It is a great pleasure for me to greet you. I would like to know if you could help me. I have a problem with my assembly described in the attached photo. In which I have a linear bearing with a relation of concentric position on a bar. This bearing should move, previously it did. But I stop doing it and I do not know what it should be. I think I accidentally press some command and I do not know which one. It is important to be able to obtain a concentric movement through the bar. Because in this way you can project the rest of the components.
