A fluid-handling cassette comprising a plurality of diaphragm valves and pumps is configured to have its actuation ports located along a thin or narrow edge of the cassette. Actuation channel % within the cassette lead from the actuation ports to actuation chambers of the valves and pumps in a space between plates that comprise the cassette. The individual plates have a nominal thickness that is sufficient to provide a rigid ceiling for the actuation channels, but sufficiently thin to minimize the overall thickness of the cassette. The cassette can be plugged into or unplugged from an actuation receptacle or a manifold by its narrow edge. A plurality of such cassettes can be stacked together or spaced apart from each other to form a cassette assembly, providing for a convenient way to install and remove the cassette assembly from its actuation receptacle. The arrangement allows for an improved way of connecting a complex cassette assembly to its associated pressure distribution manifold without the use of a plurality of flexible connecting tubes between the two.

A method of modifying CAD documents is provided, the method including use of a CAD modifying application that enables a user to modify a plurality of CAD documents outside of a native CAD environment. In another embodiment, the application may be integrated into a native CAD environment. The method includes using the CAD modifying application to build a workflow environment from existing CAD files, configure parameters and components of the workflow environment according to desired modification, and generating the modified CAD documents by instructing the CAD modifying application to communicate with existing CAD software.
