SketchUp can't create tiny edges < 1/1000" long, because it regards their vertex point as being coincident and so it skips making them

Is there any method to glue/snap/stitch close vertices of the model?

I have used "Play it again" plugin to clone some component with scale+move transformation. Two components, used as seed and transformation sample, are aligned with snapping manually. Cloned components are snapped too perfectly until some iteration. Then some vertices are not snapped to the close existing ones. I think that SU do not form the faces due to their tiny dimensions so holes and ovelapped faces created.

I've tried to scale the model 1000-10000 times but no luck.
