Spent some time this afternoon filling out the slide deck for the final project in the robotics course. Nothing too exciting, just documentation for the programs we created earlier in the project. With that submitted, my semester is done, and I’ve got a couple weeks to work on personal projects before the Summer semester starts.
It is funny how much more work it was to generate a 2D Isometric drawing for this assembly in AutoCAD than it was to create a 3D model of each part in OnShape, print them all, and assemble. Some things that are trivial tasks in modern software, like drawing a circumscribed 7/16″ hexagon for the bolt head, were extremely tedious to draw on an isoplane in AutoCAD. I wasted a couple hours last night trying to find a documented method,…
I decided to spend my lunch break today working on AutoCAD, figuring I could knock out one or two modules and be better placed to finish the book over the weekend. Completed modules 35 and 36, finishing Part 7 of the book, then found Part 8 is just the book’s index & revision history tables, so I’m done with all of the reading and lab exercises, just need to finish the final project. These exercises seemed very easy, like they…
Since I still don’t know how to generate the bill of materials from block attributes in AutoCAD, and that isn’t covered in the book I have, I went ahead and modeled the part in OnShape for 3D printing. The hardest part was figuring out how to model knurling on a part surface. Normally I wouldn’t waste my time modeling or printing standard parts like nuts and bolts, I just didn’t have any 1/4″-20×3″ bolts on hand. If Tuesday’s lecture doesn’t…
