Problems with UV editing

[Anonymous]

Hello,

I combined two models into one, but still in the UV map they are still separated.
How I can combine it, that the broad white line turn into a blue one?
In the pictures you can see that the UVs are overlaped.

Combining two meshes is just putting two balls of clay from two boxes to one. You also need to weld/merge vertices/edges, and then only you will be able sew uv-shells. The thick white line is uv border, which you will need to select and in uvEditor go Cut/Sew>Sew (Shift+S) - then it will turn into blue.
