Elyptical Stair with Custom Stair Based

[Anonymous]

Hey guys, why am I encounting this problem by making an Elyptical Stair with the Custum Stair Based Function?Please see the image! I made a Fill and the Travel Line but when I click in the Design --> Create STair with Selection it tells me that my Travel Line should not connect to adjacent edges or nodes of the polygon Fills. Or if somebody cand tell me another Method for such Stair please tell me... Thkx for your patience!
