The first links well deserves to be mentioned in this forum, but the second lets me rather assume this is a spam post .

I don't think so.
It's interesting to see how simple the methods of matthek are.
Maybe some of these ideas can be implemented for design tasks.

Die Datei hat Fehler, deren Ursachen ich mittlerweile kenne. Der eine Fehler ist unten bei den Füßen. Extrude hat sich nicht dran gestört, aber es ist eben kein Solid. $dp_027.png Man muss die benutzte BSpine anders berechnen. Da liegen ein paar Punkte zu eng beieinander, was zu diesem Haken führt. ...

It's named what it's named!

Stop whining - start coding! (the mantra of jriegel)

I'm looking for a free version fo the Step 242 specification
At the moment I use http://www.steptools.com/stds/stp_aim/html/ to read
but for automated processing of step data it wqoukld be nice to have the schema as a file and read it by a parser

Auf der einen Seite gelingt ein boolscher Cut, mit den beiden Würfeln leider nicht: Freecad braucht eine Reparatur-Workbench für Step Daten. Unbedingt. Wir müssten wissen, wer diese Fehler verursacht. Liegt das an den Step-Daten - Abweichungen vielleicht zu groß oder an den daraus generierten FreeC...

Interesting.

You can have a look to a test website (try to avoid breaking it) on https://justyour.parts.

How to register?

The converting of a brep shape to a mesh approximations is not unique.
If you use different ways you will get different results.
A mesh is always only an approimation. That means that the points of the mesh are near to the real points of the shape within
a defined tollerance.

An alternative might be the StepClassLibrary (SCL) where as far as I understand you can define some rules how to read a STEP and from these rules generate the source code. JRiegel once added it to the Import module https://github.com/FreeCAD/FreeCAD/tree/master/src/Mod/Import/App/SCL but it never r...

I loaded one of these files into my database without problems.
I see all the data
So the question is: why freecad cannot import the data?
I think there can be a way to import the entries and create an internal model and render the details.
