And i need summ of length of this lines, than i can recalculate it with scale and find length corresponding with plan. So i just need tool to merge length of line is it possible? Thaks for all who helps me!

Hello! Is it possible to calculate length (in pixels or in centimeters) of all lines with known parameters (color, brush width) in the drowning? Maybe any tool present to calculate length of all lines in the layer? sorry for my English
