Hello there; In fact, defining the reinforcement curtain from column to column does not allow you to capture the edge/corner of the mantle element anyway. In the screenshot below, the 1st definition is made from the reinforcement curtain column to the column, and the 2nd definition is from the mantle to the mantle. If you look at the analysis model, you will see that the 2nd definition is incorrect, there are no rigid connection elements between the column and the wall. If we examine the drawings for these two definitions, you will see that the drawing of the second definition is also wrong. Best regards.
