sounds similar to :
You can't import to TBC from Autocad if you have the drawing open in Autocad.
I can't say I've had this issue with exporting data the data.
A thought could be that the export panel is open in TBC, and holding a lock on the CAD file?
Try closing the export panel before opening in Autocad.
Otherwise, put your process down, and add in some screen grabs to show what the sequence is.
i.e.
1. Home Tab
2. Export
3. CAD
4. DXF exporter
The select data
Enter a name for the file.
Have no to export as block

Subject: DXF files are read only
Thank you for your time responding.
You understand? I am making a .dxf from Trimble Business Center. When I open that file in AutoCad, CAD shows as a read only file. It is not read only in windows. Trimble Business Center for some reason make it a read only file. It is frustrating.
Why is Trimble Business Center making read only files is my question?
Once it is read only, I can't seem to get it to stop being read only. I have tried several things and nothing is working. I just want Trimble Business center to not make read only .dxf files.
The problem is the rover cannot separate layers with a read only .dxf file. It sees the layers, but the guys can't turn off/on layers.

If you are exporting from CAD and have that file open, and then trying to save with the same file name this could be the issue.
We use save as (and save back to 2004 dxf if possible). (depends on your data and end use).
We then give that saved file an applicable file name.

I am exporting a .dxf for the rover in TBC. For some reason it makes the file read only and the rover can't utilize the layers. I am exporting as a new .dxf file.

I'm not exactly sure what you mean by read only.
DXF is not a native format for TBC. So you can't use TBC to edit an existing DXF file. However what you can do is import a DXF file into TBC, edit the data and export it as a new DXF file.
What field software are you using?

Can someone tell me how I can make dxf files that are NOT read only?
Sometime they are and sometimes they aren't.
The field equipment can't read my files.
Please, please someone help me!
