So bug report?... My $length calcs are messed up too, I had to make a field and use ArcGIS to get the lengths and then go back to QGIS and use the field value for my script. I tried turning off the geoid in the settings and set the measurements to use planametric but it didn't work. I really don't like QGIS changing my CRS's, and so far keeping me locked out of making custom transformations using my own GSB files. In the past I had to make my own prj's to get certain surveys to translate into NAD83 properly. Well anyway, I am going to muddle along for now hopefully a solution presents itself. Thanks for the reply; TYler
