Method used by the editor to capture Z-values.
Constant | Value | Description |
---|---|---|
esriCaptureCurrentZ | 0 | Use Current Z value. |
esriCaptureInterpolateZ | 1 | Interpolate Z value. |
esriCaptureSurfaceZ | 2 | Derive Z value from surface. |
esriCaptureCurrentZ new features are assigned a z-value based on IEditSketch2_CurrentZ.
esriCaptureInterpolateZ will initially assign NaN to the z value of the new vertex when working with the edit sketch until the sketch is finished. Just before the sketch is completed these NaN values are resolved to a definite value. At least one vertex in the sketch must have a simple z-value (non NaN) defined to successfully assign z-values using this method. The editor commands that do not interact with the edit sketch will immediatly resolve the z-value.
esriCaptureSurfaceZ requires that a surface is defined via IEditProperties4_Surface. Each new vertex is assigned the z-value taken from the defined surface.
