Hi! Any shipdesigners here who use Rhino for the shell expansion?
We have a tool in grasshopper that uses intersections in one direction and create new interpolated lines, but lines with arc’s (like the windows) doesn’t work unless the intersection resolution is set very high.
So the question is: is there an automated way to unroll all markings on a surface in only one direction (Y-axis in this case)?
For non-shipdesigners, it’s the shell of the ship with the construction markings → unrolled in the Y-axis (the axis perpendicular to the length of the ship)
I have done these in the past in ShipConstructor; I think if I was going to automate it in Rhino, it would be something like:
-project curves to the XZ plane (assuming Z is vertical)
-make a surface on the XY plane which has width equal to girths sampled along the hull
-flow the projected curves along the “girth” surface
Has anyone had any luck doing the reverse? APPLYING a shell expansion plan to a hull form? I’ve been fooling around with Flow/FlowAlongSurf etc but can’t get anything to work.
I’m trying to apply the Shell Expansion plan of the Normandie to a hull I’ve modelled.
