Rhino WIP has a completely revamped Patch command. [Patch-FillSrf | New in Rhino WIP] What is Patch? Patch takes a set surface edges, curves and points as input constraints to create a multi-sided patch with positional (G0), tangential (G1) or curvature (G2) continuity to selected edge…

I’ve noticed that Refine significantly slows down the Patch command. In some cases it even fails, whereas when I disable Refine, the patch is created much faster and the isocurves are also easier to control and adjust. Global Edge Continuity Rhino 9 WIP test [Global Edge Continuity Rhino …

As you can see in your screen recording, history turns off once you started the command, and is off when you click OK. As said, this needs to be fixed, but I …
