A look at CAD not that long ago
« on: Wed, 16 October 2013, 13:02:18 »
Didn't know if I should post this in DIY as it concerns CAD and also input and user interfaces in general. I thought it might be of interest to some around here.

Weird, there is audio there for me. Tried another device?

I wonder if they knew that they would define construction and mechanical design for decades to come and likely century. Such a simple thing like calling it a constraint or the snapping for instance. Very little has changed and they truly revolutionized the game. I find it fun to see how oblivious they appear to just how large of an impact the things they are describing will have on modern R&D.

As someone who did CAD/CAM design work for 3 years, and hated it, that looks so terrible...

God bless everyone who suffers through CAD/CAM work.

You do realize that this was done almost 50 years ago when programming was done with punch card.  Also the monitor they were using was actually an oscilloscope so the resolution isn't going to be perfect.

I showed this to my wife and she was impressed by what they had come up with this long ago.

Just wanted to let you know I showed this to a friend of mine that is doing a paper on input tech.  He thought it was awesome.

Sutherland’s Sketchpad is one of the most important and influential computer programs of all time (and one of the most influential PhD theses in computing; later, he won the Turing award for it and his later work). Its abstractions for defining geometric relationships and constraints is breathtakingly ambitious, and I highly recommend that anyone interested in user interface design or the power of computing study Sutherland’s thesis and think hard about the ideas embodied in the program. https://en.wikipedia.org/wiki/Sketchpad

You hardly even need to look at Sketchpad. He nailed it on the first try and a lot of it has remained in modern CAD software. He really really understood exactly what is required, what tools the user needs and how the user should interact with them.

That's pretty astonishing.

I work in CAD every day and I quite enjoy it most of the time.

"until I tickle that toggle over there..."

I thoroughly enjoyed watching this, thanks for sharing! Very impressive for the era.
