The Cross Section View is very useful for identifying beginning and ending heights for processes, tweaking supports, and other operations.
The problem is that the position adjusters are too difficult to use. The horizontal slider is only good for coarse adjustment, and the up/down arrow buttons increment by +/- 2mm: not nearly fine enough. What I end up doing is typing in a value, editing it, re-typing, editing...very tedious.
Please change the up/down arrow buttons to adjust in 0.1mm increments. (Or add this option under Preferences.)
