What CAD program did you use to render this?

Have you preformed stress analysis on that frame?

[ttldomination]

Very concise drawing. Lacks a little finesse, maybe try cardstock later.

Just a quick question, in this layout, is the chaining going on the outside of the chassis or on the inside?

With dead axles, I would assume that the chain would run on the same side as the wheels (outside).

[ttldomination]

Oh, did not real the part about the dead axles.

Looks legit.

Nice render. I find it very hard to believe that you didn't click the "make it pretty button."

Snarky. Although I am a fan of what your showing. We need to stop relying so much on computers to do all the work for us, and knowing how to do it by hand is always a good skill. However, technology is the future. The reason we have these things is so that we don't have to do it by hand anymore. We can have machines do stress analysis for us, saving us time of going though it by hand. However, the skill of calculating things by hand and sketching by hand is something that we should continue to teach the youth (until my netbook can run Inventor )

Yes, the stress did come preformed on the napkin. Upon analyzing it I found it quite pretty and it did an adequate of cleaning up the barbecue sauce.

I'm in total agreement Andrew.

One of the HUGE things that I think the cad monkeys miss out on (and I'm one myself now), is the gut feel you develop of how this stuff works out and the talent of visualizing this stuff in multiple views in your head.

Being able to close your eyes and actually see the views, rotate the components, and then say "yep, that'll work" rather than having to cad it is a talent that is only developed through use.

If you're used to sitting down and drawing something every time, you'll never develope the visualization skills to do it. Heck, I spend nights in bed when I'm falling asleep doing exactly this during first season. Especially with control board layouts.

This is a very good point. Since Ill be training a new CAD team over the summer, Ill try to emphasize visiualization before CADding.

I wouldn't say they all are missing it though. Most of my friends in CAD are equally competent sketchers, they just prefer the completeness you get from CAD. Maybe this has somethig to do with the fact that my school mandates a year of hand drafting before CAD.

I do think visiualizing ideas first is becoming a last art though.

Where's the "like" button?

For anyone else who enjoys detailed hand drawings like I do, I put up this thread a while ago that has some great resources in it.

I have two thoughts on the value of being able to at least estimate without CAD.

It is very easy to make silly mistakes while using CAD that cause results to be way off. It is quite useful to be able to recognize when things don't make sense.

It is also handy to be able to come up with sensible ideas quickly at the beginning of the build season or of a project at work when many decisions are made without the time to do the CAD.
