[solved] Problem DXF Export
Hello,
I think I am going crazy .... I just want to export a simple sketch ... I looked for help on google but found nothing ...
(except that I can't export 3d objects to dxf - ohhh REALLY ? (this was sarcasm - sorry) )
I did it like described in the manual - click on the project tree on the sketch - the file - export - dxf - and tried to open it in LibreCAD...
and all I see in libre cad is one line - what do I make wrong ?
attached is the freecad file - the dxf result and a screenshot from libre cad ...
Please help me ...
BTW FreeCAD version is:
OS: Ubuntu 14.04.1 LTS
Word size: 64-bit
Version: 0.14.3702 (Git)
Branch: releases/FreeCAD-0-14

Re: Problem DXF Export
My first guess is a wrong projection direction/plane. As a temporary workaround you could duplicate the sketch. and rotate it to lie in the x-y plane.claus007 wrote:and all I see in libre cad is one line - what do I make wrong ?
EDIT: I was just my first guess, before i realized that you attached a FreeCAD file.
The dxf file looks like Sketch001 viewed from the top. I don't know much, if there is any special handling of sketches. By default, objects are projected to the xy-plane. There is an option to project according to the camera orientation in the 3d view. But this option is disabled by default and AFIAK there are currently problems, when projecting non-solid geometry.

Re: Problem DXF Export
Well first things first, how about you tell us which sketch exactly you were trying to export.
Your TabletSocket01.fcstd file has 3 sketches. How are we supposed to know which one you want to export?

It may also look like Sketch002 viewed from the top.shoogen wrote:The dxf file looks like Sketch001 viewed from the top.
Re: Problem DXF Export
i selected one sketch, went to edit -> duplicate selections. then i reset the placement. (edit -> Placement) and exported the sketches one by one. (see post above)
Re: Problem DXF Export
Another way would be to use Draft Shape2DView on the solids instead.
Re: Problem DXF Export
yes, now it worked - sorry but this is a little bit cumbersome, isn't it ? As long as it is obvious that skectch only have to dimensions....shoogen wrote:i selected one sketch, went to edit -> duplicate selections. then i reset the placement.

But nevertheless thanks for the answers. For the future - Is this mentioned anywhere in the documentation ?
Re: Problem DXF Export
If exporting the first "Sketch" to DXF with the current stable release, the arcs will be reversed. A fix was added to the current development release available through the Daily Builds PPA.
Here's Pad, Pad001 and Staender projected to the XY plane with Draft Shape2DView. Those objects can then be exported as DXF.
As I said, you need the Daily Builds PPA version to export arcs correctly.

Re: Problem DXF Export
By definition a sketch can only be on a plane, hence 2 dimensions.claus007 wrote:As long as it is obvious that skectch only have to dimensions....
Please do not fault FreeCAD for that. The fault goes to Autodesk which chose to export 3D data in a proprietary, undocumented format (ACIS).claus007 wrote:(except that I can't export 3d objects to dxf - ohhh REALLY ? (this was sarcasm - sorry) )
