Large Loft Issues.

I have a large area mesh with high fidelity that I would like to turn into a surface. I had expected that by using the contour tool I could get serial section cuts of the whole surface and then loft these curves to recreate the mesh as a surface.

The issue is that when I attempt the loft I run out of memory. I am running a powerful computer with 32gb of ram, ssd, 4gb gpu, So I don't feel like it is an issue with hardware but more an issue with the nature of the operation.

Does any one have insight into why it is not possible to use loft, and is there another series of operations that might work.

would trying to use multi-threading through Python make a difference? I'm naive here but I feel like there is a solution other then needing endless ram.

thanks

Sections through a mesh will get you polylines. If this mesh is large and fine, those polylines will consist of a lot of short segments. Lofting polylines typically will create separate surfaces per segment. That's likely to blow up memory consumption.

Before you create the loft, you should rebuild the polylines to NURBS curves with a sensibly low amount of control points. Then loft those rebuilt curves.

Thanks,

when I use the "fit curve (fit)" component it says that "polylines" have been converted to "curves" - Im assuming this means they've been Nurbed. I'll see how this goes.
