CST studio suite 2010 -design studio

Hi all,
please is there anybody that knows where to find a detailed description of how design studio works? Using the embedded examples, in respect to other pcb capture/simulation software it appears to be very poor in component library and very cumbersome in placing\editing wires, not to speak for mixed dc/ac simulation as needed, for example, to test a simple rectifier circuit. For sure there are lots of things that on-line help doesn't deal with and that, consequently, I don't know.
Best regards
