Description
These specific input features require attention. This often occurs when features are positioned outside the current XY Domain environment. The XY Domain environment sets the allowable coordinate range for x,y coordinates. If a feature falls outside this range, it cannot be added to the output. In addition, with some tools such as Append, which have a target dataset, if the features of the input fall outside the XY Domain of the target, they also will not be added. Similarly, the M Domain and Z Domain limit the coordinate range for m- and z-coordinates.
Solution
Check the XY Domain, M Domain, and Z Domain environments, and reset them to Same as Input' if they are too restrictive for your inputs. When using a tool like Append, check the coordinate system of the target dataset, and if unknown, define a coordinate system for the feature class. Also, consider creating a new feature class with a broader x,y domain if the current x,y domain is too restrictive.
