The tool output is not saved in a model when the output name is constructed from an inline model variable of type Workspace and is run from the toolbox.
Ran the model as a tool from tbx in ArcGIS build 10.3_4271 and received the desired output; Added a screenshot of the output to the data location.
解决办法
A) Break up the model so one model ends with the Project tool and the other model begins with the subsequent tool in the workflow.ORB) Convert the affected sequence to Python script.
