I’m really looking forward to this command, now that explicit cv control is available in the rebuild command / raise degree. Working with single span Bézier surfaces and realigning them when some adjustments need to be done on models coming from another software is critical. This will take plasticity into the automotive / transport design fields. You will see studios adopting plasticity after this update, and I’ll be the first promoting it! Nick you are the man!

With this feature also an isoparameter visualisation option should be added. 1 ISO Curve un U and 1 in V direction. (Or optionally settable number of ISO Curves.) Also a local Gizmo on the Surface showing U,V and N directions will be helpful. A curveture Comb Analysis and Connect Checker function is a must for creating higher quality surfaces. Every option to achieve higher quality surfaces without analysis is not applicable in real modelling situation.

very important!!!!!! and if you would have the option to manually set the degree/isoparms which are used try to achieve the wanted continuity you really could be able to produce class a single span models. This would allow much more control than the rhino match surface tool. if the tool shows in what tolerances the continuity is archived you can decide by yourself how "heavy" surfaces you except and what continuity is enough for your purpose. an good example is the alias align tool with the possibility for explicit control.

This would be for me the absolute game changing tool.

Absolutely phenomenally important! I think it can take Plasticity to the next level it deserves as a surface modeler. As of right now there is no way to avoid secondary surfaces being overly multi spanned and complex.....Cant wait to see the result Nick....Im also working on car like surfaces

From all the feature requests I believe match surface and curvature analysis are the most important to build high-quality surfaces. And as Michał Męzik said we need a tool like VSR. These will make plasticity one of the best surface modelling programs.

Here is a good video on Match Surface: https://www.youtube.com/watch?v=oVauNTedU-M&ab_channel=thirtysixverts

Yeah! It's a pretty necessary thing. I use this all the time in reno. This is not the case in plasticity, which makes the modeling process difficult. Instead of making a match of curves, you need to delete old curves and create new ones. There are many such moments.

We need a tool like VSR for Rhino

Yes, this would be very useful since it allows the start simple and add complexity as you need it approach. You could start with a simple line to connect things and depending on your model you would either match or trim back the sharp edges and fillet/blend in between.
