The report generator can only report dimensions of group and component bounding boxes. If you make components for each edge you should be able to get the lengths of each one. Since dimensions in Report Generator are given by axis I would set the same axis for the length in each component.

Here's a quick example. Red axis set along the length of each edge.

I see, this solution is cool haven't think about that, the problem is making a group and setting the axis for every line will be kinda tedious when you have a full house to make, also when you have arcs you don't get the real length of the curve (this is how usually the ceiling electrical lines are represented in 2d plans wich we import to SketchUp).
Anyways I tried this solution and it worked so I will have it as an option, Thanks!

Hello, first time posting here!
I´m making a calculation report on a house's electrical installation.
For the wiring, made a component containing a group of connected lines. When I select all of the connected lines the "entity info" tray shows up the total length of the wires. This is the length we are looking for our calculation to use in the "generate report" feature.
The problem is when I group or make a component out of the lines, this lenght is lost, and I cant get it to appear with any of the standard classification types. Any Ideas of how I can get this lenght in a report?
