Set Scale or Calibrate

Capture a known distance between two objects and then calibrate or adjust your sheet to reflect these dimensions and measurement units.

You must specify the scale on a sheet before you can perform takeoff on it.

To Set Scale on a Sheet

1. Click Scale not set at the top of the sheet in the viewer. Alternatively, select Calibrate from the viewer toolbar.
2. Select two points on the sheet Note: For vector-based PDF sheets, you must snap to two points during calibration.
3. In the Calibration dialog that opens, define the size and unit type of the dimension you just drew, then click Set calibration.
4. The scale for the sheet is now set and will be set for anyone viewing this sheet in the project in Takeoff.
