Auto update sections in Rhino

Is there a way of making it so that section lines - sections, buttocks, etc - will automatically update as you alter their parent surface in Rhino?

I'm affraid Rhino is not a parametric software, like Solidworks or UGS NX. However, it has the "Record history" option, which might help you. See this video here: http://designreform.net/2008/05/rhin...-along-surface It has also taught me the usage of "Flow along surface" tool, very handy for some tasks.

Cheers

It looks like Grasshopper plugin gives the possibility of parametric modelling to Rhino too: http://www.grasshopper3d.com/
Think I'll give it a try.
Cheers!

Another possibility (which I haven't tried) would be a simple script to create the lines, and then run the script when ever you wish to update the lines. Put the lines on a separate set of layers, have the script delete them, then run Contour to create a new set of lines.

Will the method that I outlines in Yacht design in Rhinoceros 4 post 33 can also be used in a static form. By putting in a series of planes for sections, waterlines, etc. do the history/ intersection for each, then put the planes on a separate layer so you can turn them off, leaving the intersection line which will move with the surface. You can also put the lines on their own layers so you can turn them on and off.

Thanks for the reminder.

There is another method where you can use the ôsymmetry command to mirror the half hull being used to edit. If you then put a plane like the others through this, to get say waterlines, then hide the plane and the new hull side on layers, you then can have sections on one side and waterlines on the other all up dating when you move the control points on the original hull. There is one small limitation to this after symmetry on the original , the first control point after the centre line tends to want to have a tangent type relationship with its opposite which limits what you can do with it. I found if I snapped these control points to their centreline point, making them redundant , then add another row control points after them gives you back control.

Hi,

you could have a look on RhinoParametrics plugin for Rhino 4 which gives you the same range of functions as classical parametric cad software.

Rhino Marine does it. Costs a few dollars but worth it.
