Connecting spline for roof doesnt work

[Anonymous]

Hello everyone, i already searched for a similiar problem, but I did not find any.. I'm new to 3ds Max and im using 2014.

I created a spline from a shape, which is the upper spline. The lower spline is created by the  create line option. With refine i added a few vertexes.

Now i want to connect the vertexes but it doesnt work. The only 2 vertexes that are connectable when i click on connect (a little + appears when I hover those vertexes) is the lower right and the lower left. When I use cross section, all the vertexes connect anyhow, but not the way I want it. Can anybody help me?

Hi. A spline vertex can't be shared with more than 2 line segments. I'm not totally sure what you're trying to achieve, but one way to do what I think you're trying, is to need to make 2 closed shapes.

Hope it helps, otherwise provide some more information about what you want to do.

PROH is correct - you cannot weld vertices where the result would have more than 2 Segments attached to the Vertex.
For a simple shape like that it would be much easier to Box model it than to use Splines - is there a particular reason for using splines?

I wonder why the limitation?

[Steve_Curley]

No idea, but that has always been the case. Splines simply cannot have "T" or "Y" (or worse) junctions. 1 vertex, 2 connected segments. That's it.
If it is intended that a Surface Modifier is to be used then it's not a problem - Fuse the vertices where lines cross and you'll be fine. Remember "Modelling a Knight" from the chess set tutorials?

Ha...ya I do remember that tut. I also remember I never completed it. Hmmmm.

😄
But you likely remember the basics anyway (hopefully).

I do. I also know the "rules of the spline". I was just wondering if there was some good reason behind the rule.

Thanks for your replies.

Sadly not, no clue here. Except that if you could connect multiple segments to a Vertex then you'd have a Wireframe model - an Editable Poly without the polys...

Thank you very much! I did it with shaping a cube, too bad it didn't work that way.. I have an other issue, does anybody know why 3ds Max shows all the "hair" in the viewport? In every tutorial i watched you only can see a few hairs, but i tried to put some grass on a plane and it is immediately full of it without rendering. Somebody knows why and how to change it? Because the viewport starts to judder when i try applying hair..
