Pointcloud to Surface

Hello, everyone! I want to use rhinoresurf plugin to implement pointcloud to surface, but I do not know how to adjust the pull orientation (dx, dy, dz) , I’ve tried it many times, but the surface doesn’t fit well. Can anyone tell me what the pull orientation (dx, dy, dz) should be to get a good fit surface? Thanks!
Figure 2 is the result I want.
