Click the TotalLength ribbon icon or type TotalL/TotalA in the command line to open the TotalLength dialog/TotalArea dialog.

Check the types of objects to be included in the TotalLength/TotalArea calculation. Check ALL LENGTH OBJECTS/ARCS in the TotalLength dialog to include all objects with a 'Length' or 'Arc length' property when opened in the Properties Bar. Check ALL AREA OBJECTS in the TotalArea dialog to include all objects with an'Area' property when opened in the Properties Bar. Unchecking a type of object while ALL... is checked excludes this type from the selection, i.e. the selection contains all objects with the desired property except those of the unchecked type.

Check the Insert labels box and set the Text height value accordingly to your drawing if you want each selected object to be labeled with its length/area.

Click the Select objects button to make a selection. Use whatever selection method you want, TotalLength+ filters only the objects of the desired types. Right-click or press ENTER to confirm your selection is ready. The TotalLength/TotalArea dialog is opened again, the total length/area of the selected objects appears in the TOTAL LENGTH/TOTAL AREA field. The value can be copied to clipboard. Click the Select objects button again for another TotalLength/TotalArea calculation.

Select type(s) of specification table(s) if you need any. The following tables are available:

• By Layer - lists the total length/area of the selected objects of each layer
• By Color - lists the total length/area of the selected objects of each color. Index colors are represented by number, true colors - by RGB list, color books - by name
• By Type - lists the total length/area of the selected objects of each type
• By Length/By Area - lists the various lengths/areas and the number of the selected objects of each length/area

Click  the INSERT LIST(S) button to insert the selected specification table(s)in your drawing or click the OK button to exit the TotalLength/TotalArea dialog without inserting tables. The value in the 'Text Height' box and the current table style are used for the tables. You can also press the INSERT LIST(S) button while no objects are selected.

All the values returned by TotalLength+ are of the current Units type and with the current Units precision.
