I am new to product. 
After installing, there were no updates to 2015. 
I am trying to do a plot plan as first task. 
When I enable Select Objects the cursor does not show selection arrow icon, but instead shows the enable Edit Behaviors / Edit Object Parts icon (looks like it without a checkbox). 
I seem to be able to select multiple lines (they show an enclosing box), and do a Snap Settings / Object Snaps. 
However, the lines are separate (not polyline). 
How do I get a polyline object?
