eliptical array

[michaeloureiro]

hey all,

 

this is probably more of a geometry question, but is there a way to array in an eliptical pattern?

 

thanks,

in basic AutoCAD you can retangular and polar. I am not aware of any other option. It should be possible to do what you want using LISP or VBA but I wouldn't know where to start. I would be more inclined to draw my elipse and see if MEASURE or DIVIDE works.

well, that´s how i usually do it, but it´s very time consuming.

Visit cadalyst magazine's CAD TIPS. Do a search for elliptical array. It should pull up a routine called Copy-Align (CA.LSP) written by J.D.Henman and submitted 01-Nov-2003. It's tip number 1911. Here is the author's description:

 

"Unlike the Align command, CA.LSP lets you pick both reference points on an object first, then enter the number of copies you need to align. One (1) is the default, and zero (0) aligns without copying. The pivot point is always the first pick in either case. I use this a lot with cylinder pivots in layouts because I don't have to use a separate Copy command. I also use it to array objects around elliptical profiles using centerlines as my references. You don't need to enter a quantity to do multiple copies."
