I have a point feature class where I record projects' (clients) locations and several other attributes. So far I have been using it to record just one location per project. However, in some instances a project may have multiple locations, which I would like to start including. Some features would have only one point and others would have multiple points. Is it possible to convert my existing point feature class to a multipoint type? I tried through Properties of the feature class in ArcCatalog, but it seems that the Type can not changed (it is grayed out). I use ArcGIS Basic 10.3.
Thanks for any help.
