Note that I've specified radius here such that it is divided by size to get the actual model radii, with the model standardised at unit size and then scaled – which is what happens with every other mesh model. I feel that specifying the standardised radii would be really confusing for the user, e.g.:

!rbox size=100;100;50 radius=0.1;0.1;0

This would intuitively look like a tiny corner radius instead of the 10 unit radius it actually works out to be once the model is scaled, and even harder to make sense of if the side lengths don't match but a single radius is desired around the edges/corners.

Scaling the underlying models means that they can be more easily shared, since:

!rbox size=100
!rbox size=1000

can both use the same underlying model – though, arguably, this is rarely going to happen.

It also occurs to me now that:

@rbox size=2;1;1 radius=0.5

is a capsule!
