Start With A Concept
I did all of my design in Solid Works for more than a decade. Recently I switched to "Alibre Design" it's now called "Geomagic Design". It seems to have basically all the features of solid works for a much better price. I recommend it if you are shopping around for a 3-D modeling software system
Isn't it beautiful!
This is a system I developed with Benny of Cool Neon and Funhouse Productions. It's a highly versatile all weather LED illuminated video display. This mechanical design allows the user to assemble their LED display on a series of bars or ropes. They can adjust the density of pixels by how close they put them together.
