Description

Creates a MultiPatch or Polyline from a base geometry by extruding the base geometry along an axis defined by the input Line. The base Z value of the geometry is uniformly set to the Z value of the Along Line's FromPoint and top Z value is uniformly set to the Z value of the Along Line's ToPoint. The top geometry is also shifted in the X and Y directions by an offset defined by the X and Y change of the Along Line between From and To Points. The resulting extrusion is always parallel to the XY-plane on both the base and top. The input line should be ZAware and ZSimple.

Remarks

All non-linear segments are treated as linear segments when extrusion is performed. Only Polylines, Polygons, Envelopes, Points, and Multipoints are allowed as input geometries. Polylines, Polygons, and Envelopes will output MultiPatches while Points and Multipoints will output Polylines.
