    Arrowheads: Changed size on zoom when in blocks. This is fixed.
    Black meshes: Transforming a render mesh caused it to turn black. This is fixed.
    BlendSrf: Picking a set of edges that forms a closed loop automatically proceeded to picking the second set of edges. This meant you had to pay careful attention to the command prompt so that you don't accidentally cancel the command by pressing Enter. This is fixed. In addition the the "Undo" option is now visible even when the edges form a closed loop.
    Block: Exporting block instances did not carry layers of nested blocks with them. This is fixed.

    DocumentProperties: The scriptable version of this command did not report the current angular settings correctly. This is fixed.
    DocumentProperties: If the document units were changed and geometry was scaled accordingly, Undo would not undo the scaling. This is fixed.
    DupEdge and SplitEdge: Arrow indicators for closed surface seams no longer display.
    EdgeSrf: Did not show arrows when surface edges were selected as input. This is fixed.
    EdgeSrf: In V2 EdgeSrf picking order determined the singularity location. In V3, there was no such control. This is fixed.

    Render: Using custom resolutions, the display displaced in the render window. This is fixed.
    Revolve: Revolving with a profile segment on axis made a bad surface. This is fixed.
    Revolve: Ignored angle setting order. This is fixed.
    RotateCamera: The scriptable version of RotateCamera was not properly updating the viewport target. This is fixed.
    Save Points: Scripting option Precision renamed to SignificantDigits.
    Scale2D: Did not properly pay attention to picking in alternate viewports. This is fixed.
    Select: Edge arrows always display when edges are selected. They should only display when there is an ambiguity about what is being selected. This is fixed.
    Select Objects: When postpicking in commands (Join, Offset, etc.) that allow selecting just one object, unsuitable objects will not be selected with SelAll, SelSrf, etc.
    Selection: New feedback has been added to selection commands to indicate when nothing is selected.

    Toolbar: Problems with toolbars have been fixed: Cancel symbol did not work properly in some cases and flyouts did not happen instantly when toolbar definition was empty.
    Treefrog: New "favor memory over speed" option makes it use less memory for rendering. This may allow you to render larger scenes than you were able to render before.
    Trim: Canceling a trimming operation did not work properly in some cases. This is fixed.

    When entering relative coordinates in inch format, "r" works but "@" did not. This is fixed.
    When exporting to IGES, the Maximum Degree setting did not restrict the surface degree. This is fixed.
    When HP1050C is the current printer, the paper size and the preview do not work properly. This is fixed.
    When in analysis modes, turning on control points incorrectly also displayed surface isocurves. This is fixed.
    When rendering a maximized viewport with the render resolution set to viewport resolution, the rendered image was larger than the viewport size. This is fixed.
    When using .x, .y, or .z functions while drawing a curve, the drawn object disappeared, making it impossible to snap to its control points. This is fixed.
    When using maximized viewports, the Tab drawing constraint incorrectly caused the viewport to cycle to the next viewport. This is fixed.
    When using the scroll wheel to browse through bitmaps in the EMap list, Rhino switches between the last two used bitmaps in the top of the list. This is fixed so it scrolls through the entire list.
    Window selecting an entire object for ExtractSrf, incorrectly extracted all the surfaces, but left the original object intact as well. This is fixed.

    With ShowCamera, objects directly behind the camera apex point, displayed upside-down in the perspective viewport while being dragged. This is fixed.

    Bug Fixes:
    Several crash bugs fixed in MergeSrf, SetPt, and Scale have been fixed. These fixes may also fix other unreported crashes in Beta 15.
    Selection of objects inGhostedViewport is now better - you can select objects through ghosted surfaces by picking on wires.
    Fixed crash bugs in cancelling mechanism. This fix affects any command that printed "Press Esc. to Cancel" on the command prompt. Prior to this fix, the cancelling mechanism could corrupt memory, causing unrelated crashes in the future. This is now fixed.
    Fixed several obscure crash bugs. Commands such as Sweep1, Sweep2, BlendSrf, MatchSrf, and others may have crashed because of this bug.
    Toolbar buttons updated to reflect changed command name CurvatureGraph.
    Alt + letter key combination did not work to access several menus. This is fixed.
    The "Add object", "Remove Object", and horizontal divider do not resize correctly in the CurvatureAnalysis dialog box.
    When Dimensions Precision is set to 1, dimensions below 1 do not round to the nearest unit. This is fixed.
    Scaling dimensions left the arrowheads behind. This is fixed.
    Lights did not scale when changing units settings. This is fixed.
    Fillet now displays error information on the command line when it fails.
    The Intersect command could give a different output depending on the order the surfaces are picked. This is fixed.
    An error message that displayed when no default template was found, has been fixed.
    A bug that caused files to Open slowly across Samba links has been fixed.
    Several OpenGL display and crash bugs with specific files and graphics cards have been fixed.
    When printing to 1:1 scale, the printed page always used model units as inches no matter what the setting in the Print dialog. This is fixed

    Undo did not properly refresh the location of spotlight control points. This is fixed.
    Placing the Camera and Target locations from the ViewportProperties dialog box sometimes locked up Rhino. This is now fixed.
    The Weld command did not retain vertex normal information. This is fixed.
