Validating 3D Source DataValidating 3D Source DataUse the Validate 3D Data command before you create the site model, to check the 3D source data for errors. Even if a site model already exists, the source data can be checked. If problems occur due to erroneous site model source data, error alerts are automatically displayed. A site model with errors can still be created; however, results may not be as expected.
The following problems can generate errors:
● Duplicate 3D data points or polygons
● 3D data points that are coincident or vertically placed
● Crossing contours (3D polygons) in the 3D source data
To validate 3D source data:
1. Select the source data (3D loci, 3D polygons, or stake objects) to be checked.
2. Select the Validate 3D Data command from the appropriate menu:
● Architect workspace: AEC > Terrain >Validate 3D Data
● Landmark workspace: Landmark > Validate 3D Data
3. If the source data are valid, a dialog box states that no problems were found. Proceed with creating the site model as described in Creating the Site Model.
4. If there are errors in the source data, the Problems with Site Model Source Data dialog box opens.
Problems encountered are listed, and some conditions have an associated button for correcting each error by modifying or deleting the erroneous data.
If a site model already exists, the problem data can be viewed by selecting the site model and selecting Modify > Edit Site Model, or right-clicking (Windows) or Ctrl-clicking (Mac) and selecting Edit Site Model Source Data from the context menu. Problem data conditions are highlighted and annotated.
5. When problem correction is complete, click Close.
Select Validate 3D Data again to ensure that the errors have been corrected.
