Description

Determines if the TIN feature can be rotated without creating a conflict.

The TIN feature is defined by the passed seed . If the seed is a triangle the feature is a polygon whose area is represented by the set of contiguous triangles with the same tag value. If the seed is an edge the feature is a polyline comprised of all unambiguously connected edges with the same tag value or edge type. The ITinFeatureSeed.UseTagValue property is used to determine whether the edge seed is defined by its tag or edge type.

The TIN feature is rotated relative to the specified origin point.

The rotation angle is given in degrees. Positive values rotate clockwise, negative values counter-clockwise.

A conflict results if any TIN features are within the specified spacing of the proposed geometry. This includes distance to feature edges as well as nodes.

The ITinFeatureEdit.ElementsIgnoredInConflictTest setting determines what, if any, TIN elements are excluded from the conflict test.
