If the Sketched Bend feature sketch line is close to the edge, and if the feature bend radius is large, there is a possibility for the feature to “bend” adjacent edges as well.
In a worst-case scenario, this problem of “overbending” occurs when using the Material Inside option (Figure 15c). In such cases, when you create the sketched bend feature, the position of the Sketched Bend Line is at the outer face of the bend. Therefore, to avoid this issue, give extra consideration when folding a tab if the sketched bend sketch is close to the edge. The Sketched Bend Line Distance must be equal to or greater than the Bend Radius plus the part thickness.
