The general approach to setting up complex simulations outlined in the previous topic involves progressively setting up the Supersequence and then the Dumps, on a Strip by Strip basis. The setup process therefore involves setting up Staged Excavations on a strip by strip basis followed by assigning the Dumps on a strip by strip basis. As a consequence of this completion of each stage of the setup leaves the operation in the completed state (i.e. after excavation setup all strips will be excavated, after assign dump set up all strips will be excavated and dumps will be complete). It is therefore necessary on completion of a particular stage to be able to restore the design file to the starting state. This is achieved by the use of simulation restore points.
The restore command is accessed via the main menu:
Terrain/Restore
The Restore command uses an Inner Surface which is a model of the topography at the desired restore stage, this is referred to as the Restore Point Surface. The Restore Point Surface must be saved by the user at the appropriate time (state). When the Restore command is run the following actions will be implemented:
•The topography will be restored to the state of the nominated Restore Point Surface
•All Material Logs will be reset. This reset zeros all Logs and removes all Log History information.
•If the command is used after a full truck shovel simulation, all simulation history is removed.
In order to use Terrain/Restore a suitable surface representing the desired state of the topography must be available. A copy of the topography can be saved at any time by using the Terrain/Restore command, which has an option to Create Terrain Restore Surface.
Important Information - Terrain Restore Surface
Terrain Restore Point Surfaces can add considerably to 3d-DigPlus file size. Consequently 3d-DigPlus does not automatically create these points. It is very important to create Terrain Restore Points at the desired states of the design process.
If you have not saved a suitable Restore Point, it may still be possible to locate a suitable surface and perform the restore manually. Most typically the desired Restore Point is the starting topography. In such cases the data file originally imported for the topography can be reimported as an independent Inner Surface, then used for Restore.
If the desired Restore Surface is a state where the design has progressed somewhat and altered the original topography, it is likely that a 3d-DigPlus file would have been saved at this state. If this is so a Restore Point Surface can be acquired with the following procedure:
1.Save the existing 3d-DigPlus file.
2.Load the 3d-DigPlus file with topography at the desired state.
3.Go File/Save As, from the Files of Type list select Grid Heights (*.bit), then select the Terrain Surface for save, give it a suitable name.
4.Open the previous 3d-DigPlus file, go File/Open, from the Files of Type list select Surface Grid (*.bit) and select the saved bit file. This file will be loaded as an Inner Surface.
5.Use this newly loaded surface as the restore point surface.
