I just started using Softplan again after 15-20 years (last version I used was 7) and have installed 2014 plus Softlist. I am trying to set it up to reflect the way we build houses but I am a little stymied by the disconnect between the wall definitions in Softplan and the material definitions in Softlist. I created a new wall (copied from 2x6/siding) called 2x6/1.5"EPS/siding which is sheathed with 1-1/2" expanded polystyrene. I created the material definition for the EPS but I cannot for the life of me figure out how to reference that material in the wall definition for this new material and costing. I am probably just missing a step but after 4-5 times through the manual I cannot find the solution. Can anyone point me in the right direction?
