FastSOLID is an ACIS based solid modeler.

FastSOLID includes modeling with primitives such as the block, wedge, prism, cylinder, sphere, cone and torus.

FastSOLID recognizes FastSURF surfaces.

FastSOLID can create solid bodies from CADKEY wireframe models.

FastSOLID blends solid edges using fillets and chamfers.

Rounded corners can be blended with multiple converging fillets of different radii.

FastSOLID can read and write .SAT files and IGES surface files.

FastSOLID can render solid images to the screen or write to bitmap files.

FastSOLID calculates mass properties.

FastSOLID performs boolean processes like unite, subtract and intersect to compose more complex solid bodies.

FastSOLID writes stereolithography files for rapid prototyping.
