3D Manager

The 3D Manager window displays all layers in the currently open 3D View in a tree structure. Any layer added to the view appears in the 3D Manager list.

Use the 3D Manager to:

• Edit raster, vector, and 3D layers

• Rename or remove layers

• Adjust appearance, transparency, and visibility of layers in the 3D view

3D Manager Layers

Layers in the 3D Manager are organized into two main groupings based on data type:

Planes & Surfaces: This grouping includes horizontal and vertical planes, as well as relief surfaces planes that have a defined elevation.

Raster datasets (grids) can:

• Display on a plane

  • Plan grids display horizontally

  • Section grids display vertically

• Define the surface of a plane (relief surface)

2D vector datasets (XY only, no elevation) can be displayed on a plane or relief surface.

3D Objects : This grouping includes datasets with true 3D coordinates, such as:

• Voxels

• Geostrings

• Geosurfaces

• 3D symbols

• Drillholes

Imported 3D datasets from other software (e.g., 3D SHP, LYR, DXF, Datamine, GOCAD, Gemcom, Micromine, Minesight, Surpac, Vulcan) typically appear here.

Displaying Layers in the 3D View

To add data to a 3D view:

• Drag and drop one or more map groups (from plan or section oriented maps) from the Map Manager into the 3D Viewer.

When content is added:

1. The new plane is named after the source map’s data view.

2. If multiple planes exist, Oasis montaj checks for an existing plane with the same name as the data view:

   • If found, content is added to that plane

   • If not, a new plane is created

3. If the existing plane and source orientation are identical and a group with the same name already exists in the 3D View, the group is added with a numeric suffix (e.g., _1, _2)

Folders and Organization

You can organise datasets using folders and subfolders to control visibility.

• Create folders by right-clicking a grouping

• Default name: New Folder

• Rename using F2 or double-click

Notes:

• Folders are added to the top level of a grouping or within another folder

• Folder hierarchy is limited to two levels

• Only datasets within the same grouping can be moved into a folder

Dragging and Dropping

• Drop onto a folder name to place items at the top

• Drop within an expanded folder tree at a specific position

• Dropping into a collapsed folder expands it, but preserves internal states

Folders can also be moved between parent folders within the same grouping.

3D Manager Tools

The toolbar provide the following options:

	Save Changes Save all changes made to the 3D view.
	Discard Changes Discard any unsaved changes.
	Add Plane Add a new blank plane to the 3D view.
	Section View Create a section view:  Position the reference plane to defined the section Drillhole planning tools are also available in this mode.
	Wireframing Mode Available only when a geostring is present. Enabled automatically during wireframing Yellow segments: available for selection Cyan segments: already included Click a yellow segment to add it to the wireframe surface
	Colour Tool Available for selected layer/group types: Grid layers (AGG_) Data or vector voxels (VOX_) Variable-coloured 2D symbols (CSYMB_) Variable-coloured 3D symbols Not available for image grid Raster with grid element type COLOUR, such as ECW Image, PNG Image, and GeoTIFF COLOR. layers. Click this button to activate the Colour Tool. The tool enables you to: Edit the colour display of the selected 2D or 3D group layer interactively Save custom colour configurations as scheme files (*.ITR, *.AGG, *.ZON, *.TBL, *.LUT) Apply colour schemes to layers Also available as a context menu option when the button is active. You can select multiple layers or groups of the same data type and assign a common colour scheme and distribution to all selected items. The Colour Tool will then open, allowing you to further refine the colour properties and apply the changes simultaneously to all selected layers.
	Smoothing Available when a grid layer or a data voxel layer is selected in the 3D Manager. This option is not available for image grid Raster with grid element type COLOUR, such as ECW Image, PNG Image, and GeoTIFF COLOR. layers. Also available from the context menu when the button is enabled. Click this button to toggle smoothing on or off: On: The grid or voxel display appears smoothed interactively. This affects display only; the underlying data is not modified. Off: The display honours the original grid or voxel resolution. The image appears pixelated, and colour changes occur at actual grid or voxel intervals rather than screen resolution. You can select multiple grid or voxel layers and toggle smoothing on or off for all selected items. This option can be used with any of the Display options available in the Attributes tab.

Data Types in 3D Views and their Attributes

The options available in the lower portion of the 3D Manager window depend on the currently selected 3D object type. Each object type has its own visualization and appearance attributes, allowing you to customize how data is displayed in the 3D scene.

	Planes and Surfaces
	Data Voxels
	Lithology Voxels
	Vector Voxels
	3D Drillholes
	Geosurfaces
	Geostrings
	3D Symbols
	Vector Objects
