I haven't followed up. When I last looked, I found the problem space is too large for one person (or project) to do it all. So the job is to glue together lots of good OSS tools -- which is a very pythonic task. The absolute requirement for Knowledge-Based-Engineering is an API which allows a script to do anything a human can do. E.g.:
1. For 3D mechanical CAD, there is OpenCascade, with the pythonic freecad frontend. http://www.opencascade.org/ http://juergen-riegel.net/FreeCAD/Docu/index.php?title=Main_Page OpenCascade requires registration and is big download. 2. For 2D mechanical CAD, there is PythonCAD http://www.pythoncad.org/ The explicit intent to provide full scriptability (anything a human can do via the GUI, a script can do via the API). 3. For EE schematics and simulation, there is OpenCollector and specifically gEDA suite. http://opencollector.org/ http://www.geda.seul.org/ Not pythonic, but people have written glueware scripts in python to tie the pieces together. 4. For fancy 3D objects and animations, Blender has the power and is scriptable in python. It comes from the world of animations, but the math doesn't care if you do EE 3D models instead. http://www.blender.org/ 5. We should all be concerned over SGI selling the OpenGL patents to Microsoft, so at least look to Mesa, and perhaps to alternative 3D libraries. 6. I don't do GUIs much, but I understand form others that PyQT's slot-and-signal architecture is well-respected, that *many* OSS projects use PyGTK, and that folks who use wxPython are looking at "wax" as a more pythonic layer. I finesse the whole issue by claimintg "GUIs are for humans to do the work. I write code so computers can do the work." :-). > -----Original Message----- > From: Dan Fabrizio [mailto:[EMAIL PROTECTED] > Sent: Saturday, May 26, 2007 3:46 PM > To: python-list@python.org; George, Harry G > Subject: Using python for a CAD program > > Hello, > > I saw your post from last year about using python for a EE > CAD program.
