Editing Units

Highlight the name of a selected unit to edit its attributes using the controls in the right-hand side of the dialog box.


The top (uneditable) row displays the name of the database the selected unit belongs to. Edit the name of the unit in the text field provided.

The five formatting options in the center of the window control how the units will be displayed in the plain text list. Please bear in mind that Graphic Templates can override these settings.

1.Check the 'Justify Left' checkbox for the calculated value using the unit to be justified to the left, causing the remaining characters defined by 'Width' padded with SPACEs. As default, all Units are right-justified and character places on the left are padded with SPACEs.

2.Checking the 'Plus Sign' checkbox inserts a '+' sign as the first character of the values string, allowing one character less in the number value.

3.Checking the 'Space before positive values (if no Plus sign)' checkbox places a SPACE character as the first character, if no plus sign is specified to be placed, making it possible for all values to align well to the left.

4.Checking the 'Don't display Zero wholes' checkbox will not display the Zero whole and the decimal separator, in case the absolute of the displayed value is between 0 and 1 inch. This applies to values displayed in decimal format. Such can be the case with width and height of Windows and Doors, for example.

5.Check the 'Display Zero inches' checkbox for Zero to be displayed when the absolute of the displayed value is between 0 and 1. This applies to values displayed in Imperial format.

In the Width text field, set the number of digits to be used when displaying the unit. Note that the Width value cannot be less than three.


Choose the desired number of decimals places to be displayed in reports from the Decimals pop-up list in the bottom right corner.

Use the Conversion Unit pop-up at the bottom of the dialog box if the selected database unit is different from the one chosen in the Options > Project Preferences > Calculation Units & Rules dialog box. Choose “none” from the pop-up list if using this option is not appropriate. Selecting the proper conversion units decreases calculation errors when database units and calculation units are different.

Note: ARCHICAD calculations are performed according to the settings of the Calculation Units and Rules dialog box (Options > Project Preferences > Calculation Units & Rules) except when instructions in Graphic Templates override the settings.
