draw an x=y? function, is there a command?

[stageleft]

is there an autocad (2000i mech) command or quick way to draw x,y functions, specifically; parabolic and cycloidal curves?

Hi,

Back in acad 12, one of the support lisp files included a fdemo file, which could accomplish what you're asking. The other thing around is writing your own lisp program or Vba macro.

Dear Stageleft;

Poking around the internet I found this .lsp program for drawing the parabolic line required when designing arched windows and doors. The file can be downloaded. Its an Italian website but the words are not too hard to figure out

I am sure you can find more if you search around long enough and probably in English too !
