Yes, that's not too unusual that with text files you will be allowed to type in many different extensions.

For example if you run notepad, you can enter any extension that you wish, including .3dm.

But it is not recommend that you do that, because a proper .3dm file is intended to be structured differently than a text file.

So doesn't seem like a problem!

The extension is not so important - it is the contents of the file that is important, it should be a text file that contains numeric data, I think x,y,z data one point per line.

It is not unusual to have a .csv extension for a text file that contains "Comma Separated Values".
