I developed one tool in arcgis using python code, in the process i used Describe(feature class) function to know the coordinate system of input feature class. I got success while compiling code, But i couldn't get how to set parameters for this function in tool(arcgis 10.0) designing.
I tried parameters as follow
Display name:input feature class Data type : coordinate system. Type : optional Direction : input.
My problem is while i'm selecting input feature class, i didn't get coordinate system of that feature class.
