I have come to a bump in my model. I would like to be able to trim a polyline to a specific length (metres), which is possible manually using the Trim to Length function available from the Editor toolbar. I can not however get this included into my model, so that it can be automated. I am aware that Modelbuilder is for geoprocessing tools, but is there some way I can add this function into my model, possibly as a script. Any help is greatly appreciated!
