Hi Curious, re:

> Her for example I selected the 2 blue curves and just hit loft, the resulting geometry is super dense!

Even with the new file I can't seem to reproduce this screenshot above, I don't see the upper curve. I've got these ones:



But the one in your screenshot seems to have points here for example which I can't find:



Over here lofting the curves from those files doesn't make a dense surface:



But if they get rebuilt then they seem unusually dense. I don't really see anything wrong with them so I'm not sure why yet, I'll investigate it some more tomorrow after the new v4 beta release. The current v4 beta is going to expire in just a couple of days so I've got to get a new one put out today.
