Block model display

You can use this function to display the exterior faces of the block model. Displaying the exterior faces of the block model can help you visualise and understand the model that you have created. Features that influence the manner in which the block model is drawn are the block model constraints and the colouring attributes.

To run this function: Choose Block model > Block model > Display, or...

In the Function Chooser, type BM GRAPHICS DRAW, and press ENTER.

If you do not apply block model constraints, you will see the entire model. If the colouring attributes are not defined, the entire model is displayed in the same colour.

To achieve effective results, you must use constraints and colouring attributes.

Fields on the Draw block model form

Field	Description
Style	Blocks: Displays the block model as 3D blocks. Point Cloud: Displays the block model as points based on the centroid of all the blocks that exist in the model. This can be useful for viewing blocks in centre of the model. Regularised Cloud: Displays the block model as points based on the centroid of all the blocks in the model. This is helpful for visualising reblocking.
Include internal blocks?	Selected: The internal blocks are loaded into Graphics as well as the external faces of the model. Note: This can make displaying the block model very slow. Cleared: Only the outside faces of the model are displayed. Note: This field is available only if you selected Blocks.
Block Size	The block size to use, which controls the level of detail in the block model. The smaller the block size, the greater the detail. Note: This field is available only if you selected Regularised Cloud.
Clear constraints?	Selected: Any existing constraints are cleared before the data is displayed. Cleared: The data constrained by the any existing constraints before it is displayed.
Remove slicing?	Selected: Any previously defined slicing of the block model is removed before the data is displayed. Cleared: The data is loaded and the previously defined sections are redisplayed with the new data.
Rescale?	Selected: Graphics is rescaled to display all of the data in the block model, in Plan view. Cleared: Graphics is not rescaled.
Point Cloud Marker	The style of marker used if you are displaying the model as a point cloud.
Marker Size	The size of the Point Cloud Markers. A size of 1.0 displays a marker approximately 3% of the screen size.

Output

The exterior faces of all blocks which meet the constraints are displayed to represent the block model. Block faces are coloured using the attribute colours defined by BM GRAPHICS ATTRIBUTE COLOUR.

Note: If you are using viewing planes, and the block model is entirely outside the view corridor, the block model might not be visible. If the block model is partly inside and partly outside the view corridor, the blocks on the plane of intersection with the view corridor are displayed.
