Match Surface problem

[Cayn]

Hello there. I hope somebody could help me. Here's the problem. I want to use MatchSrf on those 2 surfaces between indicated edges but I get different strange results. What shall I do? By the way I use Rhino 4 beta.

Nevermind. I did it. New problem. How i enable Control Points on a polysurface? And how I can copy rows of control points in my object (to make it more detailed)? Hmm... I have a lot more to learn

When you have found out how to do it and answered your own question - post that solution.

If someone is searching the forum and thinks "Yes, that's the exact problem I have" only to find "Never mind, I did it" !!!!

Take a few minutes and explain HOW you "did it".

Ok. Sorry for that. So... let's begin. After I type the command MatchSrf some questions apears:

Select untrimmed surface edge to change: select Edge 1 (edge that will change but it will give an overall shape)
Select edge to match: select Edge 2 (edge that will remain unchanged)

Now in the Match Surface panel use the following options:
Continuity: curvature
Refine match
Isocurve direction adjustment: automatic

here's what i got:

Thanks

That makes it helpful for other members reading who have had the same problem.

i hope no cgcars user will ever be confronted to this problem...cos the solution is awful....you now have a surface with thousands of isoparms....completely useless to work with...and for sure not giving good rendering results....

i say again the philosophy of nurbs is getting surfaces with as less controls point as possible, to control them obviously....

IMO, do the following : build a skin surface between the two edges (that you should rebuild with the same number of cvs first), then increase the number of cv rows in the lenght of the skin surface in order to have at least 6 Cvs (cos for curvature you'll need 3 aligned (or coplanar) row of cvs for both sides) then apply a match modifier (in curvature mode) on both sides....finally adjust the last cv rows if you have some remaining not affected by the matching....

Thank you for replys. I know the surface looks awful. I make something after a tutorial and there aren't to many informations at each step. I just started to learn rhino.. looks interesting but i have a lot of problems and help isn't too advanced. I'll try your solution also even though seems very "alien speaking" to me.
