PROBLEMS TO EDIT A TERRAIN MODEL

I am working with an imported Terrain Model and  I'm trying to delete some triangles in the model.

But the Terrain model is as locked.

The feature definition to Terrain model is Existing triangles but I've also tested with others.

Is not possible edit the triangulation?

Thanks.

  • I know there are specific cases where you can not edit a terrain model.  See this post communities.bentley.com/.../99819.aspx.  This is a specific case where features have been imported from a corridor.  Another situation I could think of is when a terrain model has been created by importing a DTM.  I do not believe you can edit the triangles in that case, although I may be wrong on that on.  In your case it appears the terrain model has been constructed via a series of points so I would assume so other factor is at work here.

  • I'm not sure if this is your problem, but it sounds like you need to deactivate the survey processing rules:

    Right-click on your survey project in Project Explorer “Survey” tab, select “deactivate survey processing rules”.  Otherwise, it will show up as “not an editable terrain”.  (Note: either the data is editable, or the terrain is editable.  Not both.)  

    Triangles can now be edited.  Survey data is NOT live; points cannot be added or moved and have triangles follow the changes.  

    IF RULES ARE REACTIVATED in the Project Explorer “Survey” tab, ALL TRIANGLE EDITS WILL INSTANTLY REVERT.
