ORD - Slope direction pattern annotation problem - Model Detailing->Create 3D by slope to target tool

I am looking for some way to annotate slope direction patterns for the elements created by model detailing -> 3d Elements -> Create 3D by slope to target tool. Even the legacy tools would be a great solution. I have tried the workflow which works fine with corridor elements but I couldn't succeeded for the elements created by model detailing tools.

I have also faced with another problem regarding slope annotation where the corridor clipping occurs. As the corridor clipping tool only clips the 3d mesh elements feature lines which continue after the clipping boundary still be annotated. I wish the corridor clipping tool not only clips the 3d mesh elements but also the feature lines.

Any suggestion, work around or product improvement would be great.
