Polygonal Reserver - Maptek Vulcan

Maptek Vulcan has a new/old scheduling tool called the Polygonal Reserver. I call it new/old because I didn't know that it was a separate module. I originally learned about the polygonal reserver while I was working for Maptek. As an employee I had access to all the sale-able modules. It never occurred to me that this tool, which combines the functionality of two other tools, might not be part of the base module.

The polygonal reserver combines the functionality of the Polygons tool in the Model > Triangle Solid sub-menu with the Advanced Reserves Editor reporting tool. By combining these tools the polygonal reserver allows the user to interactively change the reserve area by modifying points on a polygon. The resulting triangulation and reserve results can then be used to schedule or simply report the mineable tonnage.

If you have spent any time at all with the advanced reserves editor you have probably seen the panel for the polygonal reserver, the 'name' tab under the 'polygons' section. The 'new naming convention' capability seems a little finicky and you can't exclude some of the naming conventions but the default naming convention puts a generic prefix onto the name of the polygon when naming the triangulation. I really dislike this.

The other quirky part of the tool is 'Display grade totals dynamically' on the 'Setup' tab. This functionality requires that a report specification file already be setup in the advanced reserves editor. I completely misunderstood this part of the tool when I ran it for the first time. In my defense, I don't usually use the report tool in advanced reserves so it didn't occur to me that the polygonal reserver would require it. In fact, I don't think anybody uses the report functionality in advanced reserves. Most people just export results to csv and edit the results in Microsoft Excel. Everybody else just uses the dump file. Anyway, without the report spec file there are no results to report in the dynamic window.

Once things were setup correctly, the polygonal reserver worked fine and actually saves a lot of time. I like the tool but am not sure that combining two existing tools is worth purchasing an extra module, especially since the original software package runs in the neighborhood of $50,000.
