How do I convert a .DTM file to be used in LDD

[feypot]

I have a .dtm file that I have to use in LDD. How can I convert it to be LDD compatible?
Thanks.

What is this .dtm file? Is this the file extension? Where did it come from? Can you get it in LandXML format, or maybe drawing entities such as 3dfaces?

From what I'm seeing it appears that a .dtm file could be an ascii format text file. You may be able to import it as you would a point file or fieldbook file.

Is the file small enough to post here so we could look at it?
