Simulates the ArcSDE conversion on a feature by performing ArcSDE translation, scaling, and coordinate snapping. Also removes duplicate vertices resulting from snapping multiple formerly separate vertices to the same grid point. These coordinates will also be recorded in a list attribute.
If the feature was an aggregate feature, the ArcSDE conversion is executed individually on each geometry in the aggregate feature.
Input Ports
Input
This transformer accepts features whose geometry is consistent with the ArcSDE format.
Output Ports
Snapped
Features with the ArcSDE conversion are output through this port.
Parameters
Minimum X
The false origin for x-values. It corresponds to the Feature Class Domain’s Min X property in ArcGIS.
Minimum Y
The false origin for y-values. It corresponds to the Feature Class Domain’s Min Y property in ArcGIS.
Scale
A scale factor to convert to integers for x- and y-values. It corresponds to the inverse of the XY Resolution Feature Class property in ArcGIS. Together with Minumum X and Minimum Y and Spatial reference precision, this is used to calculate the domain of the spatial reference.
Minimum Z (if 3D)
The false origin for z-values. It corresponds to the Feature Class Domain’s Min Z property in ArcGIS.
Z Scale (if 3D)
A scale factor to convert to integers for z-values. It corresponds to the inverse of the Z Resolution Feature Class property in ArcGIS.
Output as integer coordinates
Select to view output as either the underlying integer ArcSDE grid or the original plane coordinates
Spatial reference precision
The precision the coordinates are stored in. Feature Classes created after ArcGIS 9.2 will all be high precision (53-bit storage). Those created before can be low-precision (31-bit storage).
Usage Notes
The ArcSDE simulation is executed only when all coordinates of the geometry are within the valid range defined by the ArcSDE format. Otherwise, the conversion is cancelled and the error attribute ‘_ArcSDE_Error’ is added to the feature. Currently, the only value of the error attribute is ‘out of bounds’ which occurs when a geometry contains a coordinate that lays outside the calculated domain.
Note that illegal geometries, such as areas with dangles, will not be checked for validity on the ArcSDE format.
Arcs and ellipses passed through the ArcSDEGridSnapper will be stroked into lines; this matches the behavior of the ArcSDE writer, which does not support the storage of these types of geometries.
Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click 
beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
