Mechanism - Double Pin Connection?

Question

Hi again!I'm trying to design an automatic lid with a lifting arm attached to it. The picture will probably make it self explanatory. I want to add a strut to constrain the lifting arm so that it stays horizontal. I'm not sure how to constrain the strut though. I have tried two pin connections but it doesn't move when I drag the lid. It just locks up. I have also tried a single pin connection and then a standard Axis->Axis contraint on the second pin but I get the same problem. Could someone shine any light on which constraints I need to use to get that working as intended. Hope I have explained it clear enough, let me know if I haven't and I'll to animate what I want.

Hello LeeI thing that your problem is it not with PIn /Cylinder connections, but with definition kinematic scheme?!?I created two videos. At first (pin_conection.wmv) you can see how define constraints for your model.For the second (new kinematic scheme.wmv) shows the definition of the new kinematic scheme. I created only axis for connection - you can add new model which represents a new model through the axis.

Hello.In this case do you need use Pin connection and Cylinder connection.
