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.
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.
