QRec is a tool for automatic reconstruction of 3d models from engineering drawings. Current version is just a proof-of-concept and is not guaranteed to work on any drawings but the ones in the repository.

QRec implements a section identification scheme as described in [1]. For reconstruction of 3d solids a CSG-based method similar to the one described in [2] is used.

QRec takes input in dxf format. Currently it is possible only to display the reconstructed solid, not to save it.
