you’re a person that deals in any kind of design business I’m sure you’ve heard the phrase CAD somewhere or have seen it in some sort of literature.

What’s CAD & CAD Software?

The letters in CAD represent the acronym for Computer Aided Design or Drafting. This is designing technical drawings with the assistance of computer software. This software has been around for a while now,and has eliminated its prehistoric counterpart the drafting table. The practice of using a drafting board to design blueprints is still used today, but has nowhere near the presence it once had. In most of the world CAD has replaced this old form of creating technical drawings, and has allowed drafters to complete 3D designs in less than half the time it once did.

CAD Software

CAD software can be installed on almost any PC or laptop as long as it meets the general requirements of the software. Instead of creating straight lines with a ruler CAD has a simple command that allows the line to be inserted into the drawing by either clicking the mouse in the appropriate place, or by manually inserting the length of the line along with an angle. CAD is extremely precise, so you don’t have to worry about drawing a line to big or small.

Here is a video that demonstrates how CAD is used.

This software also has tons of other commands that allow a wide array of different lines to be created.
One advantage to CAD is the ability to perform 3D commands and give a 2D image 3D characteristics. This is usually done by adding an orthographic view to the blueprints which allows the person interpreting the design to better understand what he or she is looking at. If you were designing your technical drawing on a set of blueprints it would take several hours or days to completely freehand the design, and it still wouldn’t be as precise, or have the detail within it compared to a 3D Model that was designed with CAD software. The fact of saving time is only one of the many advantages CAD programs have over the traditional way of drafting.
CAD is not only for one or two specialties of drafting, but instead CAD has a separate program for each one of the design fields including:

  • Architecture
  • Mechanical
  • Structural
  • Civil
  • Electrical
  • Inventions

In a few years from now there will be no more paper blueprints except for use in the field. CAD is the next step in the evolution of design and will continue to become more complex, and contain more tools for design as time progresses.
