Hello, Colonies that are not connected to the dome will not be connected to the rigid diaphragm no matter how you enter the data. Your calculations are correct and there is no problem with data entry. Bar deformations in the perspective window are displayed using deformations calculated at the nodal points. The deformation values at the nodal points of the column (bar) are correct. You can enter the columns that are not connected to the beams and slabs separately on each floor or by giving an elevation. If a floor connection is not established with the nodal point on that floor, that point is not connected to the rigid diaphragm. However, when the column enters by giving elevation, a nodal point is not formed in the floor plane and the deformation at this point cannot be calculated directly. Therefore, deformations calculated directly and calculated by interpolation are not exactly the same. This difference is only a matter of display. It does not affect your build's account. This display-only situation has been noted to be corrected in the next version. Good work
