One label per wall height. In MeasureSet a height belongs to a label: type it on one run and every length with that label takes it. So name labels after what changes the math, such as Walls 8 ft and Walls 10 ft, or Partitions and Shaft walls, and give each its own color so the plan reads at a glance. The label library keeps those labels, colors, and heights for the next job on this PC.
Tracing the runs. Calibrate the sheet first and check one known dimension with the segment tool. Then trace with the length tool, clicking corner to corner along the wall. One mark can turn as many corners as the wall does, and Shift keeps 45-degree steps. New points snap to the corners of runs already drawn, which keeps the takeoff joined at intersections without counting a corner twice.
One face or two. Wall area in MeasureSet is length times height, which is one face of the wall. If a partition gets board on both sides, double that label in your spreadsheet, or trace the run under a second label for the other face. Exterior walls that get board on the inside only stay as they are.
Openings. Draw a short length across a door or window with the same label as its wall, tick Deduct from the total, and type the opening's height. An opening keeps its own height; the wall's height does not reach it. A 3'-0" door at 6'-8" takes 20 square feet off the wall, and the deduction shows as its own row in the Marks list, in the export, and on the marked-up PDF.
Waste. Type a waste percent on any run of a label and it applies to every length with that label. Totals show the net area and the figure with waste side by side, so the allowance is visible instead of buried in a formula.
Ceilings. Measure ceiling board as an area with its own label, using the room tool for closed rooms or the area tool for anything open. Areas also report their perimeter, which helps with corner bead or ceiling trim.
From square feet to sheets and hours. MeasureSet stops at quantities. It has no assemblies, so converting wall area into boards, fasteners, tape, mud, and labor happens in your spreadsheet, for example dividing by 32 for four-by-eight sheets. Keep in mind that a measurement is only as good as the calibration and the drawing, and that heights come from the sections and schedules you read, not from the floor plan.
