Manual SU by my above method. I'm sure it's a little slower than fredoscale and probably a little harder. Took about 25 min. and I should be doing something else, but this is more fun.

You can draw a rectangle, divide it on the diagonally a bunch of times. figure out how many degrees around total the finished paper will be. The yellow one is about 28 sections bent at approx 15 deg. Bend in at a bigger angle alittle as you go will tighten the spiral at the end.

I worked on a similar 'Calcomp IGS 500' setup at the very same time - it was in the UK [it was the 1st CAD installation in England!]...
By the late 80s I was working on 'Silicon Graphics Indigos' using 'Sonata' [the grandpa of Revit]...

The digitizers were Calcomp, but the equipment was manufactured by a California company, which was purchased by GE around 1979.

1981-4 ?

Very good, I worked with this equipment from 81 till about 89, then Acad took over. This company is still using Acad.

1972? I wasn't alive yet...

Not that old.

"I'm not dead yet!"

I'm starting to model the office which I started my CAD career in.

Four 3D wire frame CAD stations running on a Data General Eclipse S120 (10MGhz, 1MG RAM I think), Anyone recognize the equipment or take a guess at the approx. year.

nice work there...
i like the ocean wave looks..
is it using sandbox tool?

Thanks Hussel,

Yes the waves were made using the sandbox tool. I just learned the sandbox tools for this project. Found a great 50 min video on youtube, from a Google Boot Camp a few years ago, with an architect explaining the sandbox tools. Great stuff.
