Does anyone have a program or makro for AutoCAD for sizing a rotary, and
drawing the troichoid,rotor, and phasing gear? How do you do the double

I have a QBASIC program that draws the the housing (tip path) and
animates a roughly drawn rotor. You can change the radial distance to
the tips, and vary the eccentricity in the body of the program. The
resulting shapes will give you input on what ratios of radius to
eccentricity that are practical. Vance vjaqua@earthlink.net
