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

Surfer Beta 27.0.147 (Sept 7, 2023)

New Features and Improvements:

• 2D/3D Grids: Assign NoData relative to a 2D grid surface
• 3D Grids: Assign NoData using 2D polygon
• 3D View: Block Render
• 3D View: Drillholes: depth scaling issues when Survey depth in different units than Collars/Points/Intervals depth
• 3D View: Drillholes: vertical exaggeration should not change the shape of the path/interval cylinders
• 3D View: import and orient an image file (e.g. TIF/JPG)
• 3D View: Lighting: set lighting relative to view
• 3D View: new specular lighting controls
• Base Map (vector): give option to not change properties when reloading base map file
• File | Save All to save all open files at once
• Grid Data: XYZC: Assign NoData using 2D polygons, 2D convex hull or 2D alpha shape
• Grid Data: XYZC: use data directly from Drillhole Manager
• Grid from Contours: increase speed of detecting intersections
• Grid from Contours: avoid 'Contour source cannot contain intersecting polylines with different Z values.' error
• Label/numeric format: rounding: 5 should be rounded up

Fixes

• Crash when undo
• CSV Import: imported more values after a special character that should have stopped the import
• Internal Error after undoing breaking apart a surface layer (SceneList.cpp)
