in the model I would like to have a section view (from the right plane for exanple) of all my assembly except for one or two subassemblies (or components). Is it possible with Solidworks?
Use the selected component option.
Forgot to mention that this is on SW2014 and onwards.
I have Solidworks 2013 and with my version I think this option is only avaliable for the drawing not for the model.
As Deepak noted, you can select components or bodies to include in or exclude from a section view as you are asking but it's new functionality for SOLIDWORKS 2014 as is the ability to create a Graphics-only section view. The images below show the PropertyManager from 2014 and a rendered version of the section view.
You can always create a new configuration and do an assembly cut with the feature scope set to only those components you want sectioned.
