It's Summer Here, How About Designing some Ice Cubes?

 

By the way I'm a Mechanical  Design Engineer. And I was pretty poor at designing. And I feel this is pretty easy way to learn to design things. 

My Mantra towards designing things is (if you're not a pro), start with pretty basic geometry and build from there. Since you'll be building things only virtually, you shouldn't be wasting any material or energy.

So, for the first tutorial let's move on with designing an ice cube. My choice of CAD software for accomplishing this would be Autodesk Fusion 360.

Being a simple person and also a math fanatic, I start with simple geometries.. something like below.



The next step I will be doing is to taper all the sides with a draft of 15 deg. After the modification the design will be altered as below. Fusion allows us to do this by rotating the side faces about the top edges by means of a Mystic Wheel



Note: There is another way to achieve the above design, by Lofting the above and below face sketches. And the reason for not adopting this method is you won't be having the final design in your mind as a designer. You just tweak an initial idea and keep improving on it until it becomes perfect and usable.

The last step would be adding fillets and chamfers wherever required. The fillet radius will match the radius of the corresponding container. And also, engineers dislike sharp edges but we just go easy on them today.




Well, you can always add colors and textures to suit your taste ;)



Well finally, these are the final cubes we have at our disposal, obtained by using rectangular pattern. The lighting conditions are not perfect otherwise, these would sell like hot cakes.

Design Speed - How Fast you can Design

Analogy.. How fast you can speak depends on how fast your thoughts are (flow of thoughts) and.. how long have been Fast/Articulated Speaking. How fast you can type depends on Muscle Memory and.. Speed and Dexterity of fingers. Similarly, how fast you can design depends on your ability to manipulate 3d thoughts in your head and.. Familiarity with CAD software interface. First one is mental ability and second one is skill (which comes with practice) The latter can be improved within short time. But the former..

Writing vs Designing

Both Writing and Designing are Creative fields.  For (Creative) Writing to happen, one should Read extensively. Have their fair share everyday. Similarly, to create (Great) Designs, one should feed themselves with other Designs. It's not about reproducing the same content. But, mix and matching the intrinsic features to create a completely new creature.
