Easiest CAD to learn to layout my chassis?
Is there a relatively easy to use basic CAD program I can buy to layout a pair of mono block amps? I will be using the Welborne wood boxes. I am trying to find the easiest CAD program for me to design a very basic layout. I can either build a 300b, or a 2A3 pair of mono block amps. I have the iron, all I need is to be able to layout a chassis to have a metal shop make me the top plates. I will be using the Angela power tranformers. This way I can paint them green to match the Tango and Tamura iron. I have Tango XE20S output transformer, and Tamura 10H chokes. Both have a rather unique pattern to be mounted on a chassis. If I tried to hack it in myself on the top plate it would look very sad. So which CAD has the lowest learning curve? All I need is a very basic CAD package to be sure.
Thanks in advance! John C. Framingham, MA

not CAD, but does the job for me, including schematics too - Visio.

SketchUp is really easy to use, but you can't make curved faces etc.

If you want something really nice, try SolidWorks. It's amazing really.

Pencil, paper, square and ruler. No joke... it is not only the easiest, but if you are making one or two-offs, then it is not only the cheapest, but the easiest. Oh yeah... and eraser.

No joking, many high tech prototypes were designed this way and given to a CAD jockey for "proper" drawings. In fact, just about all machine and wood shops that I know will still work from this "file format."

I've tried out Front Panel Designer for my power supply chassis top-plate...
It only took me an afternoon to master the thing!

I however am still having problems with the curvature of my PIO capacitors :rolleyes:
I think I have a corner radius of about 0.8091" however I'm unsure!

I'm not in the USA but I'm hoping they will accept sending it to a custom shipping company for postage to here...

I may have to shoot off for a sample or a 'cheap-make-sample' :)
Other than that this application and 'design-n-buy' process is kickass :smash:

Take a look...

They are Sprague brand with 2 3/4" wide, 1 3/4" thick dimensions.

Anyone got a clue what the exact corner curvature is in inches?
