Exporting Dxf

[Adalberto da Silva]

I'm trying to export a contour map from Grass to Autocad.

	I made a contour map with r.contour, transformed the binary vector to
ascii and export to dxf with v.out.dxf. Everything works well but the
resulting polylines have elevation set to zero.

	Is there any procedure to obtain a dxf file with contoured polylines
*and* their associated values of elevation?

	Thanks,
