Re: FreeCad delete nodes

The DXF-format is used as file format by these 2D-CAD-programs: https://librecad.org/ and https://www.qcad.org/en/.
So I would try the above programs first.

Re: FreeCAD on the web

But how many paper authors follow such a standard? All I wanted to say, there exist citing styles, which allow to cite software directly without the need of a corresponding paper. So we can go forward and request proper citation on the FreeCAD website, in order to avoid only mentioned in the text a...

Re: FEM: Status of old GMSH interface PR and discussion of STL meshing through GMSH

I only found http://gmsh.info/doc/texinfo/gmsh.html# ... ource-code but this is not really satisfying. ENABLE_OPENMP should include multithreading. See here: https://de.wikipedia.org/wiki/OpenMP There is also ENABLE_MPI, but it is not used for meshing, according to the above cited Gmsh documentatio...

Re: FreeCAD on the web

we can publish in an open source journal and then we can cite. Actually the world is more electronically and does not need a paper for a citation. The rules for technical citations are defined in ISO 690. The section 5.1 describes how to cite computer programs. See here: http://paedpsych.jk.uni-lin...

I'm working in a macro to generate lattice structures
I would not try to generate a sketch in a makro, but generate the profile directly with Part lines and arcs and make a Part wire from it. As you can calculate all vertexes in the macro, you do not need the sketcher solver at all.

Re: Is there such workbench for charting?

The shown charting example of the OP is not that much related to FreeCAD. But the charting program Visio has in its professional version a 2D-drawing program for mechanics and is used for indoor room planning as well. Furthermore it has a module for piping and instrumentation diagrams usable for che...

Re: FCStd1 Datei lässt sich nicht öffnen

Am besten die FCStd1-Datei kopieren und unter einem neuen Namen mit der Endung FCStd speichern. Dann versuchen diese Datei mit FreeCAD zu öffnen.

Re: Python connecting primitive shapes into one?

You have to append all your ruled surfaces into a list. Then make a Shell out of these Surfaces. myShell = Part.Shell(mySurfacelist) This works only, when all surfaces are properly connected to the next one. You can also create a solid out of the shell. But this requires, that the shell is closed. S...

Re: Flipping Horizontally (Mirroring) A Mesh...

This PR will add the mirror mesh feature command to OpenSCAD workbench. I had a short look at your pull request. FreeCAD has a paradigm in separating functions and gui operations, in order to allow call functions without the gui. This allows FreeCAD to run in server mode. So can you change your pul...

I should really post a feature request because in my opinion it's a little bit crazy that you can't do that... You can do just about anything else. You need to use python, than FreeCAD can do nearly all what you want. ;) There is the workbench OpenSCAD, which uses the program OpenSCAD to do operati...
