Hello, The wall that appears as 13 cm in the program is the weight calculated together with the plaster thickness of the 10 cm wall. If the thickness you are looking for as 10 cm wall thickness is the thickness excluding plaster, and there will be plaster on it, you can choose the 13 wall in the program."mhmt_ali":3dcpbdrd" said:Hi there is a 10cm wall in a project I just made. The program did not give the wall load of 10cm. How many do I need to enter. Also, how does it save for me to enter it all the time in the program. I would appreciate if you could help me about this issue. Good work.
