General Module Function
surfmap provides a mechanism to drape DXF files onto surfaces. You should also investigate the geologic_surfmap module.
Module Input Ports
surfmap has two input ports. The left input port should be geologic surface or other surface (such as the output of Krig_2D) and the right input port should be the output from Read_DXF.
Module Output Ports
surfmap has two output ports. The first output port (closest to the left) outputs an EVS field containing the draped line segments. surfmap will not preserve DXF entity colors in the current version of EVS. The second port outputs a renderable geometry directly to the Viewer.
Module Control Panel
The control panel for surfmap is shown in the figure above. The Z_Offset parameter provides a means to offset the draped lines from the surface so that z-buffering will not make the lines ragged or partially invisible where they intersect the surface.
If the Run Automatically toggle is not selected the module will not run unless the Accept All Current Values button is pressed. This keeps processing time to a minimum if there are multiple changes to be made upstream.
