Is it possible to exclude a part from sectioing in Composer. I know how to do it in SolidWorks but not in composer.

In the image below I don't want the robot to be included in the section.

And following on from that, is it possible to create a section view and then use the Digger tool to zoom in on an area. At the moment, after I create a scetion and then press space bar to get the Digger tool up, the section disappears.
