I see that you already discussed that topic but unfortunately I am still struggling to overcome my problem. There is only one primitive which is faceing wrong direction. Its primitive with number 1800 which was created with sweep node (I attached file). I'm very new to houdini so I was wondering if it is possible to overcome without using VEX and creating new attribute ( maybe I made some mistakes before while creating curve). Is there any way to change its orientation to (0,-1,0) ?
