I am working in the Assembly Design app with a model imported from CATIA .In all parts of the tree the symbol of 'No identity position' appears. Only one part does not have it. The latter is the one I got fixed in CATIA model and the others had constrained connections to it, so that at the end all were 'fixed'.

What does it mean the symbol of 'No identity position'? Are all parts fixed in the model or not?
