Acquiring 3 dimensional models of mechanical object from technical illustrations

Technical illustrations (TI) are one of the main methods to show a way to assemble/disassemble a mechanical assembly. The information including not only the shape of a constituent and an order of operations necessary to assemble/disassemble it can be driven from a single TI. However an additional TI is often required to further supplement insufficient information obtained from the single TI. The paper shows the solution required to resolve the problem which arises in augmenting a model description by unifying the results obtained from several TIs
