Hinge Orientation

[Rbrgr83]

Let's say I have a hinge joint. I join the 2 parts in assembly, and as part of that definition, I set two surfaces to be Angle Offset. Is there a way to flip the convention of positive rotaion while i'm defining the placement?


For example. I've got a number of different hinges on an upper level assembly. If I want to set up a relation so that I can specify to what angle they are open (lets say 30 deg), how do I make sure they all open the same way??

Bear with the following and your question will be answered.

Datum planes have direction brown/black. (used to be red/yellow)
Axis have direction. The tag name indicates this by which end of the axis it is attached to.

The direction of an axis depends on the references used to define it. For instance if an axis is defined by two datum planes and the direction of one of the datums is flipped - the axis will flip direction. Likewise the order in which the datums are chosen will change the direction the axis points. It's a right hand rule thing.

The direction of angular dimensions can be influenced by the direction of the references and or the order in which they are chosen. Sometimes even by the point at which the referenced entity is touched.

So what you can try is to redefine the axis, one or both so they point in different directions. Or you can flip the direction of the align-angle references, one or both.

If the assembly references are such that they can't be flipped. You could add datum features that can be flipped to the parts and use them as assembly references.

Hope that helps..
