Note: Directions of designed reinforcement, in general independent for the upper and lower surface of the member, can be visualized by symbolic arrows (single arrow for each direction) using the option [Drawing directions for design] in View parameters setting. The arrows are drawn per member or individually for each mesh element, depending on the selected local coordination system of the member. If the LCS is the same for all mesh elements, then the arrows are drawn only once for the whole member near the centre of gravity. Moreover, when results related to specific reinforcement direction are presented, only the arrow associated with this direction and surface is automatically drawn. The visualization of the arrows can be modified by Colours/Lines settings to distinguish each direction specifically for better orientation in results.
