Topic moved - please don't just post in 'Archicad+'.
The plan view is a symbolic representation and it is relatively easy to control the lines and fills to make it look like the wall skins are wrapping into reveals.
The 3D is harder to control as it would need to manipulate the actual wall skins on all sides of the window - not just what it should look like as it does in plan.
The section should be showing the same as you see in 3D as it is actually a 3D view and not a symbolic representation like the plan so I am surprised if you are seeing reveal returns there.
There are a few other post here somewhere discussing this and probably even a wish in the wishes section if you want to look for it and vote (if it has a poll).
