If tolerance is not given, exact measurement of the parts must be made. Rejection rate will be very high and is not realistic.
Fit
In clearance fit, there would still be an allowance for two parts to move, such as in a door hinge.
In interference fit, it would be difficult to move (or remove) the two interfacing parts. Usually, a lot of force is needed to remove the two parts. Examples are shafts that are fitted through bearings, so that the shaft does not slip.
multiple parts are brought together to define a larger, more complex product representation
In Fusion 360, multiple parts can be created and assembled in the same file. In many other CAD software, there will be individual part files, and an assembly file to place all parts together.
