I have a few tables that contain point and line features. I can group them but I want to create a boundary polygon for a database so when I need to pull them up I can use the boundary to grab all files. My thoughts were to group the line and points as needed and then run the groups through a MinimumSpanningCircleReplacer. From what I read am I correct in assuming that this tool will do just that and leave me with a polygon at the end that is a outer boundary of the grouped line and point features?

Boundary around points and lines segments

If you want a rectangle the BoundingBoxAccumulator can be used.
If you need any polygon the HullAccumulator is the best option.
@kouri1986I'm not exactly sure what you are trying to do, but you may want to also look at the BoundingBoxAccumulator.
Hi @kouri1986, I agree that the BoundingBoxAccumulator or HullAccumulator can be used to create areas surrounding the features for each group.
The MinimumSpanningCircleReplacer doesn't have the "Group By" parameter. If you need to create a minimum circular shape surrounding multiple features, consider using the Aggregator to aggregate features for each group beforehand. In addition, note that there are cases where this transformer won't create exact minimum spanning circles in FME 2015 and earlier. The issue has been fixed in FME 2016, so I recommend you to use FME 2016 if you want to create circular shapes with this transformer.
