I have been sent some dgn files and it would be very helpful if I could use AutoCAD Lt 2007 to open them.
Can anyone help??
Ask them to convert the files for you to DWG or DXF, if HELP in LT2007 offers no solution for it.
Or you could buy a current LT version that has that ability built in.
Or you could buy a DGN to DWG converter to do the same.
