Re: Analysis error when IDECAD8 is saved as old version Hello, you know that in version 8, the wall height can be entered at the desired value. However, in version 7, there is no concept of wall height unless you read the data from the architectural program, the total wall value is entered. In your project, you have defined wall heights of 2 meters and 1 meter as far as I can see in some beams. When you save the project as 7 versions and open it again, the defined wall heights are not known for the reason I wrote above. 2.5m is taken by default. This is why the difference occurs. If you redefine the wall heights as you first entered, the difference will disappear. Can we find out what is the reason for you to enter the project at 8, save it as 7.020 and analyze again at 8?
