Computer Aided Design
CAD stands for Computer Aided Design or Drafting. CAD was developed in the early 60s. Today it is the premier way to design, develop and optimized products. People use CAD every day to design virtually every product you see. Generally, designers use CAD to design a product, and then produce prints to manufacture that product. A print is a picture of a part or assembly that is very exact. It includes the dimensions and a parts list used to manufacture a product.
U.S. CAD™ Chosen by David Evans and Associates
U.S. CAD™ Chosen by David Evans and Associates as Official Autodesk® Reseller and Civil 3D Implementation Consultant
Major engineering firm taps U.S. CAD to speed transition to new civil engineering software standard.
Costa Mesa, CA (PRWEB) January 22, 2008 — U.S. CAD, Inc. (formerly L.A. CAD), the Western U.S.’s largest provider of computer-aided design (CAD) consulting, training and support services, and its largest Autodesk® solutions reseller, today announced it has been chosen by engineering firm David Evans and Associates, Inc. (DEA) as its official Autodesk reseller and Civil 3D implementation consultant. The multi-year contract puts DEA at the forefront of engineering firms transitioning to the new industry standard in civil engineering software, with U.S. CAD advancing the effort.
"We are very excited about our agreement with DEA, which enables us provide them the latest Autodesk solutions, as well as our advanced training and support services — all aimed at helping DEA and its customers be even more successful," said U.S. CAD CEO Danny Counts. "This agreement exemplifies our U.S. CAD strategy to expand our technical capabilities and reach, while maintaining our core focus on delivering superior technical solutions and customer service."
"Over the past two years, DEA has been embracing and leveraging the new Autodesk Civil 3D technology through a large scale, phased approach," said J.C. Davis, DEA corporate information systems and Civil 3D project manager. "U.S. CAD has the resources and expertise to handle the ongoing administration and management of this project, as well as the ability to meet our other ongoing Autodesk product, training and support needs. It’s a good match."
With offices in Arizona, California, Colorado, Idaho, New York, Oregon and Washington, DEA is ahead of most other large engineering firms in implementing the new Civil 3D standard, which for many large-scale applications is the next-generation to Autodesk’s workhorse Land Desktop software. "Civil 3D is far more than a new civil engineering software application; it’s a fundamental advance in the field — a new way of completing projects faster, more efficiently and with greater design consistency than previously possible," said Davis. He added that DEA’s time savings on production plan development thus far using Civil 3D has approached 30 percent, with greater savings anticipated with through product familiarity and U.S. CAD’s support.
"With its ability to dynamically connect design and documentation, enabling design development to occur simultaneously with data collection, Civil 3D requires an organizational commitment to workflow change that many firms aren’t yet able to approach," said Melanie Santer, U.S. CAD applications engineer, who specializes in Civil 3D training, installation, support and implementation. "This is where DEA’s forward-thinking and U.S. CAD’s Autodesk and Civil 3D expertise make the perfect pairing. The end result will be time and cost savings for DEA and its customers."

Grow Your CAD Drafting Service Providers
If you work in a specialized design domain, such as aluminum composite panel assembly, HVAC duct installation, log cabin architecture or turbocharger manufacture, your CAD drafting service provider will need specialized knowledge for performing your drafting.
For instance, the drawings might have to be compatible with a CNC machine tool. This would imply a definite relationship between types of objects in the drawing and the layers in the drawing. This in turn would require the CAD drafting service provider to understand which objects to put on which layer.
Understanding which objects to put on which layer frequently calls for the draftsperson to profoundly understand your manufacturing or construction process.
The trouble is, there are very few CAD drafting service providers with ready knowledge of specialized domains. This means your choice of providers will be limited, and there is a good chance you will not be enthused by any of the firms that present themselves.
So what?s a CAD outsourcer like you to do?
Grow your own! (provider, that is?)
You?re right if you think this takes a lot of time, energy and patience. You?re wrong if you feel it will not be worth it.
Look at the advantages: we are talking about subject areas where there aren?t many good CAD drafting service providers. You take the trouble to develop one. So finally you have a good one and nobody else does.
This gives you a tremendous competitive benefit in terms of cost. While others have to use in-house, specialized draftspeople costing maybe $27 per hour, you?re cruising along at $11 per hour. Is that a killer advantage or what?!
The other big plus of growing your own provider is the loyalty that develops. Service provider loyalty is like protein to an outsourcing relationship. You need it vitally, you can?t buy it out and you have to produce it within the relationship. If you have it, you can go more miles than your nearest rival.
Which CAD service provider do you start off with? Find one your friends are using, or go online and select one with due diligence (more about that in a forthcoming article).
The motto of this story is that if you cannot find a CAD drafting service provider with the skills you need, find one that has an otherwise strong skill set. Take the time to teach them the skills, knowing all along that it is you, the outsourcer, who will reap enormous benefits as a result of the process.
To your CAD outsourcing health!

CAD Design for CNC
Design
First we are going to talk about the initial element of CNC. That element is design. Before you begin a CNC project, you need to have a plan of action. The design is like a blueprint, you know what you are going to build before you ever build it.
Here are some important elements of design that need to be answered:
What size will it be?
What material will it be made of?
Who is the customer?
What will it be used for?
Your design can be anything. It could be an industrial part or a work of art. This is only really limited by your imagination. Many people use CNC every day to manufacture parts. Many hobbyists use CNC every day to create art and various home projects.
Before I design I like to sketch a few ideas out on paper. I like to toy with different ideas to spark my creativity. This is the equivalent of brainstorming. When I really get my juices flowing, that is when my best designs rise to the top. I generally carry around a notebook with me to note designs that I think of during the day.
After I have a few likely suspects, I try to look through each of the ideas to see if I can merge them somehow. Some designs have different parts or components to them. Some of these components are better than others. Can I take some of these parts and add them to another design to make it better? Just like writing, editing your designs is a critical step in the process.
When you are designing, you are really trying to describe what you are going to build. The more accurately you can do that, the better the whole process will go. Just like a house, if you have a strong foundation, you will have a good house. If you have a solid design, the rest of the process is easy.
CAD
CAD stands for Computer Aided Design or Drafting. CAD was developed in the early 60s. Today it is the premier way to design, develop and optimized products. People use CAD every day to design virtually every product you see. Generally, designers use CAD to design a product, and then produce prints to manufacture that product. A print is a picture of a part or assembly that is very exact. It includes the dimensions and a parts list used to manufacture a product.
Computer Aided Drafting software packages can generally be broken into two groups. The groups are 2-D drafting packages or 3-D drafting packages. Most all software packages are moving to 3-D design. 3-D design is really the next generation of CAD. Utilizing 3-D design, engineers can make a model of their product. They can then look over this model for any apparent defects before it is ever made.
3-D Design
Utilizing 3-D design, engineers can cut down on the number of manufacturing mistakes that occur due to fit up and tolerance issues. This translates into a more efficient operation with less waste for the manufacturer.
Here are some examples of 3-D drafting/design software:
Inventor
TopSolid
SolidWorks
Alibre Design
Rhino3D
2-D Design
2-D design can be very efficient if you need to make a quick part that is not very complex. You could quickly sketch out a silhouette of an object and convert it into a CAM tool path. This is an operation where 2-D will really shine.
Here are some examples of 2-D drafting/design software:
AutoCAD
MicroStation
At some point you will need to use CAD. You will need to take your design and translated it into a print. The best way to do that is to use CAD. You will need to purchase a CAD program of some sort if you are serious about CNC. Many CAD programs have a free or trial period that you can use to evaluate the program. My suggestion is to try a few and then select one that fits the way you design.
