Bottle Opener: Version 3
To start I focused on the 3 main circles, putting one on the origin and the two concentric circles at the specified distance. This provided some useful reference points to continue building up the rest of the sketch.
I had some trouble with the bottom right “hook” piece as there were a lot of strange measurements and different constraints that needed to be used. Initially I had tried to use a fillet, but because it was not a 90-degree angle I couldn’t get it to line up. I instead used a circle with tangent and coincident constraints that allowed me to connect it to the bottom and diagonal lines. With this done I was eventually able to finish the sketch.
The extrusion was once again just one step, and with that I had finished the bottle opener. I was initially worried I might have trouble with the hole on the right side, but it automatically excluded it from the extrusion.
Bottle Opener: Version 4
This bottle opener was comparatively much easier. The sketch was just a combination of a few circles and lines, and the extrusion was one step.
Bottle Opener: Version 6
With my first attempt, I gained a general idea of the process to create the bottle opener sketch, but a few miscalculations and incorrect placements meant I had to restart pretty quickly. My biggest error was forgetting to differentiate between measurements of radius and diameter for the fillets and circles.
With my second sketch, I did much better, though I am still not sure if I did the long outer diagonal correctly. Unfortunately, I couldn’t figure out how to center the sketch back at the origin, but other than that it matched all the other measurements.
Extruding the sketch was not too difficult, but I had some trouble figuring out how to extrude the handle and the opening part separately. Additionally, while I got close to perfect, I couldn’t quite figure out how to correctly use the chamfer tool to create the sloping effect of the opener.
Overall I am pretty satisfied with the result, though it may not be 100% accurate in the diagonal and cap opener areas.
