Draw Block Model
This command draws a block model in the CAD
drawing. Once in the CAD drawing, the blocks can be viewed with the
3D
Viewer Window or by orbiting the drawing itself. When the
command is executed, you will be prompted to select a .blk file and
a grade parameter file (.gpf file - controls coloring of the
blocks). After selecting these files, the below dialog will
appear.
Spreadsheet: In the spreadsheet you can customize the
properties of the grades including the layer name, color and
whether to draw.
Use Top/Bottom Surface Limit Grid: These toggles allow you
select constraining elevation grids. Any blocks with a centroid
above/below these elevation grids will not be drawn.
Use Inclusion Perimeter Polyline: When enabled, you will be
prompted to select an inclusion polyline. Any blocks with a
centroid outside this polyline will not be drawn.
Use Solid for Inclusion: When enabled, you will be prompted
to select a solid (.mdl file). Only blocks with centroids inside of
this solid will be drawn.
Draw as 3D Faces: When enabled, all six sides of the blocks
will be drawn as 3D faces. When this option is disabled, the blocks
will be drawn as points. Drawing the blocks as points will reduce
the demand on your computer's hardware, thus allowing for quicker
camera movements.
Auto Set Layers: This function sets the layer name by the
grade names with a specified prefix and suffix.
After clicking OK, the block model will be drawn in CAD, as
shown below.
Even though the blocks may be drawn as points, these points will be
rendered as full blocks if loaded into the 3D Viewer Window. When
the blocks are drawn as 3D faces, you may wish to modify the
SHADEMODE variable to toggle between a wireframe view and a shaded
view.
