Gable wall projected into adjacent room fixed.  This was resolved by using the same technique to fix the gaps in dormers except an isometric horizontal wedge shape was used.  The dormer gap is fixed with a inverted wedge shape.
 
 

Thank you, thank you.  I originally used the " Material Painter" instead of the " Adjust Material Definition".  I applied the AMD tool and it reset the wall back to the original drywall color as default.  All new walls come in with the drywall color or the room color.  Also, the "Wall Specification Box" now has the drywall as default and not the repetitious pattern of the painting.
 
Thanks

Attached is an image which shows a dormer with the gap problem (same as above).  I fixed the gap with the inverted wedge technique and cleaned-up the corner using a "box" shape.

Thanks, I thought about that; but, I was hoping for a common wall: however, your suggestion provides a very satisfactory solution.

Thanks all,  found it

Problem Solved
 
I created the truss three different ways: 1) AutoCad 2D line drawing which was imported into Sketchup, expanded to a 3D SketchUp model and saved; 2) AutoCad 2D polyline drawing which was imported and also expanded to a SketchUp 3D model; 3) created the 3D model in SketchUp and saved.  All three models were imported into CA with same distorted surface (faces) results but with somewhat varying distortions.
 
After many of hours of frustration I stumbled on .3ds format which is a native 3D model file used by AutoCad Studio for rendering.  This is one of several 3D model files which SketchUp can export to.  I exported all three above SketchUp files using .3ds.  All three imported perfectly in CA.  See attachment
 
Apparently, CA does not handle the SketchUp format, .skp, as well as it does .3ds; or, the SketchUp model is not as robust as the .3ds file.
 
If anyone creates a SketchUp model for CA I suggest that you export the SketchUp model using .3ds and not SketchUp native format .skp.
 
I hope this is of some value to others.  I understand all of the above may have already been repeated and I just missed it.

My final results.  See image.
 
The 2nd floor 78" high;  I used soffit per your suggestion to obtain 96" ceiling for images. The garage storage area 56" high; used soffit again.  All attic space 95-5/8.  The front dormer is manual and the rear dormer is automatic.  Both dormers are set back 2' from first floor exterior wall.
 
It appears all exterior and interior images are correct.
 
Thank you for your help!
