There comes a time in every fabricator’s life when they realize there’s an asymptote in the home garage. No matter how skilled you are with a grinder, how straight your hacksaw cuts, or how steady you can hold that hand drill, there’s an invisible line of quality and accuracy that you can approach–but never cross–at home. 

We’re talking about those …

Just drawing a sketch of what you want and putting some dimensions on it and making sure those dimensions make sense will got a long way to making a good looking fully functional part.

Learning what functions to use, what they are called, and which program buttons to push can be intimidating. Key is to commit the time to go at your own pace. Eat that elephant one bite at a time...

I'm happy to say that I almost never use technical drawings.  99.9% of stuff I work on is made directly from the cad, no drawing needed.

What we REALLY need an article about is how to print STRONG prints (layer grain direction, filament type, flexibility, etc). 
 

I can print things in Petg and ABS, but can I use it to make suspension bushings? How about sway bar brackets? Intake manifold? Air filter adapter? Oiling system components? Turbo brackets? Etc?

There's a big difference between making parts and making precision parts.  Precision parts need to interact in specific ways with other parts.  For precision parts you have two choices: make it yourself and customize it by hand with files and sandpaper, or generate a print with geometric dimensioning and tolerancing to let someone else make it.  Doing the design and making the drawings is as much of an art as making the final parts from the drawings.

Can you share a list of the YouTube videos you watched and found helpful. Thanks!

CAD is a technical drawing.  Just doing it with a computer, hence the name Computer Aided Drawing

CAD is Computer Aided Design.  It can mean many things, but often it is either 2d lines, 3d models, surfaces, etc.  Technical drawings are created from those designs.  We skip that part most of the time, and there is a general movement in that direction - see https://en.wikipedia.org/wiki/Model-based_definition

In the old days (1980s) when CAD was loaded via a 5.25 floppy and machines didn't talk to computers without punch tapes CAD was a drawing only tool for most of us.  The term for design to build was CAD/CAM. You can quote wiki all you want, I was there and none of my vendors had the ability to load a CAD drawing into any machine.  Th evolution was fast though.

it's not 1980 anymore

I thought CAD meant Cardboard Aided Design?

(JK I use CAD at work everyday)

Figured I should add my latest CAD project to this story. I needed a bracket to mount an oil pressure thermostat, and made it myself with what I learned writing this series.

Nice work.  What brake did you use to form that?  How accurate are your bend deductions?

I used the finest imported vise brake available on Amazon. And I'll admit I didn't check my bend deductions. I was in a hurry and it fit first try, but I should check them before I build anything real precise.

Well done sir.

Yeah, check them then put the math back into your software and you can build some super precise stuff... not that you really need to in this world, but its fun to do anyway.
