How to work with custom geometry in SketchUp
If I had received a model from architects (quite proper, must say), how can I create spaces and zones and further EP model?

The following videos show you how to model from imported plans and elevations. The basic approach would be the same from a 3d model. To make it easier to work with the imported model you may want to group it so you can add a plan/section cut as needed to see both it and the OpenStudio geometry.

Not really. I don't have plans and don't want to recreate the model. Rather this one https://www.youtube.com/watch?v=eIo74... The main issue here - we have to pick up all surfaces bounded the desired space and copy-paste into an OpenStudio empty space... This is quite weird and prone to errors... Any other method?
So is the model you want to bring in a single group defining the outside shape of the building? And if so is the goal just to break it into one space per story? There isn't an automated way to do this now but I'm just trying to understand your use-case to prescribe possible solutions. There is an experiential workflow that allows you to convert SketchUp groups to OpenStudio spaces, but in the end you still have to have the surfaces broken down by space similar to the video you refereed to. It will however save you having to copy/cut and paste, and can be quicker on large models.

I've finally decided to do it as described in this video http://www.youtube.com/watch?v=WWu_JD... Placing the envelope in one group and creating a one-zone model then splitting it up further. It would be great to have an instrument "select closed shell" when we can select surfaces and edges that form a closed shell with a pre-selected surface... I currently teach our architect how to model in SketchUp+OS to show them advantages of early energy analysis. Huge headache...

@Dinosaver, I've done a bit of OS modeling in an architect's Sketchup model by modeling "on top" of the Sketchup geometry as @David Goldwasser described. I'd be interested to know if starting with a one-zone model and breaking it up turns out to be quicker than building one from the bottom-up superimposed on the Sketchup geometry, combining spaces where you can along the way. I do like the "select closed shell" idea to select bounding surfaces for a zone.
