Thanks Thom, I could not remember where I read about your method.

I think I described it more in depth another place - but I could not find that thread now. Think it's in the V-Ray section somewhere...

Thanks, I will try this out. Funny how what appear to be very difficult techical issues are often solved by very simple solutions.
-
I often ask questions but thought it only fair to post an answer.
So, I tried what was suggested over numerous trials until I got a successful result ready for later use.
Key points I found for a successful cut section render were as follows:
Omni light (not rectangular light) with high intensity setting set as a virtual sun.
Sufficient apetures
Good position of the Omni light to optimize shadow lenght and depth and interation in the spaceAll sunlight and daylight turned off
But found this to be a bit dull and many dark spaces on the plan so to compliment:
Rectangular light set as a ceiling at a very low setting to give an ambient background/backup illumination.
And the technique works a treat, thanks.

Good to hear alternative setups.
-
If an alternative it was probably because I didn't ready your solution well enough.
But if it is different then cool as there is more than one way to do it!
-
I used Sun/Sky as external light source.
Omni and Rectangle lights as interior Light sources.
Then it was the ceiling face with the side facing the interior a solid materials, and the other side facing the camera 100% transparent.Maybe you can post some screenshots of your results when you tried to follow my method? That way we might be able to see where I could clarify my descriptions.

Attached was a 2 min model constructed for testing, giving in principal the results wanted.
Would need to be toned for a real project.

You forgot to attach?
