To ensure consistency across mechanical team projects, please read over this page and follow the practices when you are using Solidworksworking with the mechanical team!

1. Coordinate Convention

  • planes and where the origin will be placed

  • When symmetric, sketch on which half of the car

FOR HIGH-LEVEL ASSEMBLIES OR PARTS DIRECTLY RELATED TO LOCATIONS IN THE OCCUPANT SPACE:

  • USE THE DEFAULT SOLIDWORKS COORDINATE CONVENTION

  • THE ORIGIN PLACED ON THE FLOOR WHERE THE CENTER AXIS INTERSECTS THE FRONT PLANE OF THE CAR

titleWhat 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.

  • ex. The chassis of the car: the wheel positions, canopy and many other things of the car depend on the exact position of the chassis

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

...

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.

  • ex. The steering wheel does not have to follow the origin since it is not directly related to the position in the car

    • It is related to the position of the stalk → the rack and pinion → the overall dynamics high-level assembly (which is eventually related to the position in the car)

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.

2. Design Units

  • Design the car in metric, the only exception being critical fasteners in imperial. Normal fasteners can be metric or imperial, but consult your team lead and keep it consistent.

...

Critical Fasteners: Fasteners for critical areas, which is defined to include: steering, braking, suspension, seat mounts, safety harness, drive train, battery box, ballast carrier, and parking brake.

3. Hole Wizard

  • Use Hole Wizard when placing holes in your components.

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.

Templates

  • All mechanical components (ex. fasteners, nuts, washers) models should be taken from McMaster-Carr, NOT the Solidworks design library.

When using off-the-shelf (OTS) mechanical components, these are usually purchased through McMaster-Carr Website: https://www.mcmaster.com/

Check the Bild PDM if the component is in our

design library and import the model into your assembly.

If the model is not available, download the CAD from the McMaster-Carr website, and add the part in our bild PDM in the appropriate directory under a consistent naming convention.

titleDownloading parts from McMaster-Carr

MMC basically has all the mechanical components you need for your design - once you find the appropriate component, click on the part number, and select 3-D Solidworks to download the CAD file for your component.

Bild PDM Resources

  • Review the link above on how to use Bild as our PDM system to store all our CAD

All MS16 CAD should be stored in the Bild PDM to be accessible to everyone on the team and for version control.
