Reduce Development Time

Leverage the APIs in CGM Polyhedra, such as those for Additive Manufacturing data preparation, to quickly add new workflows to your application saving time and development cost.

CGM Polyhedra's Features Include:


Spatial's polyhedral solution supports customers' many data sources including medical data, terrain data, scanned objects, raw mesh data, precise models and dozens of 3D modeling formats when combined with 3D InterOp.


CGM Polyhedra automatically repairs models where other solutions fail. Combined with evaluation adjustment and repair tools, this enables you to product models that meet manufacturability specifications.

Polyhedral Operators

CGM Polyhedra offers many APIs to enable building data preparation workflows such as Booleans, Offsets, Decimation and Slicing. CGM Polyhedra allows for Booleans of polyhedral data with exact data to obtain a final polyhedral model.


CGM Polyhedra supports a wide range of topological queries and calculations such as wall thickness analysis, point-body-distance, extrema, mass properties and silhouettes on polyhedral models.

Uniform Interface

CGM Polyhedra and CGM Modeler share common polymorphic APIs for many operations to make implementation easy while using specialized algorithms optimized for the input data. The body data type can be either exact or polyhedral allowing data to be stored and managed in the same container streamlining code.

Additive Manufacturing

CGM Polyhedra offers a complete workflow for additive manufacturing data preparation such as wall thickness analysis, offsetting, orientation & nesting and slicing enabling faster time to market.
