I have created custom constructions and materials as I work in NZ and none of the standard libraries won't work for me, but when I run simulations none of my constructions come through. The only way I can get around this is to manually input all of the surface and sub-surface constructions one by one in SU. This is extremely time consuming. I notice if I drag standard constructions out of the library and drop them into the construction sets EP recognizes them right away. Does anyone have an answer for this?
