Solid Edge currently has a little trouble determining that a dxf or dwg file can actually contain 3D data.
But you translate it like any other.
Pick Open.
Change the file type to DWG/DXF
Check any import options you may have
Select the file.
Click OK
Pick a 3D part/assembly template.
Pray.
The very first time I tried to open a 3D dwg or dxf (no solids, only wireframe) in SE the option to use a part template was available. I got an error message that SE did not have the correct filter to parse the file and dumped me out of the part environment.
Subsequent attempts did not present me with the option to choose an environment. It just opened the draft environment and presented a 2D view(as parsed by the SEACAD.INI script/file).
AFAIK SE can not handle wire data because it's only 2 1/2D
and has not been converted to true 3D data (it's a special module
within ACAD that does that).
ACAD will generate 3D data through the ACIS kernel and embed this
into the .dwg/.dxf along with any 2D data.
Upon opening such a file use the normal.dft as template which
will contain the 2D data (if any). The 3D data will be written
to a .sat file simultaneously within the same folder the original
file is in. In a second step you have to convert the .sat file
to SE
When no .sat file is created then the .dwg/.dxf does not contain
any 3D data. Have a look into the .log file created during the
conversion. At the bottom you should see something like this:
