Hello, I have -1 basement in my project. When I first started the construction, I had 175/25 curtains, beams and columns in the corners of this floor. In order to make this floor a rigid floor, after entering the slabs into the system, I chose the side beams and turned my side beams into panels in the panel section of the beam. Then I selected these beams again and defined them as basement curtains in the properties section. However, these basement curtains are connected to my curtains in the 4 corners. When I take my drawings of the basement floor panel vertical opening, the curtains in these four corners do not provide integrity with the upper floors. How should I do? I will be grateful if you could help me.
