dxf to polygons

[Andrea Giacomelli]

Hi,
I need to import some DXF files to GRASS.

With linear themes, the v.in.dxf3d does an excellent job; with
polygon themes I have problems in reconstructing the proper polygons via 
v.digit.

I can first of all "re-type" arcs from line to area; however, 
when I pass to assigning labels, the process succeeds only if the
polygon is composed by 1 or 2 arcs (otherwise v.digit says it
is not able to define a polygon).

At any rate, reconstructing the polygons manually can become very
time consuming.
I have re-checked the documentation on v.in.dxf and v.cadlabel,
and I see that there is no mentioning of polygon themes...

So: is it possible to reconstruct automatically a polygon from a DXF polyline ?

Maybe with polylines defining the arcs and text labels positioned
inside the polygons ?

I will be grateful for any hints !
