2d topo survey to 3d

Hi, I've got a 2D topographic land survey that I want to use in Civil
3D. The problem is that there are no Z coordinates on the drawing
entities - the levels are just written as TEXT entities all over the
drawing.
I thought of getting a script written that could convert each text onto
a POINT entity, but unfortunately each piece of text is not at the exact
point that it refers to - there is a cross somewhere near each text
which represents the place where the level should be.
Does anyone know if it is possible to convert this type of 2D topo
survey into an accurate 3D DXF/DWG?

Thanks, JF.

 

Thanks, that's quite useful by yes lot's of work. Unfortunately, there
are about 200,000 level items on this drawing, so I think it would take
about a month to do it that way.
Is this a common problem for Civil3D work?

 

From what I've heard, yes. In surveying, as in most things, you get what you
pay for...
