It would be cool and very helpful to add the following feature to the "poly length" - tool :

The feature should show relative measurements like in the example below.

So you have always a reference to the starting point.

The carpenter use the workflow with this Chain dimensioning very often when they work with a measuring tape p.e. to mark their different measurement points on the beams .

So the precision is much higher than adding individual dimensions.
