numbers of occluded parts. (ii) Handling fluids: While the
parts in most mechanical assemblies interact directly with
one another via contact relationships, some assemblies use
fluid interactions to transform a driving force into movement (e.g., pumps and hydraulic machines). One approach
for supporting such assemblies would be to incorporate a
fluid simulation into our analysis technique. (iii) Visualizing
forces: In addition to visualizing motion, some
how-things-work illustrations also depict the direction and magnitude
of physical forces, such as friction, torque and pressure,
that act on various parts within the assembly. Automatically
depicting such forces is an open research challenge.
