Full title: How to maintain wall height when using Roof by Footprint and extending roof beyond walls

hi

I have a drawing of a building with a shed roof, only two wall heights have been defined and i don't want to go about calculating the slope. I need help figuring out how to maintain the specified wall height when using "Roof by Footprint" and extending the roof beyond the walls.The problem I have is that when I extent the roof to stretch out beyond the walls Revit changes the height of the walls.

I am using a slope arrow, since this is the only method i can find where i don't have to define a slope, but i'm pretty new to Revit so i might have missed something.

I have added some pictures of a simplified example.

#1 Just a quick overview.

#2 Added the roof so that it doesn't extent byond the walls. The walls have the correct height.

#3 Extending the roof beyond the edges of the walls and revit changes the height of the walls. Have added two pieces of wall with the correct height to make it easier to see what's happening. It can be seen that the wall at the low end have been made higher and the wall at the high end have been made lower.

You don't have any valid reason not to use the slope setting.  If you don't have a conventional slope, simply use an equation to express the slope and let Revit calculate it.  Height/Span  Then you can specify the overhang before you sketch the roof.

Thank you for your reply. I posted on autodesk forum too but got impatient, in the meantime i got what i needed there. For anyone having the same problem, go here https://forums.autodesk.com/t5/revit-architecture-forum/how-to-maintain-wall-height-when-using-roof-by-footprint-and/td-p/7084008

Roof - Inner loops of a footprint sketch may not have slope-defining lines.
