Reverse Engineered Object Final

This is the final product for my Reversed Engineered Object Project.  I chose to reverse engineer a Lego Minifigure because of my love of Lego and all the different moving parts that fit together.  I used a digital caliper to record all the exact measurements and then transfer that into Rhino. For the most part it went quite well, the easiest pieces to model were the the head, torso, hands and pelvic block due to the fact that they are made up of simple geometry resulting in mostly squares and cylinders.  The hardest objects to model were definitely the arms and the hat because of their more organic like nature of the objects.  I had a few issues with the gun but only in the bend and to get that correct fillet in on the gun became quite process, something that I honestly thought should be quite simple.  The rest of the project fell together nicely and I definitely had a lot of fun working on it.

3D Printed Ring Design Progress 1

For the first week I am just playing around with shapes and seeing what I can create or what comes to mind. Most of the ones that I have now are just basic shapes, I was interested in playing around with rebuilding surfaces and warping them with points.  Flow along surface was another command that I was also playing around with. However I did have problems with Boolean unioning the objects so that they are water tight. I tried many different ways of cutting the objects and trying to rejoining them but that did not seem to work as well. Hopefully this will be figured out by next week.  I did however manege to create a few rings that are completely watertight.  I will possibly add a few more models but, for the most part I need to add more detail with rings I have. 

Reverse Engineered Object Progress Week 2

From last weeks problems, I did manege to fix the arms and get them more Lego like.  I managed to fix this by doing a combination of the sweep and loft commands to get a more accurate representation. After completing the arms I moved onto the hands which I have two different versions, which neither are 100% accurate.  I need some feedback before I decide which one works best for the project.  The gun was somewhat tricky to get the perfect bend in the handle.  I did manege to do it, however I could not get everything to Boolean union together, especially at the bend.  The last problem I ran into was exactly how to model the cowboy hat with its organic curves.  As you can see, I got part way there but it just became way too complicated for me that I just could not continue.  Looking forward to getting these problems fixed as the hat is the last project to model.

Reverse Engineered Object Week 1 Progress

Modelling a Lego Minifigure is fairly straight forward utilising basic shapes put together to form the figure.  So far I have modelled the basic shapes of the head, torso, pelvis and legs of the figure yet a few of them still need some slight touch ups and a bit more detail if possible. There are a slight change in the leg width and the pins for attaching the legs as well that still needs to be applied. Although my next step is to complete the basic shapes of the whole figure. I however had a lot of trouble modelling the arms and getting the transition of shapes to be smooth with the right angle. I tried a few different things but none of them seemed to work quite well. I first tried to make it in two separate extruded circles, then a loft through 3 different circle and lastly a sweep.  The sweep is best looking so far, however I could not get it to change diameters within the sweep to meet correct size of the piece. This is definitely something that I will need help and try figure out, hopefully it will be sorted by the end of the week.

Reversed Engineered Object

 I chose a Lego Minifigure as my object to reverse engineer in the Rhino 3D modelling program because it is an object with many parts that can be taken apart and put back together easily. I also like the fact that there are no threads and it is all held together by tension. One of the reasons why i chose to do the Minifigure instead of any other Lego object is because of the complexity and mix of shapes all wrapped up into one figure, as well as the endless possibilities for accessories. Still the shapes are basic enough that I feel more confident and not as overwhelmed with the idea of the project. Therefore I believe that object is a good start for me for this project and if I do get through it quicker than expected, then I can always model extra accessories for him and so forth.  As well I have always been a fan of Lego since my early childhood, which makes this project that much more exciting.
