Hello, I have been preparing Proje one retrofit project for 2 days, but I am having more difficulties than the old version. I even faced many different situations. I request friends who have knowledge about the topic I opened here to help me... 1-) In the old version, while defining the column beam flooring and sheathing concrete class and steel class separately, why is there no such possibility in this version. 2-) Can't the material be defined after the first entry? .. When entering the colon at the first entry, I was given a message, "Define material," in the automatic message. For example, I wrote reinforced concrete and entered the concrete class and steel class. Later, when I wanted to define a different section, I could not define a different material from anywhere else, I could not find it 3-) Kolnon does not draw the sheathing details correctly. While the jacketing of the example is in the -y direction, he turned the u-shape 90 degrees in the drawings and gave the drawings in the X direction. Drawn outside the sheathing column can cause this error. 4-) While drawing the reinforcement curtain, why doesn't he wrap the columns inside and draw the details therein... 5-) In the sheathing, he does not give the anchorage detail and the vertical section, as it does not give in the longitudinal section? How can we get this done? There are many more problems like this for the program... Could the ide structure show an example of preparing a retrofit project visually?
