“Bearing” Connection option only works when scoped to geometry entities that are perfectly concentric. After scoping the Reference and Mobile bodies, carefully check the X,Y,Z coordinates reported in the details window of the Bearing connection. They need to be exactly the same. If they are even slightly different, due perhaps to geometric tolerance issues, the Bearing will remain underdefined. This can be corrected by copying the coordinates from Reference body to Mobile body or visa-versa. This is only a valid fix if the difference in coordinate values is negligeibly small. Check results carefully.<\/p>\n","protected":false},"template":"","class_list":["post-162138","topic","type-topic","status-publish","hentry","topic-tag-2019-r3","topic-tag-coupling-and-constraints","topic-tag-mechanical","topic-tag-modeling-and-meshing","topic-tag-structural-mechanics"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
