Help using v.in.dxf3d

The code for v.in.dxf looks like it handles Z coordinates. The problem with
the v.in.dxf code is that it converts attributes/labels into integers because
it uses the write_att() structure from the dig_atts libraries which convert
labels into categories, which are by default integer. If a label in a dxf file
contains non-integers, it will be truncated.

(i.e. "001_bz3.cat" becomes "1"). I tried modifying v.in.dxf to handle the
text properly (it did) but when I ran v.support, it switched things back to
integers. I haven't released modifications because of this problem. I don't
know if this is part of the problem you are having, but thought I should
mention what I found out.

Dear Grass users

I have tried to use v.in.dxf3d to convert files fromdxf format in to Grass. On
autocad you can actually see the attibutes layer. However, when I try to bring it
in to dxf format, we do have some problems with it. Only the x and y
coordinates were imported to grass but not the Z value. I thought v.in.dxf3d
should be able to handle this problem. Anyone who has tried v.in.dxf3d and
succesfully imported the attributes together with it, I would like to know how yo
do it.

Thanks in advance for any help.

Cheers.
