Howdy folks-

Our company designs piping systems in AutoCAD using 3D solids for pipe and fittings and am now working on a LISP routine to automate inserting u-bolts. I'd like to set the u-bolt size by picking the cylinder the u-bolt will straddle, but haven't been able to decipher the dxf data for 3D solid entities.

Would anyone have a piece of LISP code that can extract the radius or diameter of a 3D solid cylinder?

Thanks in advance,
