Upright Drawing
important features/interfaces | constrained w/ | why | |
|---|---|---|---|
| 1 | Axle | Datum A, flatness | Datum A b/c we wanted a surface to use for (2). Although only the middle touches, more reasonable to constrain that whole side. |
| 2 | Axle | Parallel | Actually unsure why we parallel’ed the top feature.. but the bottom one for axle fit. |
| 3 | Axle | Datum B, Perpendicular | Creates another datum on a diff plane than Datum A, further restricting degrees of freedom. Also very important for axle fit. |
| 4 | Rotor | Parallel w/ Continuous Feature | Looking back, the 2X was redundant when used w/ the CF. Either should have worked. |
| 5 | Bolt (thru brake caliper, upright, rotor) | Datum C, Position | Needed a final datum, and useful for constraining second hole. Pretty average callout. |
| 6 | Bolt (thru brake caliper, upright, rotor) | Position | The traditional dimensions probably could’ve gone on either but moved here for readability. |
steering arm mount holes??? idk the callout format
