[edit] Measuring, not a drawing instrument?!

Is it correct to say (or write) that a planimeter is a drawing instrument, while no one can draw with a planimeter? It is a measuring instrument, is it not?! — Nol Aders 23:41, 17 December 2005 (UTC)

Perhaps, while it cannot draw, it aids in the tasks of technical drawing? Melchoir 13:48, 5 January 2006 (UTC)

[edit] Green

The application of Green's theorem lacks two things. a) It doesn't say whether it is a linear or a polar planimeter. b) The result is not relevant. Integration of (-y,x).(dx,dy) is not what the planimeter does!Nijdam 15:47, 2 July 2007 (UTC)
