To ensure consistency across mechanical team projects, please read over this page and follow the practices when you are working with the mechanical team!
1. Coordinate Convention
FOR HIGH-LEVEL ASSEMBLIES OR PARTS DIRECTLY RELATED TO LOCATIONS IN THE OCCUPANT SPACE:
USE THE DEFAULT SOLIDWORKS COORDINATE CONVENTION
THE ORIGIN IS PLACED ON THE FLOOR WHERE THE CENTER AXIS INTERSECTS THE FRONT PLANE OF THE CAR
...
| title | What counts as a high level assembly? |
|---|
A high-level assembly means that the assembly’s position ultimately determines the position of many related subsystems of the car.
...
The origin of the car is placed on the floor where the centre axis intersects the absolute front of the car
Use the Default Solidworks Coordinate Conventions
...
This means
Origin on the floor, intersecting the centre axis at the front plane of the vehicle (circled below in the occupant space definition diagram)
positive z-axis pointing to the front of the car
positive y-axis pointing to the top of the car
positive x-axis pointing to the left of the car
...
Please abide by the mentioned coordinate system for assemblyor parts that use the entire vehicle as a datum (the position is directly related to the origin mentioned above)

A high-level assembly is an assembly that completes a subsystem of the car. The high-level assembly’s position ultimately dictates the location of many parts in the car. |
Of course, for parts that are not directly related to positions inside the occupant space - the origin does not have to be positioned as mentioned above.

If you are unsure/need clarification - ask a lead to confirm!
If your design is symmetric on both halves of the car - design on the “left” side of the car (where x is positive). Keeping more things consistent across teams is always beneficial.
...
Using hole wizard is an efficient way to place holes in your parts while making sure that hole sizes remain consistent across the whole team.
