Your solution depends on whether your points really represent contours or are samples.

If the points are contours, and are ordered well, you need a utility to create plines 
out of a set of 
points. There may be something to do this around already but it may need to be 
flexible enough to 
handle grouping by feature and type. Alternatively, it would be a fairly simple 
MapBasic program to 
run through all of your data and do the dot-to-dot work.

If you point data is samples, you need some more sophisticated software which is able 
to "thread" 
contours through your point data. This type of functionality is provided by Vertical 
Mapper.
