SubD & Vertex tools question

[OpenConcept]

Hey guys!

I have installed subd, and it is mega cool!
I am wondering if SketchUp along with subd can handle this comfortable chair?

If not, what should i do with the holes I'm getting when working with Vertex tools.
Everybody is amazed by vertex tools but i don't get it.
When i extrude with ctrl+left mouse i get a hole.

Cheers

Symmetry is not possible in SU (weld+subd of two mirrored components). To subdivide the middle part you have to combine both sides in one group/comp.
