Editor

The layer view allows for the voxel model to be edited from above. Simply select a lithology and draw the model in, as you would in a paint program. Changing the layer allows for the drawing in of lithologies at deeper depths. Please note that on the first few layers there may be sections which are air (due to the DTM), and are thus not editable.

The profile view allows for the voxel model to be edited from the side. Simply select a lithology and draw the model in, as you would in a paint program. Changing the profile allows for the drawing in of lithologies at different locations.

The display of magnetic data or gravity data is changed upon calculation of either data type.

Options

Calculations

Calculations can be done by choosing one of two options from the menu bar at the top of the program:

Tips

The ranged copy function can be very useful in getting a starting model going. Draw in your basic lithology boundary and copy it over a range of applicable depths. You can now quickly correct this either in the Layer Editor or the Profile Editor
