The Building Information Model (BIM) is a new tool used by the architecture, engineering and construction(AEC) industry. The term Building Information Modeling (BIM) was coined byterm Building Information Modeling (BIM) was coined by Autodesk to describe "3D, object-oriented, AEC-specific CAD" and popularized by Jerry Laiserin as a common naming for these capabilities offered by several technology providers such as Autodesk, Bentley Systems, Graphisoft and others – a

There is a small investment of time to get your objects and or materials linked to a line item in the 'keynotes' file but the speed gain and consistency in standards is fantastic.

All REVIT components and materials can use keynotes.

Drafting viewsThere are three approaches to how we detail using drafting views.

templates ready for placement. We can also use File/insert from file/views.
