for me at least consistently. I am…

[image] IanT: The problem arises when you put that “seemingly fine” file into CAM. The issue then pops up with the Arcs flipping… I tried a simpler file with only an arc and its mirror image and looked through the DXF. Nothing abnormal there (predictably, flipped entities get a negative extru…

“I see you got a pretty good result there.” For this particular file I did, but that is not always the case…and to be fair I need to give SU 2019 more time to see if this is resolved or even if it is on SU side of things.

.dwg export curves are reversed

No documentation(that I am aware of)…just comments that 2019 exporting to dwg has been improved.
