SW 2017, not sure if this is a bug or my download. Whenever I make a sketch, i can click on for example the line tool, and I am able to zoom in and out and around before i place the starting point of the line. When i try to do this for a conic/spline: once i click on conic or spline i am unable zoom in or out until I place the first point of the spline, after which I can zoom. Anyone else have this issue also?
