curved objects from polyline in vertical plane

[djnral]

I have Home designer Pro 2024 and have watched the videos for making a custom backsplash,  I want to make a custom backsplash from a curved polyline. This will eventually turn into a curved timber beam.  I draw the polyline I want in an elevation  so it is nicely in the YZ plane.  When I convert the polyline to a custom backsplash, it moves it to the XY plane.  How do I keep it in the YZ plane so I can then give it a thickness and material to resemble a curved timber?  is there an article I have not found yet?  Also, is there a way to extrude that polyline?  or is that only available in the really high end version?  I have built most of my timbers from boxes, but a curved one is giving me fits.  Please point me to a video or a paper or an article or maybe it cannot be done in Home Designer Por?

 

Thanks
