Mapfile
Load Drillholes from a Mapfile
Use the Mapfile option to load databases or ASCII mapfiles containing drillhole locations as a layer into the current Vulcan window.
Note: The Mapfile option is only intended to work with composited mapfiles and composited databases.
Instructions
On the Geology menu, point to Drilling, and then click Mapfile to display the Geological Mapfile panel.
The resulting layer won't be saved in the currently open design database unless you transfer it to another layer using the Design > Layer Edit > Transfer option.
When you clear the layer you will not be prompted to save even if you have made edits.
