[cgma-dev] r4190 - in cgm/trunk: geom/OCC test

[Jiangtao Hu]

Hi, Hongjun

Now the code is changed for bodies to hold multiple volumes, it should be able to contain a body attribute. I haven't gone through this part of code yet. But I can work on it if you need.

Thanks for bringing up this topic.

Hello, Jane

I am developing parallel meshing and I need to distribute OCC geometry to multiple processors.
Since I am using Body as a unit of geometry distribution, I want to store distribution information as attributes to Body entities.
So, I made several import/export functions from/to memory buffer in "OCCQueryTool".

However, they are changed for "export_solid_model" function not to export parent Body entity of single Volume lump geometry
and I lose the attribute information assigned to Body entity.

So, can you change for single volume geometry to be exported with its parent Body attribute information?
Otherwise, do I have to use Volume and Surface as a distribution unit and assign the distribution information to Volume entity?
