MarcoW Posted August 26, 2009 Share Posted August 26, 2009 I found this nice routine to edit my 1 - line piping... It works for as long as we draw lines, not polylines, too bad. Why doesn't it work with polylines? I get the message: Zero length line created at (13097.1724, 1164.9590, 0.0000) No changeable object selected So I figured it has to do with the object type. ; Chamfers first line to second line and leaves second line unchanged. ; In other words, does not trim second line to chamfer. ; (DEFUN C:CHAMFER2 (/ A B AN BN AE BE AN1 AN2 TN1 TN2 TN3 NS RS R C) (SETVAR "CMDECHO" 0) (SETQ B (ENTSEL "LINE TO CHAMFER: ") BN (OSNAP (CADR B) "NEAR") BE (OSNAP (CADR B) "END") A (ENTSEL "UNCHANGING LINE: ") AN (OSNAP (CADR A) "NEAR") AE (OSNAP (CADR A) "END") NS (INTERS AN AE BN BE NIL) RS (STRCAT "CHAMFER <" (RTOS (GETVAR "CHAMFERA")) ">: ") R (GETREAL RS)) (IF R (SETVAR "CHAMFERA" R) (SETQ R (GETVAR "CHAMFERA")) ) (SETQ AN1 (ANGLE NS AN) AN2 (ANGLE NS BN) C (- AN2 AN1)) (IF (> C PI) (SETQ C (- C (* 2.0 PI)))) (IF (< C (- PI)) (SETQ C (+ C (* 2.0 PI)))) (SETQ TN3 (ABS (/ (* R (COS (/ C 2.0 ))) (SIN (/ C 2.0)))) TN1 (POLAR NS AN1 TN3) TN2 (POLAR NS AN2 TN3)) (IF (MINUSP C) (COMMAND "LINE" TN1 TN2 "") (COMMAND "LINE" TN2 TN1 "") ) (COMMAND "CHANGE" (CAR B) "" TN2) (SETVAR "CMDECHO" 1) ) For the chamfer command itself works with plines. Only a hint would be okay. Quote Link to comment Share on other sites More sharing options...
