How to offset bpoly with varying distances
« on: July 08, 2015, 03:00:18 AM »
Anyone know how to do this?  I need all sides equal except the one.  Preferably the one would all be on the side I designate.

(defun c:tt() (vl-load-com)
  (while (setq pt (getpoint "\n插入点"))
  (command "-boundary" pt "" )
  (setq en (entlast))
  (entmakex (list (cons 0 "TEXT")         
                    (cons 10 pt)
                    (cons 1 (rtos (vla-get-Area  (vlax-ename->vla-object en)) 2 2))
                    (cons 40 5))
       )
  (entdel en)

Na...getting close myself though. It's tough but will figure it out.

Best I came up with was code using boundaries and offsets.  Only works with straight edged offsets like the ones in your pic but would be harder for curves/arcs.

Just as exercise...
Explode polyline, offset each line/arc, create boundary.
