Please, please can we have better control over scope box extents? Once created a scope box has no edit sketch ability and won't respond to the align command. Basically you have nothing but very inaccurate dragging of control points with NO snapping.
We really need much better control. Even just being able to use align the top, bottom & sides of a scope box would give us the control we need.
At the moment, if you want to set your scope box extents 150mm below ground floor level (for example) you can only do this by creating a new scope box in a ground floor plan and then moving it 150mm down in a section,elev or 3D view, because otherwise you are just guessing.
