Abstract: A mounting assembly is provided, including: a drive coupler shaped to engage a coupling member on a shaft positionable within a container defining an aperture to allow passage of the shaft; and a funnel positioned within the aperture to receive the drive coupler and guide the drive coupler to the coupling member. The assembly provides ergonomic advantages as the user is not required to lift the drive to reach the aperture.

Abstract: A computer-implemented method of geometric modeling to facilitate simulation for manufacturing operations is provided. The method involves causing at least one processor to receive signals representing a workpiece, and derive a workpiece model representation of the workpiece. Deriving the workpiece model involves identifying volumes that each include a surface of the workpiece, generating a plurality of volume elements for inclusion in the workpiece model, each volume element associated with a respective identified volume and representing presence of the surface of the workpiece in the respective identified volume. Deriving also involves determining at least one location on a linear boundary of a volume where the surface of the workpiece intersects the linear boundary, and, in response to the determining, generating at least one boundary surface element associated with the volume element for inclusion in the workpiece model. Other methods, systems, and computer-readable media are also disclosed.
