How to cap 2 nurbs curves?

[Travis.Designer]

Hi

I intent to use Push/Pull tool to make solid

I try drawing 2 lines to cap then Compose 4 object but it's not work. Need advice.

 

Thank

Travis

Did you convert the lines to NURBS Curves before you tried to compose them?

Previously, I select 2 lines then Convert to NURBS, they will be Group. This time, I select each line, convert to NURBS. then select 4 nurbs Compose. It work good. However when I Push. It become like picture below:

What happen? It's not solid (changed to OpenGL view)

Loft the curves into a surface and then run a shell on the surface to create a proper solid shape.

Hi Claes,

It work in case because I have 2 similar nurbs curves. What if we have 2 different of nurbs curves?

You can loft two NURBS curves with  different shapes. Loft simply means that you connect two (or more) curves into a surface.

You can only combine NURBS with other NURBS. So you correctly realized that you have to convert the lines to NURBS so you can Compose them. You could also select the 4 curves and Create Surface From Curves in the 3D PowerPack to get a single surface that you can then use the Push/Pull Tool on.
