Question about modelling with NURBS surfaces.

I wish to remain in curve mode for my purposes here.

-If I have the edges and two vertices from two separate NURBS surfaces touching each other, how may I join the four separate vertices to two? May I join the two separate touching NURBS edges to form one?

-I know how to do surface folding, via a common edge, in mesh mode, by changing the cursor position and the handle position. Can I do NURBS surface folding in curve mode in the same way, after joining? I know that I can achieve it before joining.

-I am trying to do object hierarchy by using <ctrl> + <p> and <alt> + <p>. I know that that the empty object that you set is just an empty 3D axis object (at least so I think).

-I can get a NURBS surface object that I have parented to the Plain axes to be show as a child object on the object hierarchy view. What’s wrong here?

However even though I select the [keep transform] object, the sub-object is changed.

-How do I enable parenting without the child object moving at all?

-Even maybe in a way that Java3D will recognise via it’s main tree Node classes, Shape3D, Group, SharedGroup or TransformGroup? Does anyone know that if Java is set up to load from a recognised format, it will put hierarchy objects into these classes as groups by default?

Nurbs are vey simple in Bl!

but don’t believe you cant join 4 verts to 2 other
it will always join one row to another one

if you parent something I don’t think you can change the parent alone this is why you do parenting.

but you can change the children alone.

not certain about the other points !

happy bl
