As always, ok I will delete it .. never pass anything.
It is my fault I see you FreeCAD as my family and talk here. Last post ever.

I googled "opencascade documentation pdf" and found this: https://documentation.help/Open-Cascade/documentation.pdf It looks like it's for 7.2.0 and the latest is 7.7.0 -- so a little old. Great, thank you very much. This help me now and for the newer version we will see. Thanks you again.

Their home site says that you have to generate it and I don't want to download 1Ton program to generate just that pdf.
I appreciate if anyone konw where I can find or has it so I can get it.
Thanks.

It is time to understand all these API:s :roll: 1. 'Area' 86. 'extrude' 2. 'BoundBox' 87. 'findPlane' 3. 'CenterOfGravity' 88. 'fix' 4. 'CenterOfMass' 89. 'fixTolerance' 5. 'CompSolids' 90. 'fuse' 6. 'Compounds' 91. 'generalFuse' 7. 'Content' 92. 'getAllDerivedFrom' 8. 'Edges' 93. 'getElement' 9. 'F...

But I think I am trying to get that for the surface .. not the whole object

See how this shape fails in retrieving information that is found on other shapes. CenterOfMass, normalAt, ..etc all these are missing .. reason? Don't know really. The difficulty comes when you don't know when and why that is happening. I need to make many if to just fix that API issue. Standardizin...

What I read before, FreeCAD cannot have any multi-threading due to OCC. Single-thread means you are not using computer's capability at all.

Coin3D is old also. So, Might be also a source of trouble.
