public interface IConstructMultipoint
Provides access to members that construct multiple points using other geometries and values.
Constructs a Multipoint according to various properties of an input geometry or relations between input geometries. Useful in finding the points corresponding to properties that are not satisfied by a single output Point.

void constructTangent(ICurve inCurve, IPoint p) throws IOException, AutomationException
Creates a Multipoint consisting of all points along the input Segment that are Tangent to the input Point.
Input must consist of a single segment and not polycurves.

IOException
- If there are interop problems.
AutomationException
- If the ArcObject component throws an exception.void constructDivideEqual(ICurve inCurve, int numInnerPoints) throws IOException, AutomationException
Constructs a Multipoint consisting of the From point of the input Curve, n inner points equally spaced over the length of the curve, and the To point of the curve.
The number of points in the constructed multipoint is equal to the input numPoints plus the 2 endpoints.

IOException
- If there are interop problems.
AutomationException
- If the ArcObject component throws an exception.void constructDivideLength(ICurve inCurve, double separationDistance) throws IOException, AutomationException
Constructs a Multipoint consisting of the endpoints of the Curve and the points along the length of the curve spaced a given distance apart from each other starting at the curve's From point and ending at the To point.
If the final inner point is too close to the To point, that inner point is not included in the constructed multipoint.

AutomationException
- If the ArcObject component throws an exception.void constructArcPoints(ICircularArc a) throws IOException, AutomationException
Constructs a Multipoint consisting of four points (In that order): The Circular arc's From point, To point, Center point and the point of intersection between the tangents at the From and To points.

Constructs a Multipoint containing the points of intersection and tangency between two input geometries. The input geometries can be extended by any of the esriSegmentExtension methods. Optionally, the construction method also returns the relative position and tangency of the intersection point along each curve.
