The Smooth command is used to smooth connectors or database curves
using “C1” curve approximation.
Use the Smooth command to apply a C1 approximation to either connectors or database curves.
Select connectors, database curves, or a mixed set of both, then Edit, Smooth. Click OK to implement the smoothing immediately using the
default tolerance shown in the Fit Tolerance text field. Otherwise, uncheck the Use Default toggle to enter your own tolerance in
the Fit Tolerance text field. Click Cancel to exit the Smooth panel without saving any changes.
Depending on the grid point resolution of connectors or the zoom level of a database curve, the changes made by the Smooth command may not be immediately
obvious. When in doubt, use Edit, Curve to view the actual control point shape definition.
Tip: The Smooth command is very useful for situations in which you need to smooth out discontinuities in curves. Be aware
that you can control the degree to which a curve is smoothed by changing the tolerance used.
