Draw 3D Mine Model

This command takes the 2D series of linework and converts it to a 3D underground representation of the room and pillar mine. It uses the pillars and perimeter polylines and extrudes them to the thickness of the seam that is being mined.

The above starting linework for 3D conversion

This command will extrude the linework to either the thickness from a flat base, or to a roof and floor defined by either fixed elevations, coal sections, or elevation grid files as set by the Mine Height Method in the dialog. The input layers are defined so that the program knows what layers to look for. The Output layers are defined for the new 3D faces that are to be drawn in the assigned layers.

3dmine Once the 3D faces have been drawn, they can be viewed in the 3D Viewer Window under the View menu. In the Advanced Tab, the Shading Mode can be set to Both so that both the top and bottom of the faces will be rendered. If that is too dark, then it should be left to just Top mode.
