Hi, I am trying our the EstMep and after inputing the fittings like elbows etc. in the Items tab their DIN area in equal 0,0 the rest of the areas like LUKA are showing. Does anyone knows why it is so? Also in the Database>Pattern options I do not have the Standards tab - does anyone know how to reach it? I am using the metric content V7.03 and trial of EstMep 2016. In advance thanks for the answer.
