If the sheet was uploaded manually into a project, you can set the scale of the sheet so that you can define which length on the sheet or grid corresponds to which length in real life. Sheets which are created from uploaded data, for example from CAD files, are already scaled correctly.
To simplify the description, sheets AND grids are referred to as sheet in the following explanations.
Sheets are displayed with icon in the project structure view of the Sphere XG Viewer.

of the sheet to open the dropdown menu.
Select menu item

The mouse pointer changes to crosshairs.

After you have clicked the second point, the popup Enter the real-world distance of the line is shown.
From the dropdown list, select the measurement unit you want (metric and imperial units are available).
