Modular Synth Panels

Hey all,

I am designing a Buchla format panel for JH's LVCOs for somebody, but have become stalled (very annoying, I hate keeping people waiting and have kept this fellow waiting for a LONG time).  I need just a couple of things - .hpgl or .plt items for triangle and sine waves, and some idea on size layout for the laternating lines and dots B&A used for pot ticks EG on the "mod index" and "timbre" knobs on the 259 module - alternatively does anyone have a small skirted rogan knob they can measure the diameter of for me?  I'll stick the panel as is so far up in the files section in a minute

Thanks!
