Abstract: Computer-implemented detail propagation in a CAD model is disclosed. A detail and a reference base set comprising N?1 reference base solids are obtained via user selection. A detail volume to be replicated, encompassing the detail, is automatically computed. The detail volume comprises a surface and for each reference base solid a reference intersection curve of the surface and the reference base solid. A candidate base set comprising N candidate base solids comprising properties compatible with the reference base solids is automatically searched for. The detail volume is automatically mapped onto the candidate base set via a transformation. The mapping of the detail volume is automatically validated via the reference intersection curves. The detail volume is replicated, or replicating of the detail volume is suggested to a user via a visualization means, to replace the corresponding volume at the candidate base set according to the validated mapping.

Abstract: Based on user input, a detail and N base solids at or near the detail are obtained. A solid type for each base solid is obtained. A reference parametrization for the base solids based on the solid types of the base solids is obtained. The reference parametrization comprises one or more parameters and associated initial parameter values for the base solids. N target solids are retrieved which comprise properties compatible with the N base solids based on the reference parametrization. A spatial transformation and new parameter values for the reference parametrization which form a mapping between the base solids and the target solids are computed. An adapted detail is inserted at or near the target solids, or the insertion thereof is suggested via a visualization means. The adapted detail is based on the detail, the spatial transformation and the new parameter values.
