How to Adjust a Mesh from Survey Data That Is Too High?

Issue Description

You have created a mesh from a TXT or XYZ file, and it appears with an excessive thickness or is positioned too high above your project. This issue can occur due to incorrect settings during import or inherent data discrepancies.

Solution

The problem often arises from incorrect height settings relative to the project origin or discrepancies in the data itself. Here are steps to resolve this issue:

1. Adjust Height to Project Origin
   • Ensure the correct reference level is set during import. This is the height of the mesh's reference plane relative to the project origin (0;0).                                                               
   • You can also adjust this value later in the mesh settings.
2. Adjust Mesh Thickness
   • If the mesh appears too thick, adjusting its height in the mesh settings might help.
3. Adjust Z-Values in the TXT File
   • If the mesh is too high or too low relative to its own reference plane, manually adjusting the height values can help.                                                                                                               
   • Open the TXT file in Excel and adjust the values in the C column (Z-axis) by subtracting the desired difference in a separate column.
   • Replace the original values with the adjusted ones (using Paste Special Values) and re-import the file into your project.
