Contour by Face and Contour by Edges fails

[herbk]

Hi Memfis,

for only creating a milling path you may be right.

But usualy we make the whole construction with FC, including Fem simulations and output for presentations.

If you turn on debug and trackModule for PathUtils

could you explain how to do that? There are some handy output tools like Base:Console().Message which are accessible in /Mod/Path/App but do not work in /Mod/Path/libarea.

There seem to be some switches which can be set run-time via python but does this require full rebuild? ( 3h here ).

Evening Freman,

If you turn on debug and trackModule for PathUtils

could you explain how to do that? There are some handy output tools like Base:Console().Message which are accessible in /Mod/Path/App but do not work in /Mod/Path/libarea.

There seem to be some switches which can be set run-time via python but does this require full rebuild? ( 3h here ).

Open the PathWB module of your choice in the PathScripts directory.
Look for a line similar to the one below - usually one or two lines after the initial import modules section at the beginning/top of the file.

Code: Select all

PathLog.setLevel(PathLog.Level.INFO, PathLog.thisModule())

Change the capital INFO to DEBUG (all caps).
Reload the module or restart FreeCAD.

If your computer starts lighting up, buzzing, and shaking, step away from the terminal, lest you be sucked down a worm hole to another PathWB dimension.

… Or, you can just close the lid on your laptop. You know, whatever works.

Cheers mate,
Russ

If you open the parameter editor (Menu->Tools->Parameters) the very first folder is "LogLevels". It has a parameter "Path.Area". Can this be used to get debug output out of libarea calls?

[freman]

thanks to both of you for the replies. Swapping WB is a nice trick, I'd been wasting time closing FC and restarting.

That covers the question as posed in relation to the python code here, I have a similar problem getting output from some parts of the c++ code but I'll start a separate thread about that to avoid distracting this one.

It is most likely an OCC bug in the discretization method I choose for B-spline, with OCC class GCPnts_QuasiUniformDeflection. Change it to GCPnts_UniformDeflection works. There are other discretization methods available. You can check the Python doc string of TopoShapeWire.discretize() for more info. If it is necessary in the future, I can expose these methods as additional parameter in Path.Area.

This PR went in, but now I cannot compile:

Code: Select all

2>D:\FreeCADGit\src\Mod\Path\App\Area.cpp(367): error C2065: 'GCPnts_UniformDeflection': undeclared identifier

To fix this, I must add the line

Code: Select all

# include <GCPnts_UniformDeflection.hxx>

outside the #ifndef _PreComp_ block.

Interesting, I built it and didn't have that problem. Is this Windows build specific?

Is this Windows build specific?

I don't know since I only have Windows and MSVC 2017 and I compile according to Compile on Windows.

Fixed here. There is a missing header in Windows precompiled header.
