Surfer Beta Version History

Official version history and changelog information for the current version of Surfer Beta.

Surfer Beta 32.0.240 (June 5, 2026)

Everything included in the 31.3.316 update

New Features and Improvements

• 3D View: Contour Slice | Path | Base layer shows all base layer objects even if turned off in 2D map
• 3D View: Drillholes: Keyword: Symbology: Save/Load symbology
• 3D View: Isosurface: Colormap Editor: Add histogram data
• Comments pane: default window configuration should not have Comments pane open
• Convert Layer: Assign layer coordinate system to map coordinate system, when converting from layer that does not support coordinate systems (e.g. surface layers)
• Coordinate Systems: NFT (Paris) / Lambert II transform updated to improve accuracy
• Coordinate systems: prompt for coordinate system when unreferenced layers are added to referenced map, or referenced layers are added to an unreferenced map
• Coordinate Systems: updated available definitions to EPSG current version
• User interface: rename 'Grid Data' to 'Create Grid', 'Map Wizard' to 'Create Map', and add both to a Wizards group on the Home page of the ribbon

Fixes

• Users could get a "Waiting for printer connection" error when cut/copy & pasting in an open plot window, when default printer was unavailable
• 3D View: Zero-length isosurface mesh vertex normals when using the 'Rank' filter
• Coordinate Systems: custom Units won't stick
• Crash after cancelling update when changing Advanced contour levels colormap
• Grid Data: Recurring error "Value must be > 0" for Alpha value when alpha shape is not being used
• Internal Error when going back to Cross Validation (MinimumCurvatureGridder.cpp)
• Scale Bar: dragging to decrease height past 0" makes it larger in the negative direction
• Undo/redo do not retain CS info when adding new Empty Base layers to a map

Surfer Beta 32.0.198 (April 22, 2026)

Fixes

• Base(raster): 24bpp images that are reprojected lose their color
• DXF Export: contour labels at very edge of map are missing, instead of exported as polygons

Surfer Beta 32.0.194 (April 15, 2026)

Everything included in the 31.2.277 update

New Features and Improvements

• Add Comments: add to the bottom of the right click context menu
• Base layer import (vector): attributes in scientific notation that are >=1 (e.g. 0.1000000000000000E+01) are imported as Text instead of Numeric

Fixes

• 3D View: changing 3D Grid Filter can cause the contour slice level error "Too many levels, maximum is 5000"

Surfer Beta 32.0.163 (March 4, 2026)

New Features and Improvements

• 3D View: 
  • 3D Grid: Filter module (filter type, edge handling, nodata handling) for volume renders, block renders, isosurfaces, and contour and image slices
  • 3D Grid: apply up to 4 clipping planes
  • Drillhole: Open Drillhole Manager from the Drillhole layer Properties and context menu in Contents
  • Image slices: save slice as grid, save slice as image, and set the orientation to a polyline or polygon in a base layer or all polylines and polygons in a base layer
  • Contour slices: save slice as grid, save slice as image, and set the orientation to a polyline or polygon in a base layer or all polylines and polygons in a base layer
• Comments: add, display and edit comments for collaboration and instruction
• Legend: 
  • Base layer: add Legend entries for base layers that don't use symbology (Symbology is set to None)
  • Layers: option to display the samples for layers in multiple columns
• Update the user interface style

Fixes

• Internal Error when XYZC gridding anisotropy has invalid ellipsoid (CmdGridData.cpp)
