Remarks

ConstructBuffers and ConstructBuffersByDistances can generate multiple, concentric buffers around the same set of input geometries. This property is an array of distance values, specified in the units defined either by the spatial reference of the first input geometry or the Unit property. When this property is defined, each of its elements is added to the base distance specified by ConstructBuffers, or to the per-geometry distance used by ConstructBuffersByDistances. The following graphic shows the effect of specifying this property.

Example of multiple distance offsets and mixed dimension inputs when  buffering. A point and a polygon have been buffered at 7 different distances, with the results at each distance unioned together.

Generation of buffers at each distance offset counts as a separate "operation" for the purposes of progress reporting. Refer to the BufferProgress property for more details on progress reporting.
