Triangular Meshes

Right-click commands for the Triangular Meshes branch of the Data Tree — the branch header and its folders, and each mesh. Under each mesh are seven nodes with menus of their own: Attributes, Graph Networks, Textures, Paint Overlay Layers, Projective Images, Photogrammetric Images and Tie Points.

Source resources: IDR_DT_MESH_ITEM, IDR_DT_MESHGROUP.

Surface Generator submenu

Only shown for surfaces generated from interpretation data (see the Surface Gridding guide).

• Paste Orentation — Re-orient the gridding plane from an orientation on the clipboard (use Copy Orientation on a structural measurement first); useful for steeply dipping surfaces. Greyed out until an orientation is on the clipboard. (ID_MESH_GENERATOR_ORIENT)

• Edit Faults... — Open the fault dialog to add, remove or re-type the surface's fault definitions, then rebuild. Each fault names its own traces, so a fault trace does not have to live in a particular polyline group. See Faults & breaklines. (ID_MESH_GENERATOR_EDIT_FAULTS)

  Fault definitions belong to the 2.5D kriged grid only, so this entry is greyed out on an implicit (3D) surface — selecting it there reports "Fault definitions apply to kriged (2.5D grid) surfaces only."

The generator's own parameters — the gridding method and its settings, Auto Rebuild, and the read-only Defined Faults and Blocks counts — are in the mesh's property sheet, not on this menu. See the Surface Gridding guide and Implicit Surfaces.
