how to draw elbow of a pipe using fillet.

[RobDraw]

I have a simple lisp that offsets a line or an arc in both directions to a given defined width. It does require you know what radius to draw the arc centerline, though. It was made for ductwork but could be used for piping just as easily.

would you mind sharing that with me Rob?

I do 3D but i got a mate who would find that very useful i'm sure.

Sengna - the larger radius of 18 you have correct, the inside radius should be 6 and not 12, 12 is the center line radius so you would subtract 6 from 12 = 6.

 

rkent- I got you, thank you

Mike you might want to take a look at these lisps by Lee Mac, as they would likely prove helpful to your friend,

or just about anybody else, for that matter.
