Methods for product data management and corresponding systems and computer-readable mediums. A method includes receiving a geometric model including plurality of entities and receiving existing conditions corresponding to the geometric model. The method includes receiving an operation to be performed on a selected entity of the geometric model. The method includes propagating through the geometric model from the selected entity to other entities of the geometric model, according to the existing conditions, and adding the selected entities and the other entities to a variational system. The method includes performing a variational solve of the variational system according to the operation to produce modified entities and applying the modified entities to the geometric model to produce an edited geometric model.
