Hi guys! I've searched in this forum and read many discussions but didn't find a solution to my problem: I'm trying to assembly an earthquake simulator (simple model) that's made of 23 actuators (all equal) a wall and a shacking table; when I try to attach the actuators to the shacking table using the mates in assembly I got errors. The actuator is a flexible sub-assembly with two universal joints; I thought that those joints would adjust their position when I mate the actuator to the table also if they aren't alligned.. Isn't it? I'm sorry if this is a silly question but I'm pretty new with SW.
