Abstract: Embodiments described herein relate to apparatuses and methods for generating face pair surfaces of a solid, including, but not limited to, identifying at least two face pairs including a first face pair and a second face pair. Each of the first and second face pairs including at least two face pair surfaces, graphically displaying the at least two face pairs, and receiving user input for at least one of (1) merging the first face pair and the second face pair, (2) deleting the first face pair, (3) adding a third face pair, (4) adding an additional surface to one of the at least two face pair surfaces of the first face pair, (5) removing at least one face pair surface of the first face pair, or (6) splitting the second face pair into at least a fourth and a fifth face pair, and determining at least one adjusted face pair based on the user input.

Abstract: Systems and methods are described herein for enabling direct modeling for a mesh model, including, but not limited to, obtaining a mesh model of a physical object, the mesh model comprising a plurality of elements, determining at least one feature associated with at least some of the plurality of elements of the mesh model, and manipulating the plurality of elements of the mesh model by manipulating the at least one feature.

Abstract: A method for simulating a physical object includes receiving user input to move an edge or plane of a simulated surface from a first location to a second location that is across an edge of the surface. The method also includes generating a visual display that is configured to inform the user that the movement of an edge to the second location across an edge of the surface is unpermitted.

Abstract: Embodiments are directed to a method for receiving a user selection of a first object of a simulated model and selecting a second object of the simulated model based on the received selection of the first object. The method includes generating an offset object similar to the first object, wherein the position of the offset object is based on the position of the first object and second object. The method includes generating a manipulation tool configured to allow a user to change the position of the offset object relative to the first object and second object. The method further includes generating a manipulation tool. The manipulation tool allows a user to change the position of the offset object relative to the first and second objects. The manipulation tool includes a first marker and a second marker associated with the first and second objects, one or more third markers that may or may not be associated with the offset object.
