converting cst to dxf file

Hello
I have problem converting .cst file to .dxf file. And I need to design the PCB board. The staff who made the PCB board changed this .dxf to .eps again and it did not work. I think my .dxf is not right.
Can anyone help me suggest the solution to this problem?

Try to put the root of the coordinate system in the plane that you want to export.
You can use/create a working coordinate system (WCS) for this:
Select a point in the plane, then WCS->Local Coordinate System
Export it again.
Do you have a software to open the DXF files? For example many drawing software can import DXF.
With this you could see if the DXF file is right, or what you have exported.

Thanks for your reply.Yes, I can look DXF file and it shows exactly the same with my design but with different measurements. for example, I drew a line with 10mm but in DXF file, it shows 10 inches. Any idea with this?

There is sometimes a problem with inches and mm in DXF.
I don't know if DXF has an information if the Dimension is mm or inch, but I don't think so. Thus if a software works in mm it export the DXF in mm, and if an other think it is inch it inport it as inch.
Can you select on your tools the dimension when you inport the DXF, eg. a scale factor?
Or can you open the DXF scale it and then export it?
Do you use mm or inch in CST? Pherhaps you can change this?
