How do I move an object through a workplane in TinkerCAD?
1) When you click on an object notice the black cone on top or the bottom of the object you select. There is only 1.
2) You can left click and drag it to move it up or down.
3) The black cone will ALWAYS move the object through the workplane. Notice here I have moved the workplane and the location of the cone changed.
4) See, I can now move the shape through the workplane in this direction, where as before I could move it up or down. Try changing the workplane to move the cone in different ways.
