A system and method for reconstructing a 3D solid model from a 2D axonometric projection (line drawing) are described herein. The system comprises an interactive face identification module for identifying candidate 2D boundary loops for a user to selectively verify as corresponding to valid faces in the 3D solid model. The system further comprises an interactive geometry reconstruction module for reconstructing the 3D solid model from the 2D line drawing and validated boundary loops by iteratively receiving constraints from a user and propagating such constraints to the elements of the model following ranking rules to preserve significant symmetrical characteristics of the 3D solid.
