Hi everyone,
I noticed something in the Revit 2017 and Revit 2018, hope this will fix in next version...
These are two roofs, the grey one modeled with extrusion, the white one modeled with edit points. They have the exactly the same slope and elevations, but the white one is not showing the right thickness (400). The steeper it is, the bigger the difference it gets. Is it a common bug with everyone, or should I take care of something when modelling a floor with editing points? It's annoying not be able to trust a roof edied like this from now!
Any ideas or considerations on that?

I saw them Toan, but in the construction drawings you rely on the actual thickness, not on the projection, so I have to warn users of this possible problem. Still don't understand why they chose this way of programming the command, to me still remains a drawing inaccuracy.
Revit even fesses up sometimes...
Thickness may be slightly inaccurate. Dimensions in sections and details may not accurately indicate the Thickness shown in Type Properties.

I think the original intention of editing sub-elements of a roof is meant for flat roof with a variable thickness layer, a flat bottom and non-flat top.

This is correct. The way the tool was "programmed" was to solve a particular problem. So the math and geometry is worked out as if the roof is flat and measurements/offsets are based on that. Because of the difference in projection the geometry of a sloped roof using a slope arrow or sloped edge is going to be different than when you offset an edge using the shape editing tools. To say it is "inaccurate" may not exactly be a fair characterization. It is not the SAME as when the geometry is projected from a parallel plane instead of a horizontal one.
The tool even has a warning about it when you have a fairly significant shape edit in place.
It is important to understand what the tool is doing and to use the right tool in the right situation.
