Surfer Version History

New Features and Improvements

• 3D View: Drillhole: Contact Surfaces: Save Grids: prompt to save external spatial reference file when appropriate
• Assign Coordinate System: warn the user that Custom coordinate systems won't persist
• Assign Coordinate System: when a search only has one result, expand the coordinate system tree to that result
• Contents: a coordinate system icon is displayed next to a map or layer name that is unreferenced, when the map or other layers are referenced
• Grid Data: option is available to set the Coordinate System for the output grid
• Icons: the Change Filename icon in dialogs has been updated

Fixes

• 3D PDF Export: exporting 3D surface maps from 3D view has unexpected colors/effects in PDF
• 3D View: Contacts: could not create contact points when Hole ID has preceding space
• 3D View: Drillhole Surfaces are not created correctly when a geotransform is present for the map
• 3D View: Vector Data: Save Data doesn't do anything when exporting to DXF
• DXF export: 'Use Only Spatial Information' no longer exports anything
• DXF/DWG export: Error: "Duplicate Record name: <object> Encountered" when exporting to DXF or DWG and two layers have same name
• DXF import: some areas that should be white or transparent are black/opaque
• DXF import: some HATCH entities were imported with a distorted shape 
• Export Contours: Error "Unable to open '<file path>.cpg'. Access is denied" when exporting a 2D or 3D SHP to a virtual network drive
• GCS: Conversion between EPSG 32631 and 2154 is incorrect
• Internal Error when exporting isosurface mesh to 3D PDF (TrPolymesh.cpp)
• Internal Error when overlaying maps (MapFrameNode.cpp)
• Measure: using the same measure tool instance for a different map uses the units of the original map

New Features and Improvements

• 3D View: 
  • 3D Grids: Image slice: change interpolation mode for pixels (like color relief layer)
  • 3D PDF Export: use names from Contents in the Model Tree (instead of object type)
  • Drillholes: create depositional and erosional surfaces from drillhole contact picks
  • Fly-Through: save recording in MP4 format
  • Isosurface: add "Ignore" option for handling NoData interface
  • Import Image Orientation: set Orientation to a polyline or polygon in a vector file
  • Performance: reduce property view refreshing during camera movement
  • Record window
  • Vector Data: add Point Labels
  • Vector Data: rename "Features" property page based on layer type
• Assign Coordinate System: add EPSG code in parameters pane for each CS
• Base import: DWG/DXF: add option to import each layer from file as separate Base layers
• Coordinate systems: 
  • Map: Assign Now could be active if you set units for an unreferenced coordinate system
  • Show the EPSG code in Properties
  • All UTM/Mercator projections should be linear and accurate
  • Changing Target coordinate system: instead of warning with OK, prompt to Assign Now
  • Favorited coordinate systems that are corrected and never modified should inherit the correction
  • Issue warning when users try to change the Source coordinate system
  • When overlaying referenced layers in unreferenced maps, use one of the coordinate systems for the combined map

  • Over 13,000 coordinate systems are now supported (searchable via EPSG code)

• Gridding method: 3D Nearest Neighbor for XYZC gridding
• Import/Export DWG
• Import DXF: elevation data stored as block attributes are not accessible in Surfer
• Import/Export DXF: update DXF import and export to use the new/updated DWG functionality
• Large Grids: Color Relief: General Properties: improve response time when changing Hill Shading Parameters
• Legend: 
  • Add \layername to template options (post, drillhole, and base layer)
  • Add contour layers as single-line or multi-line entry
  • Add Drillhole layers without symbology, and improve legends when drillhole layer does have symbology
  • Drillhole layer: row height should only be impacted by the properties that are shown
  • Middle align symbols and text in sample entries
  • Pie chart symbology: include "Fill sample size" with line props around the fill
  • Post layer: use \layername in default template when size is Fixed and color columns set to None or Explicit
• Map Scale Bar: made sure the map scale bar object was named consistently within the program
• Ribbon: new Help page

Fixes

• 3D View: 3D PDF/VRML Export: axis titles are not exported
• 3D View: Walk: WASD keys no longer move camera in Walk mode
• Base layer: Legend links for invalid legends using old serialization should not be saved
• Coordinate Systems: 
  • Geotransformation of Lambert Nord France is not correct
  • EPSG: 3388 has incorrect coordinate system definition and does not account for 180 lat bound
  • Cannot change Map coordinate system from WGS84 UTM zone 14N to 15N
  • Portuguese National Grid and ETRS89/Portugal TM06 are not converting the coordinate system properly
  • Projection error converting from WGS84 UTM zone 23N to any other coordinate system
• Crash after copying/pasting map, adding legend and saving
• Crash in automation when importing a grid
• Crash when cleaning up after graphics driver SEH exception
• Download Online Maps: entering lat/lon extents is really difficult or impossible (TAB, clicking in another box or Paste doesn't work)
• DXF Import: lines are straight when they should be curved
• Groups: Symbols drawn in existing Groups are upside down
• Internal Error when creating 3D view after using Set Limits (NormalizingTransform.cpp)
• Internal Error when exporting 3D View to 3D PDF (TrPolymesh.cpp)
• Internal Error when measuring (MeasureToolWnd.cpp)
• Invisible layer using shared grid at the top prevents display in 3D View
• Legend: Copy/Paste when contains a drillhole layer and a base layer causes Surfer to become unresponsive
• Surfer Warning about unreferenced layers is either empty or too large to display on the screen when there are too many layers
