RE: [geonet]: 3-D contour map

[Natalie Green]

Hi Colin,   This is not currently an option in the 3D Tool.   To put an opaque (or translucent) box around the bottom of your grid then would require five grids or images oriented so they connect at the corners and the four sides would need an edge that matches the relief at the edges of the top grid.   These grids could be added in version 5.1.6 with the new "Grid / Display grid / Single grid to a 3D view..." (GRIDIMG3D GX).  With this GX, additional oriented grids can be added to an existing view.  In cases where no orientation information is contained in the grid (the usual case for most grids), you can define the orientation, selecting either a plan orientation (horizontal) at a given elevation for the bottom of the box, or a section orientation (vertical) with a specified origin and azimuth for the sides.   This is probably more work than it is worth though, so I have added this idea to our Feature Request list.   Cheers, Natalie   _______________ Geosoft Inc.
