Re: Why does this extrude fail check geometry?
In my rather limited experience I find that the very common BOPAlgo_InvalidCurveOnSurface errors often do not cause problems. But most of the other BOP check errors are important. +1 But this is very limited experience too. Sorry if this is 'thread highjacking', I took a deep dive on the BOPAlgo_In...

Re: Recurring problems with step data from step tools
Hello dear forum members, Again and again I encounter problems after importing step data into Freecad that was exported via Steptools. I look at the header of the file, if it says Steptools I know I'm in for an adventure. The data has errors in the surface boundaries, are surface models and not sol...

Re: bopalgo_invalidcurveonsurface error
Hi Can someone shed some light on this Geo Check error message? What exactly is the problem and how can it be solved? I did a deep dive recently on this. Basically, BOP thinks the tolerances of edges is to small(tight). BOP has a different method for deriving the edge tolerance value than the rest ...

Re: Weekly 021-31527 TechDraw dimensions cause crashes
I believe 7fc59a68a0 fixes this, but I don't have the ability to test on mac. Using the "sanitizer" I was able to generate a failure on linux at the same point as was reported for mac, so fingers crossed. I was fighting a heisenbug in occt. Wouldn't trigger a segfault with gdb and debug b...

Re: How to do something to improve the performance of FreeCAD?
That looks like OCC. There probably is not much to do in the code itself, but may-be it's possible to multithread it, so that different objects can be recomputed in parallel on multiple cores. Since they are independent OCC objects that are linked together in 3D space by the scene-graph (Coin3D) th...

Re: dependencies in the document xml, question.
This doesn't (necessarily) violate the DAG. When writing a feature to the Document.xml file then it also considers hidden dependencies but for a recompute the hidden dependencies are ignored. Ok. I guess I missed the fact that the dependencies are fully defined in each object and that "ObjectD...

xml schema for freecad's xml documents
Is there, or has anybody ever made, a xml schema file (.xsd) for the freecad xml documents?
