Hey everybody, I am trying to build a Korean Hanok Roof in Solidworks as a proof of concept but I am running into an error when I try to cut shingle patters on a swept boss/base.  I have the sketch above the swept part and am trying to cut into it using a drawing made from a linear sketch pattern to speed things up (there will end up being about 200+ of these cuts).

Whenever I try to wrap the deboss to the part however it says that it is unable due to open or intersecting contours in the drawing.  When I try to use the sketch tools to find any open or intersecting parts the program crashes, any help? 

I am using the student version of 2018-2019 Solidoworks.  I've attached the drawing in case anyone wants to take a look at it.
