FPL to JXL Conversion

What are FPL files?

FPL is a front panel layout file created by front panel design software, used to draw the faceplates of electronic devices, instruments, amplifiers, and enclosures. A file of this type describes a flat panel with its outline, drilled holes, cut-outs for displays, switches, and connectors, and printed labels or scales around controls.
