IPolycurve3D Interface

Provides access to members that define operations common to polycurves with Zs.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Description

Provides methods allowing one to add vertices where they do not already exist (Densify), remove existing vertices based on the Douglas-Poiker algorithm (Generalize), and remove existing vertices based on a tolerance obtained from the system units of the geometry’s spatial reference or bounding box (Weed). In contrast to IPolycurve, Z values are taken into account when performing Densify, Generalize, and Weed operations.

Members

	Name	Description
	Densify3D	Converts this Polycurve into a piecewise linear approximation of itself.
	Generalize3D	Generalizes this polycurve using the Douglas-Peucker algorithm.
	Weed3D	Generalizes using a small tolerance based upon either the system units of the geometry's spatial reference, or the geometry's bounding box.
