I normally overcome this problem by using the limited stair tool to produce a staircase with treads & risers only i.e. no strings. If required, strings/baserails/handrails/newel posts are added separately via a combination of complex profiles & beams/columns
The wall can then be constructed underneath the staircase & trimmed using SEO to give a clean line free look in 3D/elevation/section
Using the stairtool to provide the minimum structure instead of a complex profile/beam solution means you still have the option to display all the normal 2D information e.g. walk line, step numbers, rise & go etc in the floor plan view as required
