Curve Object (Visio)

An item in a Path object that represents a consecutive sequence of rows in the Geometry section of its Path object.

Version Information

Version Added: Visio 5.0

Remarks

The default property of Curve object is Point.

If a Curve object is in a collection returned by the Paths property of a Shape object, its coordinates are expressed in the shape's parent coordinate system. If the Curve object is in a collection returned by the PathsLocal property of a Shape object, its coordinates are expressed in the shape's local coordinate system. In both cases, the coordinates are expressed in internal drawing units (inches).

A Curve object describes itself in terms of its parameter domain, which is the range [Start(),End()]. Use the Start property of a Curve object to obtain the curve's starting point and the End property of a Curve object to obtain the curve's ending point.

Use the Point method of a curve object to extrapolate a point along the curve's path. Use the PointAndDerivatives method of a Curve object to determine a point along the curve's path and, optionally, its first and second derivatives.

Use the Points property of a Curve object to obtain a stream of points that approximate the curve's path.
