Which tool is used to calibrate the scale using a known distance?

• A. Calibrate
• B. Align
• C. Snap
• D. Measure

Answer: (A)

Calibrating the measurement scale by using a known distance is about telling the software how long a unit should be in the drawing. You use the Calibrate tool: pick the two points that represent a distance you know in real life, enter the actual distance it represents, and the program computes the scale. Once calibrated, all subsequent measurements reflect that real-world size, giving you accurate takeoffs.

The other tools don’t set the scale. Align adjusts how markups line up with geometry or pages, Snap helps your cursor lock to points or lines while you markup, and the Measure tool performs measurements after the scale has been established.
