I'm having problems to create sections views. I'm trying to exclude a rib from being cut but I can't select the component I don't want to cut. When I try to select it, the whole part file is selected and not the component.

PS: I've found this method but it can't help me: http://www.javelin-tech.com/newsletter/tech_old/2007/december/article_isfastener.htm

Could someone help me? Thank you
