In modern architecture, using computer-aided design to develop structures and produce CAD design details for builders and materials manufacturers isn't a new technique. CAD has been around for almost 40 years, and has become an increasingly more important part of contemporary building and design. The ability to publish CAD design details in a standardized format has allowed builders and architects to share information like never before.

Many people recognize the earliest version of CAD to be MIT's SKETCHPAD system, which was produced in 1963. SKETCHPAD was the first computer system that allowed designers to input information into computers with a graphically-based interface, paving the way for the subsequent CAD design details and improvements such as automated documentation, automated inclusion of design assemblies, and verification of specs against a defined set of design rules. These developments in turn fed designer's use, aspirations and applications of CAD.

The CAD Design Details of Building Systems
In the last 30 years or so, building systems have become increasingly popular methods of residential building. A building system usually consists of a line of products that are designed to simplify construction in either the framing stage or the wrapping stage. Occasionally, a building system will cover both steps in a single stage, as is the case with ICF-based construction (insulated concrete form construction).

Builders who choose to use ICFS may be able to download CAD compatible files to determine exactly what materials they need. The files will help the builders break down the design into elements that fit into the building system's paradigm, analyze the necessary components, and determine the most appropriate installation and application methods. By making public the CAD design details of the building system, the manufacturer can promote their product through increased knowledge and simplified application.
