Use FLATTEN command on your Spline, and then EXPLODE it.

 

When Spline converts to Polyline, You will get a lot of vertexes.

So You can reduce the vertexes by some lisp, but your line will be ruined.

Hi,

 

as long as the spline is just 2D you can use

  • sysvar PLINECONVERTMODE and set it to 1 >>>details<<<
  • command _SPLINEDIT
  • option convert to Polyline

 

That creates a polyline based on arcs.

_FLATTEN from my point of view is too destructive, I only use that as last option of nothing, really nothing else helped.
