elevation data

During the import (v.in.dxf) there were WARNINGS about 3d data, which GRASS cannot accommodate.  I may have lost the elevation data for the contours then, or maybe not!  The map information comes from NTS maps from the Ministry of Natural Resources in Canada.  They are 1:50000 UTM with 10m intervals on the contours.  Hopefully, it will be possible to fix the contour information without manually entering elevation data for thousands of lines.
