100 Days of Onshape

About: 100 Days of Onshape is a collection of youtube videos created and posted by LearnItDoItMakeIt. In these videos, the CAD program "Onshape" is explained and taught. The first video starts by explaining the basic tools in the part studio, including sketch and extrude. Slowly throughout these videos, almost all tools, buttons, and features of Onshape are explained thoroughly. There are currently 64 videos in the playlist and they are more in the process of being made.
How We Use It: Newer members of Code Sisters are introduced to all parts of the team. They get experience in building, coding, and CAD. This allows members to find their passion. Code Sisters uses the first few videos to introduce these new members to the tools in Onshape, the CAD system we use. For those that decide CAD is for them, the rest of the videos explain some of the more complex features in detail. ​

​Progression of Team Shipping Element

This year, Code Sisters went with a cone design, to avoid a similar appearance to freight. We also added customization in the form of ‘Code Sisters’ written in different ways. For more detail, see Engineering Notebook Entries.
VI.I
Pros: Usable size
Cons: Unable to wrap text on cone and too basic 
VI.2
Design: Added code sisters on the flat section (both normal and morse code version). This took a lot of calculations.
Specs: Angle of Cone - 25.313 deg.
            Height in total - 70 mm.
            Height of first angled section - 20 mm.
​            Height on flat section - 16 mm.
            Height of second angled section - 54 mm.
            Diameter of base - 75 mm.
            Diameter of top - 5 mm.
V2.I

Rocket ship design.
V3.1 - Formally Known as VI.3
VI.2 with modifications, such as shorter design and larger base (to increase stability). 

Progression of: The CHASSIS 

Goal: CAD Strafer Chassis
Process: 
  • Download parts from Onshape FTC Parts Library
  • Find instructions online 
  • Build the chassis 
Issues: Discovered after the fact, there are two different strafer chassises, under the same name. I built the wrong one.
Moving Forward: Find the right strafer chassis in Onshape.
Goal: CAD the Correct Strafer Chassis
Process: 
  • Find the correct strafer chassis - preferably pre-build in CAD
  • Unzip the file
  • Research how to convert .STEP into Onshape (Without Errors)
  • Fix the Errors
  • Move the Chassis into the main document
Issues: One of the U-channels is blue
Moving Forward: CAD the rest of Vector

Progression of: Custom brackets

​Goal: Create A L-Bracket that has Servocity Pattern on one Side and Pitsco Pattern of the Other 
Process: 
  • Download both original L-brackets 
  • Use the remove function of the extend tool to cut off the unneeded sides
  • Combine the sides in the correct place
  • Convert the custom bracket into a file useable by the 3D-printer
Issues: No large issues, only small errors, that were quickly corrected 
Moving Forward: Print the Bracket

progression of: rack and pinion 

Goal: CAD the Rack & Connecting Parts
Process: 
  • Download parts 
  • Find exact holes used to connect on real-life Vector
  • Connect using fasten tool
Issues: The rack part was not on Onshape - Downloaded from website​
​Goal: CAD the pinion, pinion motor, & servo for Collection Box
Process: 
  • Find names of specific parts
  • Download parts 
  • Fasten main section together
  • Figure out how to CAD on an axle
  • Add part to axle
  • Put axle on the main document
Issues: Had to download bushings & gear from outside source
Moving Forward: CAD the servo

progression of: Collection box

Goal: CAD the Design of the Collection Box
Process: 
  • Take measurements of the box
  • CAD box in Part Studio
Issues: The real life version is flexible - the Onshape version is not
Moving Forward: Put the collection box on Vector

progression of: sweeper 

Goals: CAD the intake sweeper
Process: 
  • Download the parts 
  • Cut the x-rod to exact measurements in a separate document
  • Find the exact holes used by the builders 
  • Put mate-connectors on the place where the holes were drilled for screws on the real robot
  • Attach the parts of the sweeper
  • CAD the motor 
Issues: 
  • The flat bracket used by the builders is not on Onshape, and they don’t know where it is from. 
    • No substitute has been found that fits what we need it to 
  • The builders drilled somewhat  random holes in the x-rod for screws. Onshape needs specifics 
Moving Forward: Find the correct Flat Bracket

progression of: duck sweeper

Goals: CAD the Duck Spinner
Process: 
  • Download all part necessary 
  • Locate design of specific pattern converter
  • Build the Duck Spinner
Issues: 
  • Can not CAD rubber bands
  • Stand rods and diagonal  
Moving Forward: Address the issues
