Just a quick introduction into the world of cad "computer aided design" I use cad in the design of mainly demolition equipment but it can also be used for 3d graphics 2d plotting and printing.
I do drop the odd graphics stuff in when I am just doodling to kill a bit of time or just to take me off some where else.
Turbocad is a very powerful piece of software, I do not sell it so don't panic just yet.
There are lots of cad programs out there so I can not compare it to anything else and as far as I know there is no formal qualification for cad as there are so many different types.
Grants are available in the uk to learn cad and if you are thinking of making any thing at all you should seriously consider learning some type.
We used to manufacture all the equipment that you will see on my blogs and it was a very tedious job indeed.
Why cad then ??.. Well once you have done it in cad you have it forever as long as you back your design up of course.
So I will leave it there for today as I am trialling some screen capture software which I hope to capture some screen shots from the user interface and will post them to one of my blog pages
