Provides access to members that define operations common to polylines and the boundaries of polygons. Note: the IPolycurve interface has been superseded byIPolycurve3. Please consider using the more recent version.
Product Availability
Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.
Description
A polycurve is a collection of many curves that form a single curve. A polycurve can be composed of single segments, connected paths, closed rings, or a combination of various curve types. The paths and segments within a polycurve do not need to be connected to each other. A polycurve may also contain a single segment or path.

![]()  | 
QueryFromPoint | Copies this curve's 'from' point to the input point. | 
![]()  | 
QueryNormal | Constructs a line normal to a curve from a point at a specified distance along the curve. | 
![]()  | 
QueryPoint | Copies to outPoint the properties of a point on the curve at a specified distance from the beginning of the curve. | 
![]()  | 
QueryPointAndDistance | Finds the point on the curve closest to inPoint, then copies that point to outPoint; optionally calculates related items. | 
![]()  |

![]()  | 
QueryToPoint | Copies the curve's 'to' point into the input point. | 
![]()  | 
ReverseOrientation | Reverses the parameterization of the curve ('from' point becomes 'to' point, first segment becomes last segment, etc). | 
![]()  | 
SetEmpty | Removes all points from this geometry. | 
![]()  | 
Smooth | Converts this curve into a smooth curve containing only Bezier curve segments. |

![]()  | 
Weed | Generalizes using a small tolerance based upon either the system units of the geometry's spatial reference, or the geometry's bounding box. |
