Lecture Autodesk inventor Solid modeling Swept solids

The chapter outlines the most common approaches for generating 3D computer models, in addition to how these models are viewed and modified on the computer. A particular focus is put on constraintbased modeling and its relationship to documentation, analysis, and manufacturing technologies.

Solid Modeling - Swept Solids Swept Solids Solid primitives can also be created by:  Extruding  Revolving  Sweeping an existing two-dimensional closed object The closed two-dimensional objects are called closed profiles All primitives can be created with a sweeping operation Extruded Solids An extrusion is a: Manufacturing process that involves forcing a material through a shaped opening Modeling process that creates a 3D shape by translating a 2D profile along a linear path AutoCAD Extrusions To create an extruded solid in AutoCAD:   Create a close polyline in xy plane of current UCS Extrude polyline in z direction of current UCS NOTE: AutoCAD command - EXTRUDE Revolved Solids A revolution is a modeling process that creates a 3D shape by revolving a 2D profile along a circular path NOTE: AutoCAD command - REVOLVE Sweeps A swept solid is created by moving a 2D profile along a path NOTE: In AutoCAD, a sweep is created via the EXTRUDE command, using the Path option Solid Modeling - Swept Solids Hasta la vista! ...
