Adding a Stope Section

For a Polygonal Pillar shape, the Stope Section is not limited to a rectangle and can be any arbitrary (non-overlapping and closed) polygonal shape.

The first step in creating an CPillar model with Polygonal Pillar shape (after setting any necessary Project Settings) is to create the Stope Section boundary.

To define the Stope Section boundary:

1. First, make sure you have selected the Stope Section view (select the Stope Section option from the drop-down menu on the toolbar). By default, a valid rectangular 10 by 10 section is defined.
2. Select Add Stope Section from the toolbar, the Boundaries menu, or the right-click menu.
3. Enter the vertices of the boundary as described in Entering Coordinates.
4. If you need to define an arc segment, or a complete circle, this can easily be done. See the Drawing Arc Segments topic for details.
5. If you make a mistake while entering coordinates, you can undo vertices during coordinate entry, with the undo command (type u in the prompt line or select Undo from the right-click menu).
6. Coordinates can also be entered into a convenient table, in which you may type coordinates directly, or import coordinates from an existing file or spreadsheet.
7. The Stope Section boundary must always be closed. To close the boundary, after all vertices are entered, right-click and select Close Boundary, or you can type c and ENTER in the prompt line. This automatically and correctly closes the Stope Section boundary, and saves the user the trouble of having to re-enter the first vertex to complete the boundary.
