tsplines and Grasshopper smoothness problem.

Hi, I don't know whether this is a tsplines problem or a Grasshopper issue - or probably me... I bring a tsplines surface into grasshopper and try to array it along a curve, in this case. The tsplines is smooth but grasshopper looks at as a mesh. When I bake it, the resulting nurbs surface is jagged, no matter how much I subdivide the original tsplines surface. How can I maintain the smoothness of the original tsplines? Thanks.

The definition is pretty minimal BTW.

Sending a GH file without the corresponding Rhino file doesn't help very much...

Anyway, since you obviously didn't use any specific TS-Geometry related component, I guess the problem is as follows:

GH doesn't know T-Splines. However every T-Spline object needs to have some geometry representation, that rhino understands. That's, what GH can load as a geometry.

I'm guessing at the internals here, so I might be totally wrong. Your "jagged" result is probably what you would see if you toggle off the T-Splines Smooth mode. This should be the base geometry, that resides in Rhino and where TS works it's magic on.

If you download the TS GH addon, you should be able to run those jagged objects throught the TSConvert component. Or you should be able to bake and select the jagged objects and use the Rhino version of tsconvert to make them smooth.

Thanks!

I guess my problem was that the tsplines object is being treated as a regular mesh. If I bake and then convert the resulting mesh into a tspline - then smooth - then convert to nurbs it looks fine. Apparently though, not the way to go about it. I'll download the addon.
