ORD - Show existing pavement in XS

Let me rephrase my question.  After reading it today I see that it wasn't very clear.

How do I model existing pavement in ORD 2020 R2?

Similarly, how do I show cells in cross-sections to indicate bldgs, ROW, fences, etc. in ORD.  In SS2 I used Draw Ancillary Features to accomplish this.

In Power Geopak SS2 I used an old criteria file to draw existing pavement onto cross-sections.  It used the Draw Trace command to draw existing pavement 3" below the existing ground using existing EOP elements found in a separate dgn file as the LT/RT edges of existing pavement.  Our agency deducts the volume of pavement removal from the excavation volume since we pay for pavement removal on a "per SY" basis.  We don't want to pay for it twice.            

Similarly, how do I show cells in cross-sections to indicate bldgs, ROW, fences, etc. in ORD.  In SS2 I used Draw Ancillary Features to accomplish this.

This image shows one of my SS2 cross-sections.

I saw a video where they added a milling and overlay component and point controls to tie it to existing pavement edges. Unfortunately, I do not recall the location or any link. But if you use Google you might find it.

I believe that the Ancillary features can now be set as the cross section aspect of the feature definition.

Existing pavement can be modeled a few different ways.  You can create a template that uses overlay components that follow the surface at a surface depth.  The width of the template can be controlled by point controls or horizontal feature constraints. The other option is to create a terrain of the existing pavement and apply a surface template to the terrain.

Ancillary features can be drawn using civil geometry (horizontal & vertical) with the proper feature definition assigned.  Take a look at the training and examples workspace, training imperial workset delivered with the software.  Look for the Feature Definition called E_ROW, it is set up to display the right of way cell on the cross sections.
