結果要做一個實際的東西作不出來，做到要讓管子變形就卡住了，
All I am doing is selecting all the vertical edges and using the "connect" tool to add more segments, then moving them where I need them, then scaling in the middle section to create the dip in the middle. Lastly, chamfer any edges that need to be crisp, and put a use meshsmooth with 2 iterations .
