Hi all.

I have just finished my first GSSL comp and wanting to make a couple more.
I have done my first through Front Panel Express using the file kindly shared here.

A big thank you to the guys at NRG.

Now I'm on my second and wanting to impliment the sidechain thrust being offered here

So I will need to modify the front panel layout to accommodate the new Sidechain features. To modify this I will need a HPGL file of this to import to Front Panel Design. I do not have CAD can anybody do this or can suggest alternate method.

CorelDraw is capable of outputting HPGL. I seem to remember having to use an older version to be compatible with FrontPanelDesigner.
