Mechanical Part in AutoCAD ©

Solid model in the three - dimensional Computer Aided Design (CAD) software AutoCAD © by Autodesk, Inc. Solid representaion of a bracket modeled via primatives, such as cylinders, and boolean operations, such as subtract. The 3D software part file contains information defining the solid, with an inside and a surface; this enables Finite Element Analysis to predict stresses and strains.

Fully Filleted Solid Model

A solid model part file can be used for Computer Aided Manufacturing (CAM) to define a Nurmerically Controlled (N/C) tool-path. A sand - cast part has rounded corners (fillets) as produced by the mold's top and bottom halves (cope and drag). This model has the corners (see next slide) filleted in the 3D software. Often the filleting command in the software fails; a structured approach will accomplish this filleting.
