I did some comparisons between the Rhino 7 WIP loft subD option and the subD loft command in a plug-in I’ve used for a while. Detailed analysis below, and here’s the file: Lofting.3dm (221.2 KB) 1. Lofting open degree 1 curves. Below are four different results of lofting the same degree 1 curves. …

[image] Max3: I would think a typical user would expect output that looks more like the plugin. I think an interpolate option is what is needed here to get the same border as the plugin… https://mcneel.myjetbrains.com/youtrack/issue/RH-57232 [image] Max3: the option to have “along” segme…

THANKS! re: “along” segments: Tweening doesn’t produce the same result, because Tweened curves either have different numbers of control points than the originals, or rebuilding causes too much deviation. The form is good, the subdivision structure is unusable. Though as glitches go, it’s kinda beau…

Hi @Max3 can you please share with us the name of the plugin?

Clayoo. At this point, I prefer the Rhino WIP’s implementation of SubD to what Clayoo does, and I expect native subD will may to end-of-life for Clayoo. There are still some very useful features that Clayoo’s subD has that the WIP does not (multi-gumball, knife command), and Clayoo’s mesh sculpting…

Should there be ‘Interpolate’ options for these? So that output SubDs actaully match curve input? Can’t tell if that would be helpful or not in the grand scheme of things, for a modelling workflow. [interpolated_loft_maybe]

I think @BrianJ already mentioned “interpolate” in relation to the “underpants” result in item 1 on my list at the top of all of this. Also, it’s been a while since I posted this. In that time, I’ve found a workaround that isn’t ideal, but does allow me to get good results when trying to work with…

Could you post an example? Yeah, I’m still feelign my way through this. I am really the blind leading the enlightened, as far as playing with SubD goes.

Thanks, we’re looking into matching the curves if they are all SubD Friendly curves. I’ve added your comments to the feature request. https://mcneel.myjetbrains.com/youtrack/issue/RH-58592
