arcgis desktop - Transfer geometry of a feature class into a table

I have a table that has a field that matches a field in a feature class. the table has M records for 1 row in the feature class. I would like each row in the table to have the geometry of the feature class. This would result in stacked geometries with different attributes.

If this were a 1:1 relationship, I would join the table to the FC and then export for the result I want. if I join the FC to the table the attributes line up, but there is no geometry included in the table.

Any Ideas on a tool or workflow for this?

I am working with 10.3 standard.

Answer

• Transfer coordinates of polygon centroids into table.


• Create XY events from relevant columns


• Buffer points to get M wrong shape polygons:

Run this field calculator expression on field Shape:

mxd = arcpy.mapping.MapDocument("CURRENT")

LR=arcpy.mapping.ListLayers(mxd)[0]
def getShape(id):
 with arcpy.da.SearchCursor (LR,["ID","Shape@"],'"ID" ='+str(id)) as cursor:
  for i,shp in cursor:  break
 return shp

getShape( !ID! )

To import correct shapes:

In the picture above "table" polygons labelled by one of their attribute. NOTE: tested on shapefiles with common field ID of integer type. Query in search cursor will change if used on FGDB or different field type.
