GM on OCC6.3 capabilities

1.	Query

•	Import/Export OpenCascade  b-rep files, create CGM geometry/topology entities.

•	Import/Export OpenCascade b-rep plus CGM attribute files.

•	Delete entities build on OCC engine.

•	Translate/Rotate/Scale/Reflect objects.

•	Detect body overlap

•	Get iso-parametric points on surfaces and curves.

•	Get curve-curve, curve-surface intersection points.

•	Get distance between entities.

•	Get bounding boxes for entities.

2.	Modify

•	Create CGM geometry entities using OpenCascade engine. Top-Down method: directly create points, curves, surfaces or solid primitives.

•	Create CGM geometry entities using OpenCascade engine, Bottom-Up method: curve generates by points, surface generates by curves and solid generates by surfaces.

•	Boolean operations: subtract, unite, intersect.

•	Project curve on surface

•	Imprint object: body-body imprint, surface-body imprint, curve-surface imprint.

•	Make thick body by hollowing existing solid.

•	Sweep surface or curve along a vector, an edge, perpendicularly or revolutionarily.(alpha testing)

•       Section, cuts in half. To see a cross section of the model.
