Hello everyone I'm searching to automate a task in my office that always takes me a long time. 
I'm trying to calculate the linear meters of screed edge strip boards but I do not need to have them in the drawings. 
I have made a single slab to represent the screed for each floor and all the slab materials have inferior priorities to the wall materials. This way the walls section the screed. 
I would like to calculate the linear meters of intersection between the slab and the walls with a schedule. is it possible or is there any other way that does not imply to model de screeds in 3d? 
Tanks in advance
