Tip

The following are some examples of how to use the Solid Lab tab functionality.

Please go through each exercise to practice running different operations on the demo dataset.

Many of these operations can be included in one Operation set to achieve a final outcome.

Creating final phase solid for Pit1 Stage 2

Example, the following operations can be performed in one Operation Set to achieve a final phase solid for Pit1 Stage 2.

Clipping a Surface

Use Clip Surface by Polygons operation to reduce the size of a surface file. Loading smaller files into memory excluding data not required.

  1. Import surface file (can be imported from a file or from the Layers panel).

  2. Drag & drop files from the Layers to the Operations panel, click on the icon and drag.

  3. Using the polygon tool draw a polygon around the area required.

  4. Run the operation by pressing the blue triangle sign.

  5. Click on Result row to see the outcome in the viewport.

  6. Click on the green arrow icon to save the result to the Layers panel.

Creating a Solid for a Pit Stage

This operation is used for a pit containing 2 phases, to create a solid phase of Stage 2 excluding Stage 1.

To run this operation the following surface files are required:

  • upper surface topography (preferably clipped),

  • design surface file for Pit1_Stage1,

  • design surface file for Pit1_Stage2.

  1. Create a solid above the Pit1_Stage2 design.

  2. Create a solid below the Pit1_Stage1 design and the natural surface file.

Intersecting Solids

  1. Intersect the 2 solids.

    1. When intersecting solids click on the row with the added solids. In the viewport, you will see two solids

    1. , one above the other, as shown below. This is not a very clear example, as we cannot really see intersecting area.

      1. For better clarity, change the transparency of these solids.

      2. Rotate the resultant solids for better seeing the overlapping area. This area is the result of the intersection.

Subtracting Solids

  1. In the same Solid Operation Set “pit1_s2”.

    1. Remove operation Create Solid From Polygons.

    2. In the Create Solid Below All Surfaces operation field change the Surfaces selection to include "Clipped Topo".

    3. In the Intersect Solids operation field change the Solids selection to include "Output From Operation #1" and "Output From Operation #2".

    4. Run the operations by pressing blue play button.

    5. Save the result to the Layers panel.

  2. Click Add Operation and select "Subtract Solids".

    1. In the Inclusive Solid field include "Output From Operation 3".

    2. In the Exclusive Solid field add previously exported "Pit1_stg_1_solid".

  3. Run the operations by pressing the blue play button.

  4. Select the Result row to see the result in the viewport.

  5. Save the result to the Layers panel as “Pit1_stg2_solid”.

Cleaning Solid from Remnant Blocks

As a result of overlapping solids and surfaces, you can see a lot of remnant blocks around the resultant solid that you want to remove to facilitate further scheduling. Two basic methods to accomplish this goal are outlined below.

Method 1. Reducing Complexity

Tip

To clean remnant solids use Reduce Complexity option from Add Operation dropdown. This operation allows small remnant solids to be removed from a larger solid

layer

.

  1. Add operation Reduce Complexity and from Solid dropdown select

required

  1. solid to import, or drag and drop it from the Layers panel.

  2. Specify

the minimum volume

  1. :

    1. Minimum Volume accepted,

    2. Maximum Error - triangulation error limit

and pinch tolerance

    1. ,

    2. Pinch Tolerance to remove smaller volume areas. All solids with a volume below this value will be removed

Building set of Operations

  • Create an Operation set.

  • Add operation Clip Surface By Polygons (Exclude Outside).

  • In Surfaces dropdown import topo required from layers or files.

  • Draw one closed polygon and press play button to run results.

  • Add operation Create Solid Below All Surfaces.

  • Import surfaces “pit1_s1” and “Output From Operation #1”.

  • Add operation Create Solid Above All Surfaces.

  • Import surfaces “pit1_s2”.

  • Intersect the results of Steps 2 and 3 (#2, #3).

    • Reduce the Complexity for the result of step 4 (#4) as shown below.

      1. .

    2. Run the operations by pressing the blue play button.

    3. Select the Result row to see the result in the viewport.

    Method 2. Creating Solid From Polygon

    Tip

    To clean remnant solids use Create Solid From Polygons option from Add Operation dropdown. This operation includes drawing polygon around area to keep excluding remnant solids to be removed from a larger solid.

    1. Add new operation - Create Solid From Polygons.

    2. In the Layers panel, toggle pit1_s2 solid, resulting from intersection and subtraction operations.

    3. Draw a closed polygon around the solid area to keep using the Create Polygon tool from the top toolbar.

      1. Make sure that the drawn polygon is closed, otherwise, you’ll get an error message.

      2. Excluded from the polygon area will be removed from the final solid.

    4. Using the up and down arrows, place the Create Solid From Polygons operation in front of Intersect Solids operation.

    5. Add the outputs of operations #1, #2 and #3 to the Intersect Solids operation.

    6. Run the operations by pressing the blue play button.

    7. Select the Result row to see the result in the viewport.

    If all steps are done correctly, you should get a result like on the right - a solid with smoother boundaries, without extra remnant artefacts, fitting the outlined polygon.

    Display the original solid to see the difference.
