I have been getting extremely frustrated with OpenBuilds CAM Gcode Creator when importing DXF files. When using LibreCad, Circle objects in DXF files (all DXF export versions) do not show. They are listed in "Documents", but do not show up in the view, and attempts to generate toolpaths fail. Non-circle objects show up just fine. When using QCad to export DXF (only version available is R15), Circle objects are not closed, resulting in "pacman" toolpaths. I have to explode all the circles before saving. Annoying, and it makes the file more difficult to modify later.
First of all, you have to convert everything to Polylines, and then export as DXF R14/R15 No splines, arcs, circles, etc - convert it all to Polylines See docs:software:file-errors [OpenBuilds Documentation] My go-to for fixing DXFs is QCAD - see here for a similar example and I also gave that user a walkthrough: See Post #18 in Problems with importing DXF into OBcam
Yeah, QCAD mostly works. Except Arcs. They won't convert to Polylines (unless you buy pro?), and OpenBuilds CAM randomly reverses the arc direction.
I checked in QCAD v3.27.6.0 (latest version, released 17 May 2022) and its still there -- make sure yours is up to date. It's really quite simple in concept and execution 1) OpenBuildsCAM needs Polylines 2) So its a simple select-all and convert it to polylines - then save If you don't mind keyboard shortcuts - in QCAD that would be Open the file > [Ctrl+A] > [O] > [C] > [Ctrl+S] and its done Quite easy and shouldn't take you more than a few seconds Other CAMs other than OpenBuilds CAM also prefer Polylines (as its a closed vector type) so its good to know how to do
Does not work [Ctrl-A] Selects All [O] Does Nothing [C] Does Nothing [Ctrl+S] Saves File Arc is still an arc. Two different computers, same results. Debian, manual install, 3.27.6 Fedora, RPM install, 3.27.2 Are you sure this is not a "pro" function? Your screenshot shows you are working with a pro trial version.
Try the Windows version, perhaps the Linux versions are just too different The windows installer version just "works" - didn't know you were on Linux (Do mention nonstandard workflows earlier on please - otherwise we will of course assume a more standard Windows environment). There are very few good CAD/CAM options on Linux - while the idea is noble, you may soon find Windows being an advantage in this kind of world. Even if its a pro function, since the trial never expires - just limits runtime to 15 mins - and it takes seconds to do so you are in and out before that limit hits - its still a perfectly acceptable workflow Or spend the 36euro - it's a bargain too
