Grid Question

[genmills]

Is there a way to change where your editor focus is and the base grid mark, for example I want to make a second floor, do I always have to place objects and move them up everytime or can I just make a main base line at any height?

There's a button along the bottom, closer to the left, that allows you to set your height of focus. Also, on that same bar but more to the right, there is a button that looks like LT I think. That one turns on and off your tracking with the grid. If it's off you can move up and down freely. Hope that makes sense.
