Hi, I'm justing getting started with SW 2015 and I have a couple questions:

1) Is there a way to step back when using a multi-step tool? For example, suppose I’m sketching a centerpoint arc. I select the center correctly, then I make a mistake selecting the first outer point. How do I back up one step to correct my mistake (without having to re-select the tool and the center like if I use Esc)?

2) Suppose I'm sketching a line. When I select the Line tool, the PropertyManager lets me select orientation and some other options. Once I place the first point it shows other things like Add Relations, though they’re greyed out. Once I place the second point those options are no longer greyed out, and I would like to go add a relation to the line I’ve just made, but as soon as I move the mouse it decides that I want to continue adding line segments. I can hit Esc, but then I have to go back and re-select the line to edit it. Is there a way to exit the Line tool after I’ve placed the second point so that my new line is selected and I can shift-select other entities, add relations and so forth straight away?

Thanks for your help.
