Hello I tried to open this file in CAM Openbuilds and I got the following issues: - the arc are not present (!) - units: my drawing units is centimeter but looking at the result it seems it considers it as mm, can it be changed somewhere? thanks
Export as DXF R14 Polyline format. Yours is in DXF R2007 - line 10 of the file if you view it as Text (notepad) shows AC1021 AC1027 -- AutoCAD 2013- AC1024 -- AutoCAD 2010-2012 AC1021 -- AutoCAD 2007-2009 AC1018 -- AutoCAD 2004-2006 AC1015 -- AutoCAD 2000-2003 AC1014 -- AutoCAD Release 14 AC1012 -- AutoCAD Release 13 AC1009 -- AutoCAD Releases 11 and 12 AC1006 -- AutoCAD Release 10
ah ok, will check it. I used freecad and used normal export. The file is working ok in Fusion 360 and CAMBAM
Fusion is owned by Autodesk, so they have access to the original DXF APIs - so they can support all versions. We can only support DXF R14 reliably as thats the widely used spec in the Open Source DXF parser libraries. The DXF format is proprietary, not open, so the open source parsers were built by reverse engineering the data, and what limited documentation Autodesk released. The older the format, the better its understood We've extended it by adding some extra entities OpenBuilds/OpenBuilds-CAM - but best to still give it DXF R14 polylines. If you have Fusion, you'd not need OpenBuilds CAM anyway, use the built in CAM (superior to the beginner friendly, free, OpenBuilds CAM)
