problems with OpenSCAD

[jmaustpc]

OS: Windows
Word size of OS: 64-bit
Word size of FreeCAD: 32-bit
Version: 0.16.6704 (Git)

There is a newer FreeCAD 0.16.7706 with some bug fix back ports for Win64,

Thanks for your help!

Okay I have done some more debugging

The CSG circle commands cause dxf files to be created.
Hull causes openscad to be executed with hull(){import(file = "fc-05088-493039-000001.dxf"); import(file = "fc-05088-493039-000002.dxf");} where the the two dxf files are as per the circle statements.
Then there is an attempt at importing the dxf file that openscad creates.

The problem occurs in OpenSCAD2Dgeom.py in function importDXFface at the statement
layers = importDXF.processdxf(doc,filename) or importDXF.layers

The importDXF.processdxf does not complete but causes the execute function of the class CGALFeature to be re- executed.
Note: CGALFeature is in the python execution stack. So things just loop creating dxf files and calling openscad to perform a hull request.

So I conclude that the problem is in the dxf library. I am not sure if Yorik maintains the library any more.
I will send him a pm.

Don't think I can progress any more.

could you guys isolate/attach here the dxf file that causes problems?

I started with 0.16; it was much worse, at least for this particular (OpenSCAD) issue

[yorik]

Thanks Keith! Will have a look...

[jon_bondy]

I wonder if the DXF files are being created, but in a location that OpenSCAD cannot find (or does not use by default) on my system.

Jon,

In one other case on Windows, I found that the DXF libraries would stop being downloaded again and again only if the Macro path was set to C:/Users/jon/AppData/Roaming/FreeCAD rather than C:/Users/jon/AppData/Roaming/FreeCAD/Macro.

Maybe you could try that.

Okay I found where the looping is occurring. Its happening because of a doc,recompute at line 1490 in ImportDXF.py which is in /usr/lib/freecad/Mod/Draft.

I am not sure why it is causing a problem and am in discussion with yorik who is the module owner.

Anyway if I comment out the recompute I can load the CSG file
