Embodiment Construction

[0014] Embodiments of the present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the invention are shown. Indeed, embodiments of the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. The same reference numerals refer to the same elements throughout.

[0015] As noted above, various approaches have been taken to convert complex CAD models into simplified CAD model representations; however, most approaches are time and labor intensive and require significant manual input from the user. While some schemes for providing simplified CAD model representations have been proposed before, each of these schemes has significant drawbacks. Requiring a user to perform many operations manually in creating a simplified...

Abstract

A method for simplifying a representation of a computer-aided design model may include determining cavities within a three-dimensional computer-aided drawing model and closing the cavities (120, 130) with a closing feature (122,132) where the closing feature (122,132) is disposed at a predefined depth below the cavity opening. Determining cavities (120, 130) may include calculating the number of cavities within the model. Calculating the number of cavities (120, 130) within the model may include checking the number of internal loops present on the model. The method may further include generating a surface extract including an outer skin of the model, closing the outer skin, and filling the skin to create a filled solid body. The method may still further include generating a set of two-dimensional views of the model, each two-dimensional view from a respective viewpoint, where the set of viewpoints encircles the three-dimensional model.

Description

technical field [0001] Embodiments of the invention relate generally to schemes for providing simplified computer-aided design (CAD) model representations, and more particularly, to providing less detailed CAD models for use in operations that do not require the highest level of detail Mechanisms represented, such as the configuration or packaging design of components in a CAD model in a system such as a turbocharger configured with an engine intake and exhaust port. Background technique [0002] Computer-aided design (CAD) models of complex parts and assemblies can be very detailed, including limited detail of even the smallest components in the assembly. Individual parts of a CAD model may include detailed surface profiles, internal parts, or complex surfaces such as helical wire patterns. Large assemblies with many parts can result in CAD models having file sizes of tens of megabytes and causing CAD software programs to consume large amounts of memory when opening, manip...
