We came across this a couple of times also in older posts, but those were primarily focused on getting the shape rendered. Now we are back in using the hose a bit more, and needing different shapes, but keep running into the fact that is extremely heavy. I uploaded the file so those who might have any ideas could take a look, both the two curves used to make it and the results I’ve gotten are in there. http://speedy.sh/UhcvV/Hose-Problem.rar I hope anyone has got a good idea how to get a shape as this running better. Or know a way to prevent sweep1 of making so many subdivisions/edges/isoparms using these curves. I tried rebuilding the helix, but that makes the helix non-round.

Hi Peter, First to preserve data I would not model the material thickness, but just the outer sheet. Second I would create a mesh instead of NURBS, the advantage is that flow will not increase the density and the looks will remain. What I`d do is build a basic hose turn from polyline sections. That will create a faceted polysurface that can be cleanly meshed. Once you have a faceted mesh, you can weld the mesh to get a smooth appearance.

Losing the material thickness is a possibility I could apply, though the Mesh option seems to give a too blocky result in the amound of divisions you have used, using more divisions would then again make the mesh heavier. It is going to be used in both scenes, and close-up renders so it has to be very round. In your given example this is not yet the case, would you imagine in using a higher density mesh, it would still be lighter then a nurbs approach?

[image] Peter: would you imagine in using a higher density mesh, it would still be lighter then a nurbs approach? Yes, I think so, but you will need to test that. Also note that for closeups you can always use more dense geometry, but maybe just the portion visible. For wider shots you can use the less dense option for faster rendering. -Willem

I’m trying some things out now concerning 1 sided and mesh options, though if anyone has any other tips on this problem they are most welcome. Nurbs is the easiest way to build this, but has been just so heavy

Have you tried creating one turn (or a few) as a block, then using as many instances as required to create the whole length? I had a similar issue some time ago trying to model a solenoid of wire and one of the NcNeel guys (I don’t remember who) made this suggestion and it helped quite a bit.

@pascal Would you know anyone in McNeel that might have some info in how to build such an object so that it is not as heavy? The file contains the steps I used to create the shape as it is now.

Peter, is there any way to download this without installing junk on my machine? Can you use http://www.rhino3d.com/upload to get it to us? Thanks, -Pascal

Hi Pascal, You clicked the “wrong” download link… see where to click for direct download of the rar: [image] HTH -Willem

The problem is that it is a spiral shape, so if I would make blocks out of it, it would be impossible to bend it without getting gaps/overlaps afaik.
