Adding boundaries to 3D surfaces is an excellent way to control which parts of the surface is dis-played in both 3D but also on profile views. This command helps speed up and automates the adding of boundaries to strata surfaces.

Command: HBSI_CreateBoundary

From the OpenGround Cloud ribbon Interpretation Panel press the Boundary icon, to display the Interpretation Boundary dialog.

• Band by: The set of strata surfaces to work on. From the grid select the appropriate stratum to add the boundaries.
• Boundary Type: Pick the type of surface boundary to create, the options are:
  • Outer: Defines the outer boundary of the surface; all triangles inside it are visible and all tri-angles that are outside it, are invisible.
  • Show: Displays all triangles inside the boundary; you can use it to create visible areas within hide boundaries.
  • Hide: Masks areas of the triangulation, and therefore the stratum is not visible in the area.
  • Data Clip: Creates a surface boundary limited by a polygon object from the drawing, such as 2D and 3D polylines, feature lines, survey figures, parcels, and circles.
• Select: Picks an existing polyline from the drawing to use as the boundary. Boundaries will be added to the selected strata top and base surfaces.
• Draw: Specify the start point of the boundary and click subsequent points defining the extents of the boundary, Undo and Close options can be used. The new boundary will be added to both the top and base surfaces for the selected strata.
  • Staying within the Interpretation Boundary dialog new boundaries can quickly be added any of the strata surfaces.
• Close: To close the dialog and finish the command.
