Simplify Spline
Use the Simplify
Spline tool to reduce the number of points in a spline and to increase
system performance in models with complex spline curves.
You can
also simplify splines that were created from imported models or from tools
such as Convert
Entities, Offset
Entities, Intersection
Curve, and Face
Curves.
To simplify
a spline:
In an open
sketch, select the spline in the graphics area, then click Simplify
Spline 
(Spline Tools toolbar) or Tools, Spline Tools,
Simplify Spline.
In
the dialog box, set a value for Tolerance
and click OK.
- or -
Click Smooth
to continue simplifying the spline. You can click Smooth
until only two spline points remain. The SolidWorks software:
Adjusts
the tolerance and calculates a new curve with fewer spline points. The
original spline is displayed in the graphics area along with a preview
of the smoothed curve.
Displays
the Number of spline points for
In
original and In simplified curve.
Displays
the simplified Tolerance, which
measures the intended deviation of the simplified curve from the original
curve.
Click Previous to
return through the sequence as far as the original curve.
Click OK.
