Having completed the set up of the automated excavation and dump sequencing, first step in setting up a full simulation is to set up Trucks and Excavators. The Truck and Excavator models allow for the machine capacity is, speeds and capacity and speed variation. Once initial set up is complete parameters can be calibrated in fine tuned. When a particular Truck or Excavator model is complete and calibrated it can be saved to file and used in future 3d-DigPlus sessions.
