Yade

Surface creation and wire=False

Asked by Chandrashekhar Sirimala

I'm importing a geometry from .stl file using ymport.stl. It gives me list of facets, as shown below,

O.bodies.append(ymport.stl('cylinder.stl', wire=False)) #the geometry is cylindrical shape
I think this will make the facets into surfaces.
But when I'm applying rotation engines (i.e. revolving the imported cylindrical geometry), I'm able to see individual facets revolving.

how can I convert these set of facets into surface.

Hello,

It is always useful to attache / include minimal working example
reproducing your problem, it helps us a lot to solve it :-)

Currently there is nothing like "surface" in Yade, only list of facets..

in your specific case, I would say the problem is in RotationEngine
arguments. Did you use rotateAroundZero=True and zeroPoint parameters? see

Thank you Jan . Your suggestion to include rotateAroundZero=True and zeroPoint worked.
