I got a problem when I want to make a modelbulider in ArcGIS 10.
The thing is that: I have a polyline shp file with length field in attribute table (havent been calculated so they are value 0 now). Now I have no idea how can I make a function to calculate geometry in modelbuilder(I knew how to calculate manually by just right-clicking field and choose calculate geometry). I tried to serarch Calculate geometry in toolbox but there was anything.
I know I can also do this manually but my project is quite big. In this case, it would be a good idea to create complete model to process everything.
Could someone help me to solve? or if there is any other way works well.
I would be much appreciate if anyone can help me.
