Question #247095 on Yade changed:
https://answers.launchpad.net/yade/+question/247095

Hongyang Alex Cheng proposed the following answer:
Hi, Mayank

Here is my approach. Hope it could give you some hint.

I used autocad to built the predicate and output it as an stl file.
Using 'stl2gts' my stl file was converted to the gts file which can be
imported into Yade.

As for preparing spheres using predicate as boundary, you can always use
the function 'pack.filterSpherePack()'. Bruno Chareyre's suggestion in [1]
will definitely help.
