Hello, this is Cassandra bringing you another blog post about a common question ArcGIS 10 users may have when learning the new editing interface in ArcMap – I certainly did!
When you start editing either a saved map document or a brand new map, ArcMap checks to see if you have any existing feature templates in the map. If no templates are found, ArcMap automatically creates them to help you get started adding features. If you have layers from several different geodatabases or folders of shapefiles in a data frame or multiple data frames in a map document, ArcMap creates templates the first time you start editing in each workspace or data frame if there are no existing templates.
However, if you later add more layers to the map, they may not appear in the Create Features window during the edit session. Take a look at the following example:
I performed some editing on the States layer, and then later added the roads layer to my map. As all of these layers are shapefiles stored in the same folder, I assumed when I started a second edit session that I would see all of the shapefiles in the Create Features window – but my roads layer is missing.
This is because once templates are created the first time you start editing, they are not added automatically after that. You need to create the templates yourself for layers subsequently added to the map. This allows you to control the creation of templates and avoid cluttering the list of templates with templates for layers that may not be used for editing.
