Mechanism & Redundancies

Hello,

I have two questions.

Is there a way to determine where is the redundancy while performing a mechanism analysis?

For example, let's say that you assemble a mechanism and check all the steps previous to the analysis (motion axis settings, dragging operations, reconnect etc.)

Now you run an analysis and when you measure the redundancies Boom! Your model has 6 redundancies!

So, in other words, what's your advice to find such redundancies? (Besides checking the connections one by one, or adding constraints in the analysis dialog box) Is there a way to find the exact connection that creates such redundancies?

The second question,

I know that redundancies are important because it ensures the quality of the analysis, but..

Is this absolutely true?

Thanks!
