Similar to the BufferPoints service, you need to create schema feature classes for use in the three models. For this service, you need three schema feature classes: one containing point features, one containing line features, and another containing polygon features. Create these feature classes in ToolData/Schemas.gdb.

There is one model for each of the feature types. These models are constructed using the same basic steps as described in GP Service step-by-step: Buffer points. The main difference between the models is that they use different schemas for the input variable to Buffer.

• Buffer Lines model—the Input Lines variable uses ToolData/schemas.gdb/Line as the schema.
• Buffer Points model—the Input Points variable uses ToolData/schemas.gdb/Point as the schema.
• Buffer Polygons model—the Input Polygons variable uses ToolData/schemas.gdb/Polygon as the schema.

The Buffer Lines model has one additional parameter, the End Type of the line, which is either ROUND or FLAT, as described in the Buffer tool reference. This variable was created as follows:

• In ModelBuilder, right-click Buffer, point to Make Variable > From Parameter > End Type.
• Right-click the End Type variable and check Model Parameter.

It is not required that you make a variable for End Type. End Type will default to ROUND if you do not create a variable.

The BufferFeatures toolbox is published using the same basic steps as described in GP Service step-by-step: Buffer points.
