BIMĪutoCAD is used to convey design intent, by utilizing Lines, Arcs, and Circles, to illustrate the design. * AutoCAD is available for MAC, whereas AutoCAD Architecture and all other products in the Specialized Toolset only have compatibility with Windows. Since all AutoCAD functionality is available within AutoCAD Architecture, you get more in almost every way*. AutoCAD Architecture (ACA), which is one of the vertical products available with AutoCAD Including Specialized Toolsets, has all of the same functionality as AutoCAD, plus the addition of tools designed for Architects to enhance the workflow of construction documentation. Depending on your needs, you may require more features within AutoCAD (ACAD) specific to architecture, design & documentation. In a previous post, we talked about the differences between AutoCAD and AutoCAD LT.
