Field notes
Geometry can be built from boxes, cylinders, domes and sketched outlines, with editable variables and join or cut operations; the page also describes typing a building as a plain-text file. Pro imports DXF, STL or OBJ geometry and converts it for analysis. The listed PDF output includes settings, an air-terminal schedule, a 3-D view, plan and elevations.
