Hi A lot of my drawings are huge and I want to utilize the TREEDEPTH command. From what people have been telling me it's very useful for large 3d drawings. Orbiting is faster when the setting is changed. The default value is 3020 but I want it to go to -3020 everytime. Is there a easyway to set this everytime I start AutoCAD?...or would it be wise not to set it? I am not to familar with the TREEDEPTH command Thanks 8)
