TOLERANCES
If tolerance is not given, exact measurement of the parts must be made. Rejection rate will be very high and is not realistic.
Same parts can be made from different companies and they have to be interchangeable. Tolerance ensures good quality control for parts from different companies
The range of tolerance will translate into the manufacturing method needed, since different manufacturing method has different degree of tolerance.

ASSEMBLIES
-ASSEMBLY MODELLING. multiple parts are brought together to define a larger, more complex product representation. Assembly modelling facilitates the collaboration among designers, engineers, manufacturing technicians and others to ensure a product assembly works.
how it works?
begins with bringing in a base component, selected because of its central role.Each component brought in needs to be oriented and located relative to other components in the assembly. Assembly joints are used between elements of components.
