plt to dwg conversion covers the export of 2D CAD plotter documents to DWG format, or the recovery of previously exported files back to the original.
While some kind of export or recovery this way is possible (geometry), you will never be able to 100% recover the original and have to remake it again once the core of the plotter file is translated to vectors. This is mainly because .plt files do not contain full information about the individual original entities.
Various vector graphics or CAD tools should be able to help you with this, but their capacity to read and translate .plt files may wary greatly.
