thank you

may be I couln't expain the problem well.
I need to have centroid points of polygons and create a new point map from them.

v.type still gives a boundary map

I think v.type is ok. You should use input and outpu arguments:

v.type input=map_with_polygons output=map_with_points type=centroid,point

Have you considered using v.extract to extract points from
v.type's output? Or v.edit to delete boundaries?
