I'm trying to re-do a roof (first attachment) that someone else in the office has already modelled once, but which isn't appearing correctly. The thickness is supposed to be 416mm, however it only measures that dimension when measured vertically in section, not perpendicular (refer attachments 2 & 3). In construction, materials don't 'flatten' when sloped, yet Revit seems to be doing this to me (refer 4th attachment for Structure list in Type Properties). It's also connecting the different roof planes with vertical cuts (again refer 2 & 3), rather than at an angle - possibly the source of the problem.
It was originally built as Roof by Footprint with Modified Slopes and No Defining Elements. Could someone please help with a better way to model such a complex roof, with ridges at funny angles and roof planes that 'hinge' off already sloped roof planes?
Thanks!

Oh boy. I know all about ridiculous roofs, and I went through what you're going through.
For the longest time, up until not too long ago, i was able to get by with footprint roofs, and slope arrows. But sometimes... some buildings... have insane roofs. See attached pic for the project I had to deal with.
What you're going to want to do is turn off all the slope arrows on your roof. "does not define slope" to all. When you do this, you'll see a button appear at your "modify roofs" tab, called "modify sub elements" and the corrosponding "add point" and "add split line."
To be clear -- start with your footprint, but with no slopes. Finish the roof while it's flat. you add/modify points without going back into sketch mode.
Now, you can modify the heights of specific points, and ridge lines, tailoring your roof to very very complicated shapes. HOWEVER, it is less easy to be absolutely precise with this method. And if you're annoyed by all the interior lines created by this method, use the linework tool, and invisible lines, to hide the excesive number of interior edge lines.
hope this helps.

Thanks itsmyalterego,
I tried your method and it's still joining roof planes of differing slopes with with vertical joints and thus measuring the depth of the roof vertically instead of perpendicularly.
I feel like there must be some option that just needs to be ticked or unticked somewhere in the properties to make things right. Or maybe there's a 'complex roof' system family instead of the default 'basic roof'?
