The Age of 3D Drafting

3D drafting of models using CAD tools brings life and clarity into the design objectives with respect to interference, clearance, tolerance aspects, aesthetics and helps communicate ideas more effectively.

The use of computer-aided design (CAD) has become commonplace during the past few years. More and more companies are moving to the 3D drafting because of its efficiency; not only does it save money, it improves customer relations too.

By using 3D Drafting, engineers can create better designs very quickly. 3D drafting is used in many industries, including manufacturing, research, engineering, architecture, media and entertainment.

In architecture, 3D drafting is especially useful since it allows architects, engineers, builders and clients to visualize interiors and exteriors of projects. Errors can be detected easily, and corrections be made quickly. It allows builders to visualize projects and optimize time and resources. A 3D model also helps clients to make purchase decisions easily.

In many industries, 3D drafting is no longer an option but a necessity. For example, you need to have 3D models in prototyping because most prototyping machines require 3D data.

Another advantage of 3D drafting is that it allows collaboration between engineers, clients and suppliers. 3D models can be viewed in real time over the Internet by many parties and corrections made when required quickly.

There are two basic types of 3D modeling. 3D "dumb" solids are created in a way analogous to manipulations of real world objects. Basic 3D solids don't usually include tools to easily allow motion of components, set limits to their motion, or identify interference between components.

3D parametric solid modeling requires the operator to use what is referred to as "design intent". The objects and features created are adjustable. Any future modifications will be simple, difficult, or nearly impossible, depending on how the original part was created.

There are many companies offering 3D drafting software. Some of these products include AutoCAD Architecture, ArchiCAD, Revit Architecture, Microstation TriForma, Google SketchUp, VectorWorks, Catia, ProE and Cinema 4D.
