What's the SiteWorx/OS workflow, tab by tab?

The tabs run left to right and that's the order you work through them: 1) Project — name the project and configure boring log / trench defaults. 2) Drawings — open files, set scale, align multi-page or multi-file plans, define optional GPS control points. 3) Takeoff — digitize project boundary, topsoil strip and respread, contour lines, point and area elevations, sloping design lines, trenches, boring logs. 4) Calculations — compute volumes. 5) 3D View — review existing and proposed surfaces with cut/fill colored. 6) Cross Sections, Grid Data, Soil Analysis — derived views and reports.
