|0001769||FreeCAD||Bug||public||2014-09-30 14:07||2014-12-04 13:40|
|Target Version||Fixed in Version||0.15|
|Summary||0001769: Models don't load as solids in Sprutcam|
|Description||When I create a model and save it as freecad or iges the units seem to get mixed up. The faces of a cube will be the correct size but the location will be wrong when loaded into SprutCam. The outlying faces are 10 inches from the origin but are only 10mm in size. It appears the units have been mixed or assumptions about the units have been made. Sprutcam loads freecad files directly but both freecad and freecad made iges files display this issue. Other cad softwares don't show this issue in Sprutcam.|
|Steps To Reproduce||Create the default 10mm cube and save as iges.|
Load into Sprutcam and enjoy an exploded view. (See included screen shot.)
Exporting the Cube in IGES format, then opening that IGES file in FreeCAD produces SelfInteresct errors with every edge and vertex of the cube, and object is not a solid or shell, just a compound of self intersecting edges and vertexes of faces.
I see SprutCAD uses STEP format as well. I would recommend using that format until IGES is working properly.
This is with both FreeCAD 0.14 Release (3705) and -
OS: Kubuntu 14.04.1 LTS
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.15.4097 (Git)
Python version: 2.7.6
Qt version: 4.8.6
Coin version: 4.0.0a
OCC version: 6.7.1 (OCE 0.17 dev)
||The STEP format produces the same error in SprutCam.|
I don't have this problem.
Since you said it also happens with STEP format I tried a different CAD application,
VariCAD Viewer and there everything looks fine there. Also when loading the same cube into FreeCAD the geometry checker doesn't report any problems.
So, either it's a problem with the OCC/OCE version or SprutCAM is wrong, i.e. that it maybe doesn't support a certain format of IGES or STEP.
My OCC version: 6.6.0 under Windows
TJ might want to try entering -
into the python console before export to IGES.

Strangely that did fix the problem. I'm not sure what that does but it did work for this. The problem still occurs with the FCStd files though.
How can this be made a standard command when exporting iges.
The next post below the FreeCAD forum post that is referenced above, I asked if this should be made an option in the Export function and I do not know of any further thoughts on this. This could be wrapped easy enough in a Macro with toolbar shortcut, which would work well until a more permanent solution comes.
We would want this to be an option, as this does not seem to work when used on 2D Draft elements, as the now default method does. Perhaps wmayer may want to close this now and we can open a feature request for the option. Export for IGES 2D and IGES 3D Solid.
The Part settings page has been split into three pages now. Two of them does the handling of IGES and STEP export. On the IGES settings page there is a check box "Enable B-REP mode" which you have to activate.
And also for every program start this settings is used to enable or disable the iges.brep.mode.
