Repairing a Corrupted DTM File
Sometimes a Civil Designer DTM file can be corrupted and the program will report a bucket list error. Fortunately, Civil Designer includes tools to repair the corrupted DTM.
Close the project and access the Tools › Rebuild DBase option in Terrain mode.
The following dialog will be displayed:
The next step is to browse for the corrupted DTM file.
Once the file has been selected, you will be prompted for a name of the repaired file.
The repaired file is saved as an ASCII file.
Create a new project with a blank DTM.
Import the repaired ASCII file using the File › Import YXZ option in Survey mode.
Make sure that the correct file type is selected, the preview shows the first few lines on the file.
Assign names to the columns.
Allow Civil Designer to rescale the project.
Once the file has been imported, the repaired DTM will be displayed on the screen.
If the corrupted project also included roads the DTM needs to be renamed to the same name as the original DTM. To do this close the project, and in Windows Explorer rename the old DTM and then rename the repaired DTM to the original name. The reason for this is that the road files are linked to the DTM.
Once the DTM has been renamed, the original project can be reopened. It is also good practice to make regular backups of all project data.
