Hello, I have contours in AutoCAD Civil 3D. I want to convert them to dtm file format. I have a program from ADAMTech called 3DM Analyst that will only take dtm format. Is this possible?
Is the program looking for a file with the extension .dtm? If so, then I believe that is a microstation file format (not positive though). If that's the case, then C3D can't create that for you that I'm aware of.
A file extension of DTM can does not guarantee it's contents will be what the application is expecting. For example before you mentioned this I was aware of at least two other applications that create/read two separate .DTM formats and there are likely several others.
Do you have an example .DTM file created by the application you mentioned?
