Recently I've updated to SW2018. Before (SW2014), with an assembly exploded, to collapse it, I was doing right-click in the graphic window and ''Collapse'' was appearing. Now this option ins't there anymore. But I've seen something new: ''Contour Sellect Tool''. If I select that, and after, right-click again, the ''Collapse'' appears. So I collapse the assembly and after I select ''End Select Contours''. So, instead of one right-click, now three.
What is this option? I don't really understand the purpose of this command.
Could you enlighten me please? Thanx.
