- Scroll the axial view to the level of the alveolar crest.
- Click Trace span…, then click along the middle of the ridge over the teeth you are planning, about one click per tooth and at least three, from one end of the segment to the other.
- Double-click the last point. The sections are made at once; the tab shows how many (for example "10 · every 3 mm").
- Click Show sections to open them over the viewer. Press Esc or the collapse button to go back.
- To change them, set Spacing (gap between sections), Width (how much bone each shows) and Slab (thickness), then click Regenerate. Clear span starts again.
