Does this mean anything to anyone? Is this some kind of standard vector graphic format?
The code is used in our Graphics program to generate shapes, but it gets very tedious to do manually, so I'm hoping there is some way of generating it from a CAD drawing or something?
BTW, M = Move L= Line H = Horizontal Line V = Vertical Line C = Cubic Curve .. Z = Close

Last time I had to do something like that I used inkscape and perl.
draw in inkscape, save as SVG, mangle in
perl/python/your-favourite-scripting-language
I needed a non-rectangular windows border in Java, which you do by
using drawto/lineto/moveto type commands.
Poking around the SVG I recognised that these commands were all there,
a bit of munging with perl and voila!

I am (vaguely) reminded of a HP plotter format. I'm surprised that
there isn't a 'pen-up/pen-down' command in there, although I may be
wrong, it's been a very long time since I wrote and code (GWBASIC) to
drive a plotter.

if you export a path from gimp, it comes out in a format a bit more
reminiscent of this. its what i parse at the moment (just M commands) to
make my drilling script for the modela.

ooh, I have gimp here somewhere I'll give it a go.
I must do a demo of the Niagara software at a meeting one night - I'm sure you guys would have all sorts of uses for it - and blow my mind with what can be done with it.

Not export _to_ path. Click on the path tool and draw a path. Then in the
"Paths" list (probably one of the tabs next to your layer list) right click
on the current path (which got automatically created when you started using
the path tool) and save or export it (can't remember the terminology right
now). It doesn't give any indication that the saved path will be SVG, but
it will be.

inkscape is looking promising, it has an XML editor that will show me each path and the code for it.... however it does every segment as a separate path, I guess there is a join option here somewhere so that I can turn a heap of segments in to a single path?
Found it, the old combine button (or ctrl+L) makes it in to a single path.
Looks like I can now draw something in AutoCAD, export it to a DXF, import to Inkscape, combine to a single path, view the XML, copy and paste in to the Niagara XML file - all sounds so easy!

it appears inkscape won't join the segments in to one singular fluid path, it jumbles up the order with a heap of move commands in between - which screws things up when the graphics package does the 'fill' at the end, as I end up with lots of little closed segments rather than one big one.
maybe its a rounding error? can I set it to snap segments together if they are within say 0.01 of each other? rather than checking them to 5 decimal places?

It may be best just to export a dxf file and directly process it contents in a small converter program.
In Acad you would need to use the poly line command to create the outline.
Somewhere at home I have a book on the DXF format.
Years ago I was creating PCB designs in it and we then ran a basic program to produce Gerber files.
The DXF format has got a bit more complex since then but not unusable.
Another option that will work very well is setup an old plotter driver. Use save to file.
The old hp and huston plotters code was fairly easy to parse. But the vectors may then need reordering.

yeah hoping to do a bit more experimenting tonight.
I have found that if I draw something in Inkscape it works properly (the XML file contains a single path with no excess moves, which I can cut and paste straight in to Niagara). It just doesn't handle imported paths from AutoCAD well yet - no doubt there will be a function there somewhere to auto-join and re-order which would work.
Will be interesting to see if Illustrator handles it any better.
