Is there anyway to convert a spline line into a simple line or a polyline? Spline lines are extremely dificult to manage, and create a sort of problems that are easily solved if it is a polyline

 
thx

the "flatten" command from express tools can change spline into polyline .. ;)

thx a lot ;)  but sometimes it destroys or deletes some of the polylines. Is there a way to fix this ??

The flatten command is the only way I know of. There is an option not to delete lines, so this may solve the problem you were experiencing!

Command:

Flatten
:remove hidden lines? <No>

I don't tend to use splines, although they can be useful!

Export drawing to .DXF format and open the .DXF file .

This should give you the splines converted into lines

Go to Cadalyst site, search spline in the "get the code" or hot tips area.  There are lisp routines for conversion.
