I have a drawing with nested parts that will be exported as DXF for laser cutting. I want to measure the total length of all the lines in that drawing (both inside and outside edges of every part), so a time and cost estimate can be made. It doesn't have to be terribly accurate. I know that the Measure tool can provide the perimeter length of each part individually, but there are many small parts in the drawing, and measuring each and every one of them and then adding up their perimeters is very inconvenient. Unfortunately it seems that Measure tool doesn't add up perimeters when selecting multiple parts at once.
What is the quickest way to get the total length of all the lines in my drawing?
