How can I get rid of free edges 1

[ITsSB]

I'm new to femap and I'm modelling a pedestrian steel crossing all as plates. I have tried "stitch" and "NonManifold Add" and I couldn't get rid of the free edges. All surfaces have consistent mesh and nodes along their connection, but I couldn't figure out what the problem is.

This may be a slightly rude thing to ask, but, have you checked the model for coincident nodes ?

Ha! That's exactly what happened! Thank you. I don't know femap but I thought overlapping nodes will be automatically merged during analysis. Thanks again.

The first mode was an indicator the something was loose in the model. Good that it worked.
