Generation of technical illustration from description of machines

Technical illustrations (TI) are always drawn in any assembly manual. This means that a TI is more informative than instruction in assembly tasks. Without TI, we have to read assembly instructions, it is difficult to infer a correct assembling procedure, if they explain several types of assembly relations. Even a novice can assemble or disassemble mechanical parts by only seeing a TI. But the order of assembly/disassembly is not uniquely obtained from a TI, knowledge on assembling operation will limit the order to plausible one. An assembly task is successfully divided into several easier assembly tasks than the original one. This means that a TI is composed of a set of TIs which are small and easy subassembly tasks.<
