A common request I receive is “how do I get my dimensions to show in mm and my areas to show as m2″. The first thing I refer to is the fact that views in the “Navigator -View Map” control the output of dimensions. Under the tab “2D/3D Documents” there is an option for “Dimensions:”. The default option is set to “Plain Meter”. If one changes this to “Plain Millimeter” then both dimensions and area are displayed as such. The solution is to set your own dimension preference using the Project Preferences. To do this from the Menu > Options > Project Preferences > Dimensions… Select the option “Plain Millimeter” but change the button “Area Calculations” = to “meter”. This will then display name as “Custom”. You can rename “Custom” by clicking on “Store as…”. In this example I called it “Dim = mm & Area = m2″. If you now return to your floor plan you will see the result.The last important step is to open up the “View Settings” and change “2D/3D Documents” > Dimensions to ”Dim = mm & Area = m2″. This will then control the display of dimensions and areas to your specification.
