I've been using TinkerCAD for a long time. Mostly everything I created. Lately I've been downloading and attempting to modify STL models made by other designers to fit my needs. Big problem with TinkerCAD is its limitation of 25mb files and too complex meshes when importing. As to setting the grid: there is a button in the lower-right corner of the screen named "Edit Grid". It simply pops up a dialog to enter the X and Y dimensions that you want the grid to be.
