Terrain Modeling Question

To convert in AutoCad text survey data to 3D geometry that can be sandboxed, you can try the attached lisp file I once made that might be similar to the one mentioned by TIG in the thread Kenny pointed to.
It is very simple: it takes a text entity, reads it, converts the data into a number, multiplies it with a factor you supply (in case of survey data in meters in a file in millimeters, common in my case) and draws a short line with the z coordinate set to the calculated number. Not very accurate but sometimes usable. The line xy location is derived from the text insertion point.
Usage: Unzip to a location where ACAD can find it. Type (load "txt23d") to the ACAD command line and press Enter. Type the command txt23d and Enter. Select the text objects and press Enter.
The lisp has not much error processing so save your DWG file before using it. If the texts use another decimal separator than a point, you should replace them with points before using.

Tim,
Hope that converted file is of some use to you.
