Subject: RE: [ModularSynthPanels] How to create HPGL graphics for FPD

You need a program, CAD mostly, that will export into an HPGL .plt file.
This is a graphics language developed by HP to drive their pen plotters. It
is a vector based language if memory serves. The files (used to be anyway)
an ASCII file with the vector information imbedded in it to tell the little
pens how to move in X_Y space. It was literally a list of commands like,
(can't remember exactly so take this with a grain of salt).

PU
MOVE 112, 159
PD
MOVE 105, 100

PU is pen up, PD is pen down, etc.

It's this type of language which will drive the engraving machine and other
tools drilling, milling, engraving, etc. your panel (at least that is what I
think happens...)


The easiest way to do it is to get an inexpensive (free?) 2D drawing program
(not paint, but a vector graphics program, CAD type is good) which will save
to a .plt file. You will have to make sure your elements can be translated
into vector description and choose the appropriate "pen" settings for all
the elements, like text, to show up.

Another way is to use FrontDesigner by ABACOM (www.abacom-online.de) and
available from places like Saelig. It is made to design front panels and if
you choose an "engraving pen" it will output your objects, including text,
to a .plt file which you can import into the Schafer/Panel Express program,
Front Panel Designer.

Subject: [ModularSynthPanels] How to create HPGL graphics for FPD

I've always wanted to use the HPGL import in FPD. Unfortunately I
know very little about HPGL or .PLT files (aside from what Wikipedia,
etc. say).

My wish is that someone can tell me in idiot terms how to do this. I
am using Windows XP. What free program should I use to create/export
this file type? I tried installing an HP plotter driver and saving to
file instead of a printer. I could create the files but they don't
show up in FPD or maybe they are so tiny I can't see them?

Full details, step by step, good search words, anything would be
helpful at this point.

Thanks,
p.
