Radial size
The radial size is defined as the diameter or mounting position for most parts. If the mounting position is not radially the part is either round or one of two special forms. Rectangular parts like the M-1x1 Structural Panel don't have a radial size or its a size to the next bigger diameter like the Probodobodyne QBE. There are three radial sizes existing with varying names. The size scale looks like the internal definition as the Mk2 to size 1 Adapter uses this term and starts with 0 and many values in computer programming are starting from 0 rather than 1.
| Name | Size scale | Meter scale | Actual size | Example |
|---|---|---|---|---|
| Tiny | 0 | 0.5 m | .625 m | Clamp-O-Tron Jr. |
| Small | 1 | 1 m | 1.25 m | LV-T30 Liquid Fuel Engine |
| Large | 2 | 2 m | 2.5 m | Rockomax "Mainsail" Liquid Engine |
As a special radial size Radial mounted appears. Parts like Rockomax 24-77 don't have any general metric counterparts so there is no confusion about them.
Additionally there are two non cylindrical sizes named “Mk2” and “Mk3”.
