Pro/ENGINEER is long discontinued and replaced by newer Creo Elements/Pro software, however the conversion of .sec (Sketch) to .dxf (2D CAD) format was perhaps possible in the original software. As far as we know, no 3rd party software can handle this type of .sec files, so the original program remains the only viable choice.

Convert from sec file
to dxf file
The table with program actions contains information about what each program is capable of doing with their files. This may be a good pointer for further searches for certain file conversions and help you find the converter you are looking for if our search result is insufficient for you. However, it is far from perfect and may sometimes show results which are not really usable because of the nature of the software handles the files. So a conversion that appears as possible, just because of matched actions, may in fact not be possible.
