Reverse Engineering: Hobby Electronic Part 02

-

 


Continuing on with this reverse engineering project, I was able to very quickly craft the nuts that went with the screws by extruding a hexagon and using Boolean Difference with the already made screw in order to create the threads.  



The next piece I chose to make for my object were number 4 & 4.1. These two pieces were close to being the same but did have some different details, one being a female and and the other a male end, along with some exterior differences. 




These were designed by taking measurement after measurement with my digital caliper and applying the surface design as far as I could take it. After completing the first one I then went back and reused the geometry to build the second one. 


This was the conclusion of this work space.


Starting in a new Rhino file I began working on the ear pieces, 8,9 & 14.





Piece #14 was probably the trickiest one. because its a shell I set up my geometry and tried to loft it. Unfortunately the curves weren't creating surfaces the way I wanted them to. I then tried a tool, surface from 2,3, 4 open curves, and was able to get a better result. Using FilletEdge I could achieve the rounded corners I needed and then offest the surface in order to get the thickness needed.  




Piece #8 with the venting was mostly a matter of creating the geometry and extruding the curves to the correct height. Piece #9, the cushion that presses against the ear, is a very soft organic piece. The inside is made of foam and is easily influences so I used the geometry made from the other two parts as a frame to build this one around. Creating extrusions with the geometry I made a solid and then used fillet edge for the desired rounded look. Last I made the lip on the interior which holds the three parts together.  




This is the conclusion of this workspace.

BUILD IT AND THEY WILL COME said no one In the final chapter of this project I built the last 7 pieces of my object in rhino. 1,5,6,10,11,13 &14 5,11,12,13 5, 11 & 12 were very simple and mostly involved using sweep1. 13 was some simple surface designing.  1,6,10 Piece 10 mostly consisted of surface design.  Piece 1, the plug, required a more creative approach. The plug had these alternating negative shapes going up the shaft that were like little corners that were cut away, accept the tip of each corner was cut off to make the space for where the wiring goes.     In order to achieve this patterning I lined up square chips in the pattern that they appeared on the plug, then boolean differenced the cord itself and used what remained to boolean difference the plug in order to recreate this pattern. After completing all parts of the object I was able to put the pieces together. To render I used keyshot. I ran into an issue where the foam piece of the headph...

HAIR In order to make the hair I learned how to apply a curve to a path. I could do this by selecting the path, going into the data tab, geometry, bevel, object, and using the eyedrop tool, select the curve shape that I want applied. I could then scale the different points along the curve with alt + S to close the ends for the pointed shape, as well as widen and narrow the strands. All of her hair is made with the example on the right. the left is her eyebrows. To make her ears I created a plain using shift + A, subdivided it and shaped it using editing and modeling tools. I then added a thickness modifier.  The horns were made with a cylinder that I extruded (edit mode) into the shape from the beginning to end of the horn. I applied subdividing mods and used modeling tools to refine the shape.    To sculpt the face I followed along with this tutorial:  https://www.youtube.com/watch?v=BPAvvF8py1M&ab_channel=CGBoost starting with a sphere, as if it were a ball of ...
