- How to expand existing surfaces in SHOTPlus™ version 6.
Methods
There are three methods of expanding a surface in SHOTPlus™, they are:
- Expand by distance.
- Expand to blast extents.
- Expand to polygon.
Expand by distance will expand a selected surface by a user-defined distance. The selected surface can be expanded multiple times. To Expand by distance:
- Select the surface to expand.
- From the main toolbar select Tools > Surfaces > Expand surface.
- In the Expand surface dialog box select the Expand by radio button and enter the desired expansion distance in metres.
- Select Expand. The Expand button can be selected multiple times to continually expand the selected surface by the desired expansion distance.
- To finish select either:
-
- Cancel – to cancel the expansion and close the Expand surface dialog box.
- OK – to accept the expansion and close the Expand surface dialog box.
-
When expanding a surface by distance, the method of expansion and the points used to extrapolate the expansion can be adjusted.
To adjust the settings for Expand by distance:
- Select Advanced from the Expand surface dialog box to open the Expand surface advanced options dialog box.
Surfaces can be expanded by a distance using two different methods:
- Plane of best fit - Extrapolates the surface based on the points used to generate the surface.
- Flat - Extrapolates the surface horizontally.
To adjust the method used for expansion:
- Select the preferred option from the Method drop down box in the Expand surface advanced options dialog box.
SHOTPlus™ uses the points used to create the original surface to complete the expansion extrapolation. This extrapolation can use all points that were used to create the surface, or only points within a user selected radius.
To use all points:
- Ensure the Use only nearby points checkbox is unselected.
To use only selected points:
- Ensure the Use only nearby points checkbox is selected.
- Define the search radius for the points to use for extrapolation.
Expand by blast extents will expand the selected surface to beyond the collar and/or toe points of the outermost holes within a blast pattern. To Expand to blast extents:
- Select the surface to expand.
- From the main toolbar select Tools > Surfaces > Expand surface.
- In the Expand surface dialog box select the Expand to blast extents radio button.
- Select Expand.
- To finish select either:
-
- Cancel – to cancel the expansion and close the Expand surface dialog box.
- OK – to accept the expansion and close the Expand surface dialog box.
-
Expand surface to polygon will expand a selected surface to the extent of a selected polygon. To Expand surface to polygon:
- Select the surface to expand.
- Select the polygon to expand the surface to.
- From the main toolbar select Tools > Surfaces > Expand surface to polygon.
