Hello,

I'm trying to create a roof with different eave heights, but Revit isn't allowing me to create it for some reason.

In the first picture is what I get without setting the "Offset From Roof Base" option. Then I try to adjust one of the two eaves by setting that option to 202 (measured in elevation view as seen in picture 2), but Revit is giving me the "Can't make footprint roof." error. If I set the offset to 201 or 203 I get the result in picture 3, but that is not ideal because it still has a 1mm gap.

Am I doing something wrong and how do I fix this?

Thank you!

Quite hard to understand what you are trying to achieve without an overall sketch of finished roof. But for Roof A with an eave level A, create a roof to correct plan shape, with the correct perimeter lines ticked/unticked to define slope and with the correct roof slope entered for each line. For Roof B with an eave level B, create a roof to correct plan shape, with the correct perimeter lines ticked/unticked to define slope and with the correct roof slope entered for each line. Two separate roofs. Unsure how Roof A  meets with Roof B it really depends on your architectonics. If roof is quite complex, you may need to consider using an inplace family as the roof tool can only do so much.

This is the footprint of the roof I'm trying to create. It's a single roof but with different eave heights. Revit is spliting it into two seperate roofs which I don't want. Is this possible using a single roof and not creating two seperate roofs like you mentioned?

Reove the slope defining mark from the higher roof.  It just needs one of the eaves to define the slope.
