Sir, thank you for your attention.As you can see, there are two types of problems in the panels that I need to place between the foundation beams and the columns. 1- it says the wrong panel column intersection, in the geometry control and 2- it does not appear in flight mode[/ quote] There are no panels in the project you added. The columns are not at the same level as the foundations. The panels are not at the same level as the foundations as I entered them. The panels appear in the perspective window and do not show any intersection errors. Also, create the basement height by adding the height of the ground floor. In this case, you do not need to level the foundation and columns. You can also define it by just giving the upper level. Also, after entering the basement curtains, use the object properties command and mark the line flooded/panel that does not continue to the upper floor in the static reinforced concrete tab.(When entering the basement curtains, you can specify the beam and floor edges on the upper level. Disable divide by intersections line in the auxiliary toolbar so that it does not split.) Separate We recommend that you update ca Ver 6.54.
