Thousands of huge printed sheets depicting engineering drawings keep record of complex industrial structures from Oil & Gas facilities. Currently, there is a trend of digitising these drawings, having as final end the regeneration of the original computer-aided design (CAD) file, which can be better visualised and analysed through diverse computer applications. Most efforts in literature and commercial applications have focused on converting these sheets into CAD files in an automated way. Nonetheless, this needs to be a zero-error process; as the final CAD will always be verified by an engineer for integrity and inspection. In this paper, we present a method that, on the one hand, highlights which components in the CAD are most likely to have been incorrectly identified, and on the other hand, facilitates the engineer to search some groups of components in these huge assets. These techniques are based on graph embedding, computer neural networks and sub-graph matching.
