Ask HN: What CAD program is worth learning, if any?

#1
I've learned that in order to get what I want from graphic designers, it's really worth it to know Photoshop, even if I have no interest in being a PS monkey. As a corollary, can I plan ahead and learn the rudiments of CAD if I have aspirations of pursuing product development? Would that be a useful endeavor for a biz-guy?

I don't know that even your first point holds true, communication and the willing to compromise is what is probably most key.

CAD isn't really going to help you much unless you are planning on building prototypes yourself (even then you would probably end up having to start over if you hired someone else with actual experience.)

If you want to learn a program still, Solidworks is probably the most widely used, the two other big players for 3D are Pro/Engineer Wildfire (though I think they changed what it is called now) and Autodesk Inventor (not quite as used, also lacked major integration with FEA last time I looked).

Try solidworks. It's the only one I learned in engineering school but is really intuitive for a CAD (autocad sucks, but that's because it was hard for me and I never learned it).

Also sketchup will give you the fundamentals for free.

I'd say it is worth it to learn the basics of anything you'll be having employees do for you. It's good to know what you're asking for and the scope so that you can connect to your employees more easily. I wouldn't become an expert at it though if you are not planning on using it too much.

Yes it would be a useful endeavor. You will save hours of time on each new product. I would suggest that Google SketchUp is easier to learn (and free) but SolidWorks is very common in manufacturing. Doing a quick mockup in SketchUp is the new version of the cocktail napkin sketch, but with 3 dimensions instead of two. I recently used it to explain to a contractor how I wanted my bathroom remodeled (keeping my wife happy) and the time it save in discussions was immense. The contractor could immediately see what I wanted to do - move a wall, change a doorway, move a sink. Easy.

Make sure you learn how to specify dimension in SketchUp when you learn it. That will save you a lot of effort, and find video tutorials on YouTube. It was much easier for me to understand it by watching the video than by reading Google's documentation.

My boss does everything Visio. It imports and exports to CAD so we can communicate with the rest of the world. It might be worth looking into.

I dont know why you're being downvoted. I design in autocad, revit, sketchup, visio and inkscape.

I do network designs in visio, 3d BIM models in revit, small home stuff in sketchup, presentation graphics and icons in inkscape.

I export visio stencils to .dwg format which we then bring into revit and turn into 3D blocks for rack elevations etc...

There are so many tools to use.

May I suggest that you learn to draw. The old pencil and paper way. Technology marches on, but core skills will hold up well. You'd really communicate more effectively with visually oriented people if you can sketch on paper or a whiteboard to illustrate what you are trying to convey. You can always scan your work or use a tablet to create directly on the computer.

Take a look at Betty Edward's book "Drawing on the Right Side of the Brain". It's probably the best intro around.

As a "Biz Guy" your enduring quality and contribution is to hold the vision and communicate it effectively to the specialists, be they PhotoShop or CAD skilled.

+1 for SketchUp. It has many limitations but it so easy to get started with compared to the popular giants of 3d. Follow some of the tutorial videos.

It has a hugely active community writing custom plugins for just about everything you could imagine. My tipping point was finding all these plugins are written in Ruby :-) As a programmer I loved being able to hack together new extensions based on examining the source to other peoples work.

If you plan to do anything regarding animation, physics engines, or spline-based surface modeling etc then you'll need to look elsewhere of course. Blender is free and has a massive amount of features but a steep learning curve (and I personally dislike the interface).

If you want to do consumer products learn Solidworks. Once you understand and grasp it, it's amazing how quickly you can produce a product, I've gone from concept to prototype within a couple days. The important part is to learn what you can and can't do design wise (drafts, angles, thicknesses, etc), there are quite a lot of limitations but most can be worked around.
