The Linear tool measures walls, edges, footings, pipes, and other runs. Check the drawing scale against a known dimension before starting.
Start a linear measurement
Select Linear in the bottom toolbar. You can also open a wall type found under On this sheet and click Measure.
Click along the run to trace each corner or change in direction.
Click Finish or press Enter.
Name the measurement in Properties.
Calculate wall surface area
Select the measured line to open Properties.
Choose Wall.
Enter Wall height, using the units shown and a height from the drawings.
Click Done.
Wall area is calculated from length × wall height. Choose Length when you only need the run, or Volume when thickness is also needed.
Measure a rectangular room
Turn on Draw boxes or press B, then drag corner to corner. All four wall sides are added. Click Finish to complete the box.
Add more walls to one measurement
Use Add line to add more runs to the selected measurement. With Separate segments, each pair of clicks creates its own run. Finish when all walls are included.
Smart Scopes and quantities
Use the suggested Smart Scopes in Properties when you need assembly quantities. Set each scope’s options to match the drawings, then click Done and review the outputs in Quantities.
Hold Shift for straight lines. To temporarily turn snapping off, hold Control on Mac or Windows.
