Individual Surface General Properties

Surfer can automatically Create Surface for each contact you have defined from your drillhole data. These surfaces, which are visible in the 3D view, are defined by the contact points and can be further customized. Before creating surfaces, you must first create contacts for your drillholes using Create Contact.

When you select an individual surface in the Contents window, the Properties window will display a General and Conflicts tabs for that contact's surface.

In the General page, you can set the color and opacity for the surface, in addition to set thing the minimum distance between that surface and the one below it. You can also click Save the grid if you just wish to save the grid file for that individual surface. You can also click 3D View | Drillhole Surfaces | Save Grid on the ribbon.

You can edit the individual surfaces created from contacts. To access these options, select the individual surface within the Drillhole | <Drillhole Layer Name> | Surfaces section of the Contents window. In the Properties window select the General tab to view the surface editing options.

  • Color: The surface's color can be customized. By default, surfaces created from a keyword method inherit the color of the lower interval, while others default to the contact symbol color. The topography surface defaults to brown, and the base surface defaults to 50% black.

  • Opacity: This property allows you to set the surface's transparency, with a default of 100% (fully opaque). The topography surface has a default of 90%.

  • Minimum distance below: This value defines the minimum thickness of a unit, ensuring a minimum distance between this surface and the surface below it.

  • Save grid: Click and the standard Save Grid As dialog appears so you can save the grid file for that surface.
