AUTOCAD 2010 PREVIEW GUIDE
In addition to the new Convert to Polyline option in the SPLINEDIT command, you can use the updated PEDIT
command to select a Spline object and automatically convert it to a polyline. After selecting the spline and
confirming that "Yes" you really do want to convert it, you can specify the precision between 0 and 99.
Figure 42. Spline to polyline precision
To further control the accuracy when converting splines to polylines, you can use the new
PLINECONVERTMODE variable to specify the fit method. When PLINECONVERTMODE is set to 0, polylines
are created with linear segments. When it's set to 1 (the default), polylines are created with arc segments.

The DELOBJ variable has been updated to support the PEDIT and SPLINEDIT commands. If you're not familiar
with the DELOBJ variable, it was introduced as a way to control whether geometry used to create 3D objects
(profiles, paths, etc) is retained or deleted. It is typically accessed via the 3D Modeling tab of the Options dialog
box. When DELOBJ is set to 0, the option to Retain Defining Geometry, the original spline is retained in addition
to the new pline, which is created. When DELOBJ is set to any other option/value, the original spline is deleted.
