Assignment 3: Technical Diagram Drawings

 This project started out as somewhat bizarre and frustrating for me. It remained somewhat frustrating throughout, but there's a sense of accomplishment as I managed to do math (!) and experiment with the tools I had more to create an at least moderately satisfactory result. I completed 3/6 of the diagrams.


Perhaps later, I'll add the results of diagram #6 to this, though it's a little confusing as I wasn't sure whether the diagram notation was the radius, or was just an odd 0 and meant to indicate the borings should be 0.5 mm through the object itself (it should be the diameter, because eyeballing a 5mm radius makes the circle too large for the object). I also wasn't sure how to achieve the results of customizing the curves to have those gear teeth on the third step without it being messy and hacky.

All the same, I learned in this assignment how to better use Sweep1 and Sweep2. This turned out mostly well, except for the part where it was difficult to fillet the curves of polysurfaces after creating them, and I'm still not sure how to do it.

For pretty much all the objects, I just duplicated the 2D diagram of curves that I made and lifted them above the original curve to Sweep1 them together into a thin shape. From there I'd use Cap to make them into a closed polysurface, which worked more often than not. For complex surfaces, I'd just cap the inner shape of a surface and use Boolean Difference to subtract the shape.

I think the object that gave me the biggest breakthrough was #4. I had to make a lot of markings and use some math to figure out how to make an arc that could be duplicated and rotated along the gear's axis, but it turned out overall the best of my shapes. This is also where I made the most use of Sweep1, but I used Boolean Union and difference to combine the raised inside of the gear and subtract 1mm of it. 

I might come back to this one day for more practice, but I'm just happy to report that I made some progress in understanding Rhino's more complex tools.

Assignment 5 Part 3: Reverse Engineered Object

 So, it is finally done.   Rhino's rendering capabilities are not as powerful as Keyshot's, admittedly, but lacking a Keyshot license, I am pretty happy with how these turned out. It ended up being enjoyable to render these parts, and I learned a fair bit about measuring, more about the tools I could use in Rhino, and how to effectively colour objects in Rhino (you have to have those thumbnail objects on the Materials window open to get the effects to apply correctly). I still wish I was able to add the detailings present on the original pen, but it would have been a very long and arduous process learning how to import Grasshopper curve maps on to a surface in Rhino, and even longer learning how to use Grasshopper to create these very detailed shapes. Knowing they exist, however, is half the battle. I also wish I'd used my time more effectively to figure out how I could use a tool like Taper, or create a better shortcut to having a straight slope of a tapered object, but t...

Assignment 1: Castle

  I wanted to do something that was a little unconventional and took inspiration from architecture outside of Europe. My first thought was the Taj Mahal for "famous palaces", but I thought; why not extend the definition a little and make a building inspired by a mosque? I took inspiration specifically from mosques in Iran for this project, as shown here:     I started out with a basic layout and floor plan, as well as some sketches. I moved into the modelling stage with an idea of an inner courtyard, with some small minarets and domes. The second image shows how I started; with some 2D shapes on a flat plane to map 3D shapes on later.     When I finished, I decided to keep the colours and stylings relatively minimalistic, though I might have put more decorations on the corners of the roofs and windows. I wouldn't know how to do that without vastly overcomplicating the project, but it's something worth looking into.
