Ok, first some praise: Despite this thread, the QuadRemesh command saved me a lot of time in this instance, and I was very happy to see a “modern” dialog box for the tool, even with some basic built-in analytics!
(Imagine if every other tool in Rhino could be upgraded to this UX standard… we’d almost be entering the 21st century with the app instead of being stuck in the 90s… sorry, I couldn’t help myself, and yes, I know the Mac version already has this pretty much everywhere since many years back).
I noticed that even on what I considered to be a very simple shape, the tool generated overlapping quads:
Thank you for the screenshots! Interesting, I never though to just use the min and max edge lengths.
Hmm… I seem to be getting a very different result from you, though. In Rhino 7.27 using your settings, I don’t get a result at all. In fact, 8-5 doesn’t give me a result at all. At an edge length of 4, I get a result, but it is not as nice as your screenshots:
I might be missing something obvious, since this is pretty new to me. However, apart from that, one further important difference is that you don’t use the “strict” setting for surface edges, which was important in this case.
Your settings are different than mine if you compare images.
You shouldn’t need any guide curve input here such as surface edges. Strict only means to use every brep edge no matter how small. You should pick Smart in the majority of cases should you decide to use it.
Looks like I changed it internally to use the high quality render mesh or the objects custom render mesh settings vs the document settings.
So…If you aren’t getting a result, then run ExtractRenderMesh and run it on that.
As for the curve input, again in this case, I really wanted strict, and apart from the red markings I made in my first screenshot, I thought it worked pretty well. (I also noticed that when I switched to just one or two guide curves, the remesher might still decide to ignore part of the curve, and I’d have hoped it would move the “inaccurate” areas to somewhere else.)
