Here we have, for lack of a better implementation, an array

that defines the more intimate aspects of a key.
|
|
||||||
order is thus:
|
|
||||||
1. Bottom Key Width: width of the immediate bottom of the key
|
|
||||||
2. Bottom Key Height: height of the immediate bottom of the key
|
|
||||||
3. Top Key Width Difference: mm to subtract from bottom key width to create top key width
|
|
||||||
4. Top Key Height Difference: mm to subtract from bottom key height to create top key height
|
|
||||||
5. total Depth: how tall the total in the switch is before dishing
|
|
||||||
6. Top Tilt: X rotation of the top. Top and dish obj are rotated
|
|
||||||
7. Top Skew: Y skew of the top of the key relative to the bottom. DCS has some, DSA has none (its centered)
|
|
||||||
8. Dish Type: type of dishing. check out dish function for the options
|
|
||||||
9. Dish Depth: how many mm to cut into the key with
|
|
||||||
10. Dish Radius: radius of dish obj, the Sphere or Cylinder that cuts into the keycap
