WHEN I OPEN THE PROJECT MADE IN VERSION 8.504 BEFORE WITH 8.61; IT SAYS RIGIDIZED 8-POLLAR JOINTS WRONG (INCORRECT COMBINATION. STEEL BEAM SHOULD BE ASSEMBLED TO STEEL COLUMN PLATE.). ALSO, WHEN YOU CAN SEE THE COMBINATIONS SEPARATELY IN VERSION 8.504, IT SHOWS SOME OF THEM NOW, IT CANNOT LIST THEM ALL. IN THE NEW VERSION, THE PROBLEM OF SLIGHTNESS ARISES IN THE STEEL CROSSES (8,504 DID NOT HAVE) BUT THE REPORT IS NOT LISTED IN THE WARNING LIST ON THE FIRST SCREEN. I CANNOT FIND WHERE TO CREATE A CONTOUR AREA IN THE NEW VERSION. ACTUALLY, THERE WAS A PROJECT OF 30 MB, I WAS SOLVED IN 8.504 BUT. IT SAYS MAXIMUM 4MB. IF YOU PROVIDE AN MAIL ADDRESS, IT MAY BE SUITABLE FOR YOU TO LOOK AT THE DIFFERENCE BETWEEN THE TWO VERSIONS.
