Thank you for your answer, I wondering did I something wrong while doing splitting operations, without split there is none sweepable body but now I have few bodies but still something feels wrong because when I checked sweepable bodies I saw one body is ok for a sweep but its mirror simetric(splitted with the same way) its not sweepable, I have few examples like that and you can see one in the picture. The body in the left is sweepable but body in the right its not, they only have slightly different wides and thats all. What possibly went wrong here? Do you have any tip for splitting? Since I am not used to do this kind of splitting operations of mesh I might did something wrong.
