Significant improvements to the Map view: 1. Add scale bar. 2. Map image produced by drag and drop, contains scale bar and north direction. 3. Symbols have a reasonable size at all scales. A damping factor is added to avoid symbols growing too much with zoom. 4. Annotations are properly placed: In front of the dip tick for planes, and in front of the arrow for lines.

- Rotate data and Variable rotation menus now work with more than one dataset. - Rose diagram menu only activates with lines or planes datasets have entries

. Fixed a bug introduced in the previous version 6.6, where the selection of two datasets was not recognized. This affected the line on plane, arcs between lines, and fault kinematics menus. . Fixed a bug in the line on plane operation, where the trend and plunge of the corrected line were not written.

. Document window allows toggling the Data view (command+D) and Annotations view (command+T). . In the Inspector -> Stereonet view, add a color well to set the fill color of the primitive circle . In the Inspector -> Contours view, add a check box to smooth the contours as in Vollmer (1995) . Lines with filled or gray symbols are now plotted with a white outline. These make them more clear. . Fix the coloring of the contours to use the whole range of the color scale bar. . In the 3Dview Ctrl + click now works and disable drawing of lines and planes inside the bowl. . Small circle button (+SC) in the Data view now has a correct tip tool saying "Add Small Circles dataset" . Numerous optimizations. . Numerous fixes for deprecated methods.

Fix a bug: Contours are no longer drawn outside the stereonet view.

. Remove data and info drawers and instead have them in the same window. Drawers are a neat solution but they were deprecated long ago. . Small Circles are now datasets and can be added using the +SC button. . Overturned planes can be indicated by the letter combination OV under the dip quadrant column. Poles to overturned planes point upwards (they have negative plunge). . The key modifier for drag and drop of the Stereonet and Map View is now the command key. The previous Shift key conflicted with the functionality of the Map View. . Strike of planes or Trend of lines in quadrant format (e.g. S30E) is now read properly when parsing a text file. . Fixed lots of deprecated code. . Update the Help document accordingly. Stereonet3D still uses the Help Indexer but there can be issues updating to the latest Help document. Please let me know if you find some. . Minimum deployment is macOS 10.13 . Compiled in Xcode 15.2

Google Earth structural geology symbols are now in http://www.ux.uis.no/~nestor/Public/Symbols/ Minor changes to the documentation Minor bug fixes and removal of deprecated methods Compiled in Xcode 12.3

A better solution for labels in OpenGL 3D view Improve initial location of windows and panels

- Change server for symbols of exported Google Earth files to Richard Allmendinger's server - Remove full screen menu - Fix labels in 3D view for new Retina displays - Fix drag and drop of Map view - Fix measuring distances in Map view - Map view don't ask for user location - Compiled in Xcode 11.4

Built in Xcode 10.2 Minor bug fixes

. Fix colouring of Beach Ball diagrams . Apple Notarized . Compiled in Xcode 10.1

. Make the angle between lines, angle between planes, and intersection between two planes methods more robust. This also corrects other related bugs. . Correct several bugs in the Fault Plane solution (Beach Ball diagram) implementation

Further fixes to the fault plane solution routine: . Fix bug when nodal planes are vertical and horizontal . Don't allow negative plunge in P axis Decrease the size of strike and dip ticks if extent of Map view is small

Improve the functionality of the Fault slip analysis submenus . Compute fault slip analysis only if striae are on fault plane within 2 degrees error . Beach ball diagram from fault plane solution . Beach ball diagram from two ad hoc T and P axes: This is great to quickly create a beach ball diagram . Add a menu to remove arcs and beach ball diagrams from fault slip analysis

This is a major update: . Allow for multiple cylindrical best fits, conical fits, and mean vectors. This is useful for comparing fits to different datasets. . If in default view, change the background grid when entering lines or planes as poles (picking great circle) on the plot. This provides an intuitive understanding of the stereonet. . Emailed data from iPhone Apps StereonetMobile and FaultKinMobile by Richard Allmendinger can be imported to Stereonet3D as a text file. . Add a Slip Sense column to lines datasets to specify sense of slip of striae on fault plane. . Under the Plot menu, new fault slip analysis group of menus including: a. HW slip direction, b. Movement planes, c. Tangent lineation, d. T and P axes, e. Unweighted Moment tensor sum, and fault plane solution.

. Add copy and paste of dataset entries

. Add options to read geographic coordinates of planes or lines entries in UTM . Update copyright to 2017

. Allow outgoing connections in entitlements for better performance of Map View . Fix minor bugs and interface glitches

- minor optimisations - updated documentation

- restore dropping text files into the stereonet to load them

Fixed a bug when setting view direction Fixed a bug when reporting directions cosines of planes in format 2 Fixed a bug when deallocating datasets Improved performance of 3D view

Automatic Reference Counting Improved performance of Map View

Fixed minor interface glitches

Built in Xcode 6.0.1

. Planes in format 2 are now given as Dip, Dip Direction. Careful: When importing text files of planes in format 2 this new convention should be followed. . Copy datasets between open documents by drag and drop from/to datasets table. . Copy entries between open documents or from other applications (e.g. Excel) by drag and drop to entries table.
