Summary	0002736: Exported DXF shows only sheet format but no object
Description	After exporting a dxf or svg file. The sheet format of the 2D drawing is visible in programs like USBCNC QCAD, autocad etc, but the actual drawing object can not be made visible by the software. This, while the drawing is visible in FreeCad itself after importing the dxf in to Freecad. I have the same trouble with exporting to svg. The only difference is the report window gives the message "The export list contains no shape"
Steps To Reproduce	- Create a flat 2D drawing from a 3D part in the Drawing workbench. - Select Page in the Model tree on the left side. Also tried select page and al the items in the page branch, with the same result. -File -> Export -> Autodesk DXF -> save - Open the file in on of the above mentioned programs.
Tags	No tags attached.

The issue seems to be related to the "Export Drawing Views as blocks" option in the Import-Export / DXF preferences. If the checkbox is unchecked, the views are displayed in the DXF, but they are stacked one over the other and their orientation is wrong. The problem affects DraftSight as well.

yorik 2016-10-19 17:02 administrator ~0007397	Is it possible to attach a freecad files that presents the problem? Also, there are serious problems with exporting DXF files from Drawing pages when the corresponding DXF template version is higher than R12.

yorik 2016-10-19 22:52 administrator ~0007405	Ok the problem is in the template indeed. Try changing the template property (which links to an svg file) to something not existing (just remove the .svg for ex.). The page will be marked with a red ! sign. When exporting the page to dxf, since a valid template cannot be found, the file will be exported with a default, empty template. This will work. I said that a hundred times, but the people who did these default templates unfortunately didn't want to hear... I suggest you re-save the templates you will use often as R12. There is still also a problem with ellipses and splines. Since with the trick above we are exporting a dxf R12 file, which didn't have ellipses nor splines at that time, some apps like DraftSight will open the file but refuse to display any non-R12 entity. LibreCAD and QCAD don't have that problem of conscience :) So the solution is either to open the file and re-save from libreCAD or QCAD, or set preferences->Import/export->DXF->treat as polylines. But your curves will be faceted.

yorik 2017-01-27 16:11 administrator ~0008029	yes i think this can be closed
