CAD design method
This will be presented using a lecture format
The goal of this presentation is to develop consistency in design across the board and ensure that people are implementing best practices while doing CAD
How do we want to approach reference dependencies - do we want to design in context of assemblies
Highlights
Does anybody have any highlights from the week they would like to share?

Blockers
It was brought to my attention that some people are having a difficult time knowing where/how to start since some design/architecture decisions haven’t been made yet. What are y’all having trouble with?
We should implement the philosophy that designs can be started even without defined constraints. This involves incorporating enough flexibility in your design so that you can modify it once these constraints have been set.
Finalized hardpoint locations (we can work with a general idea for now) but like also this isn’t exactly ideal
Finalized hardpoint locations (we can work with a general idea for now)
Front or rear biased (generally battery box and driver locations)
Driver measurements
Workday Review
Suspension:
Further progress on new member task of creating their own suspension
Steering:
Looked into upper steering column and its relation to lower steering column geometry
Unsprung:
Each member researched further and is starting to develop calcs for their section of research, started CADing practice unsprung parts.
Frame:
Talked with suspension for clarification on what rear trailing arm and double wishbone approaches look like for frame
Also got together an approach for designing around hardpoints and making reference sketches
Driver Model outline is finished; will only change slightly based on ergo jig collected data/survey data
Ergo and pedal jig plans are finalized; just needs to be reviewed before being manufactured
Next Workday Plan
General:
Go over the reference sketch and get the HDPT-DYN-24 sketch to be a thing
Suspension:
Check up on member progress on their suspension designs hopefully they are close to being done or are done
Steering:
Talk to Jacob about lower steering column and geometry
Unsprung:
Practice CADs for their parts (uprights for Sumi and stuff) should be a thing and can be reviewed. Continue practicing through more designs and getting a feel for unsprung and its relations
Frame:
Go over general statics/solids intuition as applied to frame building
Continue determining general roll cage dimensions and creating frame reference sketch
Create varying designs for front and rear of chassis (new member task)
Ergo:
Review and then manufacture the pedal jig → Finish measuring drivers
Continue adapting percy model with survey data and eventually measured data
Generate a preliminary steering wheel design/manufacturing method
Continue brake calcs
Daybreak Progress?
New Suspension Geometry - due Yesterday
New Wishbone Model - due Yesterday
Select Spherical Bearings - due two days ago
Bearing Mounting Scheme - due Yesterday
Bearing Mounting Design - due Yesterday
Progress on Refinishing bottom shell?
Shell to frame ideas?
Pedal Box redesigning has progressed → Pedal Jig can be manufactured after review and new pedal/master cylinder location can be tested and verified
