Hello Mr. Ismail. I wanted to share some of my views about the latest version 10.05. I have been an Idecad user for many years. I am also an amateur software developer. Sometimes I want to share about the İdecad software and sometimes about the regulations as far as I can see, even if I want to share in the form of incomplete, error or advice, most of the time, unfortunately, I neglect it. This time I resisted and was able to write a few lines. * In version 10.05, the program closes when the grid and border settings are clicked on the drawing screen. * I think a very serious revision is needed in the definitions of U, L and T type curtains. You have brought a definition of a group, but based on the statement that it will be defined as a single element in the regulation, Civil Eng. friends do not accept group definition. They have difficulty understanding etc. I think this can be solved in software. For example, can the names of the elements that make up the U curtain be the same and printouts can be arranged depending on one in the calculation reports? U etc. I think it will be a radical decision for İdecad to change the method in section definition. But in my opinion this seems inevitable. *When choosing the building height class, a button can be placed to subtract the attics from the building height total. I think the regulations allow it. Hoping to see you again
