CSGModel

class compas_gmsh.models.CSGModel(tree, name, **kwargs)

Bases: Model

Model for shape generation through Constructive Solid Geometry.

Parameters:

treedict

The CSG tree as a dictionary mapping operations to operands. The operations have to be one of {"union", "intersection", "difference"}. The operands have to be lists of shapes or lists of dicts that are CSG trees themselves. At every level of the tree, there can be only one operation.

namestr

The name of the model.

Attributes:
