David Bethel Posted June 3, 2004 Share Posted June 3, 2004 1 way is to DXFOUT in R12 format the selcted object, and then DXFIN the file. -David Quote Link to comment Share on other sites More sharing options...
Guest Beadin Sabovic Posted June 3, 2004 Share Posted June 3, 2004 Thank you David for replay, I did dxfout and dxfin but I still can not convert my spline to polyline. Quote Link to comment Share on other sites More sharing options...
tlyall Posted June 3, 2004 Share Posted June 3, 2004 QUOTE FROM THE DOTSOFT FAQ The new SPLINE objects introduced in R13 are nice, but there are limits on what you can do with them. So conversion to a polyline is necessary. Carefully erase all the geometry except for the splines, then save the drawing in R12 DWG (A2K users use R12 DXF) format. Then open the original drawing, erase the splines and insert the R12 file. The spline will now have become polylines. If the splines had differing elevations on the vertices, the resulting polyline will be a 3D polyline. Or you could try this link and scroll down til you see the program with this text description http://www.dotsoft.com/freestuff.htm Converts a selection set of splines to polylines inside the drawing. No more hoops with DXF files in R12 format. HTH.... Quote Link to comment Share on other sites More sharing options...
David Bethel Posted June 3, 2004 Share Posted June 3, 2004 Ot you could use: (defun massoc (key alist / x nlist) (foreach x alist (if (eq key (car x)) (setq nlist (cons (cdr x) nlist)))) (reverse nlist)) (defun c:spl2pol (/ en ed pl) (setq en (ssname (ssget '((0 . "SPLINE"))) 0) ed (entget en) pl (massoc 10 ed)) (command "_.PLINE") (foreach p pl (command p)) (command "") (command "_.CHPROP" (entlast) "" "_LA" (cdr (assoc 8 ed)) "" "_.PEDIT" (entlast) "_Spline" "_X") (entdel en) (redraw (entlast)) (prin1)) -David Quote Link to comment Share on other sites More sharing options...

BEKA Posted February 1, 2005 Share Posted February 1, 2005 Hi, I apology that I am late. I downloaded SPL2PL.VLX My question is: What should I do with file SPL2PL.VLX. Where to place this file. Thank you very much. Quote Link to comment Share on other sites More sharing options...
giskumar Posted January 13, 2011 Share Posted January 13, 2011 Hi, You just type the upload command in autocad command prompt. browse the sp2pl.vlx, hit load and close. Then type "spl2pl" command to run this command. Thanks, Kumar. Quote Link to comment Share on other sites More sharing options...

cncpatriot Posted June 26, 2013 Share Posted June 26, 2013 You can try out the new SPLINECAM app in Autodesk AppStore or download it from autocam2d.com/download link. It converts splines to polylines/polyarcs with optimal number of vertices and smoothness. regards cncpatriot Thank you David for replay, I did dxfout and dxfin but I still can not convert my spline to polyline.

JD Mather Posted June 26, 2013 Share Posted June 26, 2013 You can try out the new SPLINECAM app .... In general, I think it is OK to post commercial solutions when a current question is asked, but I do not think it is proper to search and drag up old posts for the purpose of making advertisment of new products. (especially when you do it in multiple (very old) threads) Quote Link to comment Share on other sites More sharing options...
