Hello, The determinations for data entry in your project are as follows; -3. The floor edge is drawn under the K04 beam on the floor. (Caution in geometry control) Tile edges are drawn only to create a closed area to empty edges. - Again, the spring floor edge of the D14 floor is not connected to the K04 beam. Therefore, there is an error in the slab formation. -Circular column defined in a coordinate unrelated to the project. (P17) Apart from that, the short side dimensions of the column can be enlarged, the material strength can be increased, a column can be added to the carrier system, etc. for the Max pursantaj (M) warning in your columns. Good work.
