METHOD FOR MANIPULATING A COMPUTER AIDED DESIGN (CAD) MODEL BY A DRAG OPERATION, A COMPUTER PROGRAM PRODUCT AND A SERVER THEREFORE

摘要

In a first aspect the present invention provides a method for manipulating a computer aided design (CAD) model, comprising the following computer- implemented steps of: - creating a first solid entity in a CAD model, said first solid entity comprising one or more coordinates and a 3D volume; - a user executing a drag operation on said first solid entity; wherein said drag operation comprises the following computer-implemented steps: a) selecting a face of said first solid entity; b) determining if said face is a major face or a minor face for said first solid entity; c) determining a drag direction; d) in case of a determined major face executing a moving operation on said first solid entity in said drag direction and in case of a determined minor face executing a push-pull operation on said selected face of said first solid entity in said drag direction. In a second and third aspect, the present invention relates to a computer program product and server for manipulating a computer aided design (CAD) model by a drag operation.
