Hello everyone,
I am using Creo 9.0.0.0, and I am trying to define a slider connection for a piston and cylinder to perform its mechanism. I used to do that several times before and it worked. But this time once I define the rotation it is telling me "Connection definition is incomplete". as shown in the figure.
I have defined two assemblies, the first one which is the moving parts including the cylinder. The second assembly is the fixed parts including the piston.
I am not sure why it is not working with me.
Without seeing the definition of the "axis alignment" for the joint, I am assuming that it is the centre axis of the piston.
Then the plane you are choosing for fixing the "rotation" is perpendicular to the axis of motion - so it does not restrict any rotation about this axis.
I'd expect a pair of planes highlighted in orange for the "rotation" definition in a slider joint:
Your approach is correct. However, the planes will restrict the rotation, but it will allow a motion in one axis:
If you are wanting rotation and extension, you need to use a cylinder constraint.
The slider constraint will not allow for rotation. By picking planes perpendicular to the axis for Rotation, you have created a bad connection. The rotation constraint for a slider needs to be perpendicular to the axis to control rotation.
Missed that typo earlier and am now outside the edit time window. It should have been:
The slider constraint will not allow for rotation. By picking planes perpendicular to the axis for Rotation, you have created a bad connection. The rotation constraint for a slider should be parallel to the axis to control rotation.
