These are hull curves from a ship. I'm trying to figure out why I'm getting this kink between these two curves. I was thinking the surface would simply connect from one curve to the next. Are curves that quickly turn and change direction too complex for Network Surfacing? Any suggestions from others who solved a similar issues that can share their approach - thank you. I have found that I could split these curves in half and create a new connecting curve where the surface is pulling away, although that seems to be a tedious work around.

 

Appreciate any suggestions.

I think that without having the actual curves at hand it will be difficult to diagnose this problem.  Can you post the file?

Hi Shubin,

Creating ship hull surfaces with _NetworkSrf command leads to nothing.

Please read this article and download the example file: http://rhinocentre.blogspot.nl/2009/11/rhino-rapid-hull-modeling-me...

When reverse engineering an existing hull I only use the original curves as a reference for a clean new hull.

Best,

Thanks Chris.

You're right, but I can't post this file (my apology). I was thinking or hoping someone knew a cause for this that had a common fix.

Rebuilding the curves using non-uniform curves gave fewer control points which led to better results. Prior to this I was using the standard Rebuild command. These curves were not drawn by hand.

Gerard,

The difficulty here is that we are not creating a clean new hull from original curves. This model is to reflect the surface that currently is, meaning the as-built (surface flaws, dents, etc). I watched all of your videos many months ago. I like your style and try to adopt the same approach when I feel it suits the task. Network surfacing (until yesterday) has always given me close to excellent results (for the work we do), although I'm always open to learn and improve. Thank you for taking the time to respond. I wish you had more videos :) They are a pleasure to watch and learn from.

Hi Shubin,

That makes sense. I was not aware that you have to reverse engineer. From what I can see on your screenshot, the control point distribution or knot distribution causes the kink. Rebuilding or fitting the curves might be a solution.
