Reduces the number of edit points for a curve.
Curve data can be manually created or can be read in from foreign data.
Manually created curve data usually contains a limited number of control points.
Foreign data may come from a digitized set of control points, which could contain a large amount of points.
Simplify curve is a tool that allows you to define a tolerance to reduce the number of edit points and control vertices.
The command works differently depending on the type of curve. For edit point based curves, once you reduce the number of edit points to two, the command reduces the control poles. Control polygon based curves only have two edit points, so the command reduces the control poles.
Right-click on a curve and select Simplify to access its dialog box; for more information, refer to the Simplify Curve dialog box topic:
