problems converting to dxf or dwg

Hi all,

I need to have some files cut by laser in metal. They require dxf or dwg files.

I tried converting my .3dm files to dxf but the curves don't come out right. After searching the forum, I came across the 3DMCurves2dxf convertor but after
downloading it and clicking on it my mac says :You can’t open the application “3dmCurves2DXF.exe” because Microsoft Windows applications are not supported on OS X.

Is there another way around this?

Thanks much!

Gunter
