Just to recap; in Part 1 we imported the data. At this point the linework is 2D (doesn’t have a Z elevation). In this (Part 2) post we run a query to elevate the data. A common mistake I see a lot of users make is they don’t start a new blank DWG, they don’t select “Draw” under the Query mode, or they forget to alter properties (mapping to a data field).

So the process looks something like this:
1. Import the SHP file into Drawing 1
2. Create a new Drawing 2
3. Attach Drawing 1 to the empty/blank Drawing 2
4. Define and execute the query (making sure your query mode is Draw, and you select the correct elevation field to modify the properties)
5. Verify Map redrew the topo from Drawing 1
6. Detach Drawing 1

How do you preserve the elevations in the contours after executing the query? I ran your procedures in Autodesk Land Enabled Map 2004 and everything worked fine, yet after when I detached the drawing from the session and reopened it, the elevation values were gone. I would like to preserve the elevation values so I can label the contours. Any input would be beneficial.
