cjk Posted November 23, 2010 Share Posted November 23, 2010 Does anyone have a lisp routine that can create a polyline from a given area & one given x or y distance? We have a list of room areas that we must have the exact SF & fit several of these rooms into an existing floor plan. It is very tedious to change a vertex to get the SF.

nestly Posted November 23, 2010 Share Posted November 23, 2010 Not a lisp, but did you know you can create a rectangle based on area and the length of one of the sides? http://screencast.com/t/6xHqF6XX Quote Link to comment Share on other sites More sharing options...
cjk Posted November 23, 2010 Author Share Posted November 23, 2010 How about a non rectangle? Quote Link to comment Share on other sites More sharing options...
edwinprakoso Posted November 23, 2010 Share Posted November 23, 2010 Have you tried using parametric feature? You should be able to do it, but you need to be good in math Quote Link to comment Share on other sites More sharing options...
edwinprakoso Posted November 23, 2010 Share Posted November 23, 2010 (edited) I created this code for regular polygons. Please don't laugh... this is my 2nd AutoLISP code ; This LISP will create regular polygon by defining polygon area and number of sides ; Created by Edwin Prakoso ; Website: http://cad-notes.com (defun c:polyarea (/ n a apt) (setq n (getint "\nNumber of Polygon Sides: ")) (setq a (getreal "\nExpected Area: ")) (setq apt (sqrt (/ (/ a (/ (sin(/ pi n)) (cos(/ pi n)))) n))) ;calculating apothem for circumscribed polygon (setq ptloc (getpoint "\nPick Location: ")) (command "_POLYGON" n ptloc "C" apt) ) Edited November 24, 2010 by edwinprakoso Quote Link to comment Share on other sites More sharing options...
