    When placing a curved wall under stairs in Revit the option to edit profile is not available as in straight walls, when the wall is selected. See Fig 1

    So one way to trim the top of the wall to the underside of the stair is to create a void to trim it. This is done using model in place.

    On the Architecture tab select the drop down arrow beneath component and choose Model in place. See Fig 2

    You are now in the modelling environment, so select void forms, then Void sweep from the drop down list. See Fig 5

    Choose the pick path button and select the underside of the stringer for the 3D path. See Figs 6 & 7
