Hi everyone,

How can I convert Spline to Polyline.

Thank you

1 way is to DXFOUT in R12 format the selcted object, and then DXFIN the file. -David

Thank you David for replay,

I did dxfout and dxfin but I still can not convert my spline to polyline.

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

Converts a selection set of splines to polylines inside the drawing. No more hoops with DXF files in R12 format.

HTH....

Ot you could use:

Code:

&#40;defun massoc &#40;key alist / x nlist&#41;
  &#40;foreach x alist
    &#40;if &#40;eq key &#40;car x&#41;&#41;
        &#40;setq nlist &#40;cons &#40;cdr x&#41; nlist&#41;&#41;&#41;&#41;
  &#40;reverse nlist&#41;&#41;

&#40;defun c&#58;spl2pol &#40;/ en ed pl&#41;

  &#40;setq en &#40;ssname &#40;ssget '&#40;&#40;0 . "SPLINE"&#41;&#41;&#41; 0&#41;
        ed &#40;entget en&#41;
        pl &#40;massoc 10 ed&#41;&#41;

  &#40;command "_.PLINE"&#41;
  &#40;foreach p pl
     &#40;command p&#41;&#41;
  &#40;command ""&#41;
  &#40;command "_.CHPROP" &#40;entlast&#41; "" "_LA" &#40;cdr &#40;assoc 8 ed&#41;&#41; ""
           "_.PEDIT" &#40;entlast&#41; "_Spline" "_X"&#41;
  &#40;entdel en&#41;
  &#40;redraw &#40;entlast&#41;&#41;

&#40;prin1&#41;&#41;

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.

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.
