Being new to Revit, I am unsure how to work around this issue of creating a custom stair. I am currently working on an as is drawing of a house and want to simulate the same main staircase. I will attach a few screenshots to further explain my issue, but essentially I get the error that it could not generate the surface for the stairs. I did have it working before, however it was not exactly along the curved wall and the bottom riser was extending through the wall past my boundary line. I moved the boundary lines to their more appropriate location and started receiving the error message. I would greatly appreciate any help someone can give me to create this stair.
