PLT file viewers

This has proven to be a popular page, so I thought I would repost it at the top, with one corrected URL, and a few more applications I have run across.

The FREE Viewers are:
BIT-View: HPGL/2, RTL, TIFF, JPG
Oce Publisher: DWG, DXF, HPGL, HPGL/2, RTL, TIFF, CALS, DWF, PS, PDF, LDF.

The not-so-quite free ones:
SPLOT
View Companion Pro
RePlot
CERN HPGL Viewer
Fplot
EteCad
PentaLogix ViewMate
PloComp
CadSoftTools ABViewer
CadViewer (applet/API)
RxView

If you think you might want to convert a PLT file to a DWG or DXF file, check this out.

If you use any of these applications, let me know how it goes.
