A KSP editor mod that keeps the dimensions of connected parts in step.
Change a procedural part's diameter and the new size travels up and down the stack, stopping at the first part whose facing end was a different size than the changed part was before the change. Change a procedural wing's tip chord and the next segment outboard takes it as its root chord. Stock parts, radially attached parts and anything the player cannot edit are left alone.
Hollow parts are understood: a bore and an outside diameter can follow one another, a stack can be matched to either, and a part slid inside another's bore keeps its clearance when either of them is resized.
Out of the box it knows about ProceduralParts, ROLib (RO-Tanks and friends), Procedural Fairings, SSTU and B9 Procedural Wings; anything else can be added from config.
