Using
The plugin calculates the total length of selected lines, polylines, circles, arcs, ellipses, and splines. Objects can be selected either before launching the plugin or while the plugin window is open. Calculation results are displayed in the plugin window:

The upper part of the plugin window displays the total length of the selected objects, the multiplier, the scale, and the final length calculated using the multiplier and scale. The final value field cannot be edited manually. Clicking it copies the final value to the clipboard.
When entering multiplier and scale values manually, either a period or a comma can be used as the decimal separator.
The contents of the Length by Objects section, as well as the blocks for individual object types, can be collapsed and expanded using the buttons on the right side of the corresponding headers.
– insert the result as single-line text:Insertion point: – specify the insertion point for the single-line text.
– insert the result into a table cell:Select table: – select a table.
Select cell: – select the cell in which to insert the result.
– export the arithmetic mean (including rounded results) for each object type and for all selected objects to a txt file.
– export the result to a txt file.Entities – list of selected objects.
– zoom to fit the current object on the screen.The
button in the upper-right corner opens the plugin settings:
Decimal separator – specifies the decimal separator used when displaying results.
