Inheritence with node3d

[dan12345]

I wanted to create my own object ( a table, a few children nodes connected
to it, and a few children nodes connected to them ), and to
extend the functionlaties of my object, whilst keeping all the node3d
functions ( such as visible, rotate, etc... ) available.

So is it possible to inherit from the node3d class? If so, how do i do it?
thanks
