Create Closed Mesh

This tool produces a closed mesh for a variety of functions. It creates closed mesh entities representing substrata, unsuitable materials, and variety of Design artifacts. The closed meshes created can be used for many purposes but the main function is to facilitate volumetrics. If substrata quantifications are required for a project, the substrata layered must be closed mesh entities with appropriate feature definitions designated so the Create Cut Fill volume tool can perform the analysis with their inclusion.

This tool has the capability to work with terrain models, corridors, linear templates, and mesh elements and is able to distinguish if the mesh is closed or not which enables the user to select the top or the bottom of the closed mesh for use for the top or bottom of the resultant closed mesh. If a corridor or linear template is selected it will use the top mesh of these objects.

Workflow

Element to Element method

Open cut fill DGN.
Select Model Detailing > 3D Tools > Create Closed Mesh.
Select method: Element to Element, Element to Depth, or Element to Depth using Element Boundary.
Select the element in 3D or cross section. Example, slope of the cross section as top surface element.
Select the closed mesh element. Specify to use the top of the mesh or bottom of the mesh. Example, substrata as bottom surface element and top as the parameter bottom as the mesh side.
Specify a feature definition. Example, select the feature definition top mesh.
Data point to accept.
A closed mesh is created along the side slope of the corridor.

Element to Depth method

Select Model Detailing > 3D Tools > Create Closed Mesh.
Select method: Element to Depth.
Select the mesh element in 3D or cross section. Example, the terrain model.
Type the Depth value for example.
Specify a feature definition. Example, select the feature definition top mesh.
Data point to accept.
A closed mesh 2 units depth is created.

Element to Depth using Element Boundary method

Select Model Detailing > 3D Tools > Create Closed Mesh.
Select method: Element to Depth Using Element Boundary.
Select the top surface Example, the terrain model.
Type the Depth value for example.
Select the Boundary surface element. Example the Corridor boundary.
Specify a feature definition. Example, select the feature definition Volumes_Cut.
Data point to accept.
A closed mesh 2 units depth is created within the Corridor limits.

Tables below contains description of the Create Closed Mesh Parameters.

Setting	Description
Use Fence	If checked on, this tool will consider the bounding area of the fence to provide additional control to further limit the range of the closed mesh created.
Method	Element to Element - allows the selection of terrain models, corridors, linear templates, and mesh element. It finds the common XY area between the 2 elements and uses the corresponding Z elevations from elements selected for the top and bottom to create a closed mesh. Element to Depth - allows the selection of terrain model, corridor, linear template, or a mesh element to a depth. Positive and negative values can be used. Positive is downward while negative is upward. Element to Depth using Element Boundary - allows the selection of terrain model, corridor, linear template, or a mesh element to a depth but the range of the resulting mesh can be limited to XY boundary of a terrain, mesh, corridor, and linear template.
Feature Definition	Specify the feature definition that describes the element being created.
Name	Name of created element based on the feature definition settings.
