ok I have a very noob question here.. Ive been using maya for too long and I cant remember how to do it in 3DMax

1: I Have a spline .. lets say its a circle (closed) 4 vertices..

2: what Im trying to do is to split it..add a line ..(create line, poly connect??)

when Im trying .. the vertices ares not connected.. and I cant weld them even at 1000m . its 2 separate spline ..I want them to be the same.. connected AND weld

how?

:rolleyes:

hello.

:)

use 'refine connect' to splite and connect.

and about welding...
in my opinion, it's kinda pointless to weld verticies in most of times.

however, if you want to do that,
use 'fuse' to place vertices on the exactly same spot.
and then try 'weld'

I love spline modeling. :applause:

ok my girlF was doiing this tutorial ..

flower tutorial (http://www.3dcafe.com/asp/tutorials/max/patchflower/patchflower.asp)

and she was asking me..why when (in #2) she add the cross section ..she cant weld the vertices..
no mather what I tried , there is no way to have the cross-section vertices weld on the original leaf spline .. ???

thanks for your help neversong

BTW fuse work well thank but when I tried to weld then after..its still saids ..No vertices within weld threshold ... and I put it at 9999.99meter

Welding is only for end anchors on a spline.
You can't really weld anchors in the middle of a spline.
That's what Fuse is for.

Kind of a shift in terminology and how things work.
Took me awhile to figure it out.

oh well... thanks Stroker

no problem, kheemo.

just like Stroker said, not all vertices can be welded...
I noticed.

spline modeling is worthless

No it's not.

Anyway, check out the "Area Select" feature near the top of the Edit Spline rollouts, it's a tiny function that makes selecting these stacking CVs much easier. It's default value is usually quite nice for making sure you're selecting all the required CVs, instead of just the top one. Which get's annoying real fast.

And as already stated, there's no reason to weld CVs, each CV represents a knot on a single spline: one edge going in and one edge going out of the CV. Thus two CVs are needed when you have a spline intersection. Welding is a poly-habbit, not worth tumbling with in this genre of modeling. Hooray.
