To access this dialog, go to Options > Project Preferences > Calculation Units.
This dialog allows you to set the units to be displayed
•in Interactive Schedules, for calculated values
•Autotext Labels
•in lists created with the Calculation function
•the List Areas add-on (available in selected markets)
Also use this dialog (Setup Rules) to set additional rules for computing the values of parameters listed in Interactive Schedules.
Note: If you are using the Calculation function, these settings will affect Text format lists only (not those based on a Graphic Template, which sets its own number format).
As you set each control, consult the preview.
•Unit: Click this pop-up field to select from various standard Measurement Units.
•Decimals: Click the pop-up field to select the number of decimals for the chosen Unit.
•Extra Accuracy: Choose this if you want to display additional decimal values as a superscript. The superscript value will be rounded off to increments of the number you select (e.g. 25).
Note: Extra Accuracy values will be displayed as superscripts only in Interactive Schedules. In Calculation lists and some add-ons, these extra values will be shown as extra decimals (rather than superscripts).
For example, here the number of decimal places used in calculating length (for the Wall Perimeter field) is set to two; but Extra Accuracy is turned on to 01, so that the next decimal value is also displayed, as a superscript, and rounded to 01.
Note on Volume Unit
Your choice of metric vs. imperial unit for measuring volume will affect the units used by the Density value and for the Embodied Carbon property of the project’s Building Materials.
See Building Material Classification and Properties.
Note on Angle Unit
If your chosen Angle Unit is degrees/minutes/seconds, click the Accuracy pop-up field to the right to select the precision.
