AS Mechanical is a 3D mechanical hardware add-on for AutoCAD and AutoCAD-based applications. The software is said to allow engineers to quickly and easily create 3D nuts, bolts, bearings, and structural shapes. Because AS Mechanical 3D solids are parametric, bolt sizes, head styles, thread pitches, and beam sections can be changed at the touch of a button. AS Mechanical solids are designed to perform and respond exactly like native AutoCAD solids to ensure seamless file sharing. AS Mechanical supports AutoCAD versions 2000 through 2006 and vertical applications, such as Mechanical Desktop, Architectural Desktop, and AutoCAD Mechanical. Introductory pricing is $99.
