A new v3 beta (version Nov-6-2012) is now available for download here: http://moi3d.com/beta.htm , also linked to from the download page on the main web site.

New stuff:


Mac version should now work fine with the latest OSX system updates 10.8.2 and 10.7.5 without needing any other settings adjusted.


New DXF file format support for import and export - focused on curve entities like lines, polylines, arcs, circles, splines. Should help with data transfer to and from various 2D CAD programs. When exporting you can choose to export either a 2D projected view which will flatten the curves by a view projection, or to export the 3D curve data. It's saved as an AutoCAD 2000 version DXF file.


Updated closed surface skinning to do periodic closed surfaces - fixes problems with closed fillets, blends, and sweeps where the generated surface was not smooth at its closing seam area. One recent one reported here: http://moi3d.com/forum/index.php?webtag=MOI&msg=5376.1 which should now be smooth in the seam area where there was a crease happening previously.


Fixed a regression in the last geometry library update that was causing failures with analytic intersections between planes and cylinders and preventing some Booleans from working. Also fixed another regression that was messing up Inset as reported here: http://moi3d.com/forum/index.php?webtag=MOI&msg=5508.1


New "Bounding box center" button for Transform > Move, Copy, Scale, and Scale1D commands. On the first prompt where you can pick the base point for these transform commands there is now a "Bounding box center" button you can push to use the center of the object's bounding box as the base point, to make it easier to move the object's center point to a specific location.


Update properties panel size readout - units calculator. Make the units label in the size: line of the properties panel to be clickable separately, when clicked it brings up a mini units calculator that allows displaying the size in different unit systems.
Requested on the forum here: http://moi3d.com/forum/index.php?webtag=MOI&msg=5503.1
Demo here: http://moi3d.com/forum/index.php?webtag=MOI&msg=5503.14
It's also now possible to have a script change which units will be used inside of the top-level size: line inside the properties panel, here's a keyboard shortcut that switches the display in that one area from the current unit system to inches or back again:
script: /* Set property panel units display */ var sp = moi.ui.sidePane; sp.g_PropPanelUnits = (sp.g_PropPanelUnits == 'Inches' ? '' : 'Inches'); sp.UpdatePropertiesPanel();


Relabeled the vertex normals options for LWO format to make one setting labeled as "Modo 601 / LightWave v10" style normals, since as of Modo 601 it uses the same style as LightWave v10 for importing LWO vertex normals.


Updated Extrude to point - when extruding a line segment to a point, make a trimmed plane for the triangular face generated rather than a surface with a singularity (collapsed edge) at the tip.


Updated tapered extrude - added a "flip" checkbox, requested on the forum here: http://moi3d.com/forum/index.php?webtag=MOI&msg=5403.1


Updated tessellator to fix triangulation issues in certain circumstances to fix the meshing bug reported on the forum here:
http://moi3d.com/forum/index.php?webtag=MOI&msg=5365.4 also fixed a crash bug in the tessellator reported here:
http://moi3d.com/forum/index.php?webtag=MOI&msg=5515.1


Updated curve antialiasing - new option for using thinner style antialiasing in the display engine. Can be set in moi.ini under:
  [View]
  UseThinAntiAliasing=y
Or toggled by a keyboard shortcut with: script: /* Toggle thin anti-aliasing */ moi.view.useThinAntiAliasing = !moi.view.useThinAntiAliasing;
Was requested on the forum here: http://moi3d.com/forum/index.php?webtag=MOI&msg=5370.1


New project to cplane drawing aid - Implement new drawing aid mode which can be used to project all snap points onto the construction plane, by using the following scripts on a shortcut key:
  script: /* Toggle projecting snaps to CPlane in ortho views */ moi.drawingAids.projectToCPlaneOrtho = !moi.drawingAids.projectToCPlaneOrtho;
  script: /* Toggle projecting snaps to CPlane in ortho and 3D views */ moi.drawingAids.projectToCPlaneAll = !moi.drawingAids.projectToCPlaneAll;
Requested in forum here: http://moi3d.com/forum/index.php?webtag=MOI&msg=5371.1


Updated Network surfacing command - fixed bug where the new fitting options from the previous beta did not get applied to 3 or 4-sided networks since those were handled by a special case Coons patch method instead. Now 3 or 4 sided networks will generate a regular Network surface with the same option in effect, and there is a new "Exact" option which shows up for 3 or 4 sided networks which will make a Coons patch with no refitting of the input curves.


Fixed a bug where the main window did not store its size properly if the window was closed while it was minimized, when closing it by right-clicking on the Windows task bar.


Fixed a bug importing spheres and surfaces of revolution from Rhino when certain additional rotation properties were set on them, fixes a bug reported on the forum here:
http://moi3d.com/forum/index.php?webtag=MOI&msg=5389.1


Updated ArrayGem - allow point objects to also be selected as target objects for creating copies instead of only path curves.


Some scripting fixes - fix problem in function signature for moi.vectorMath.createFrame() that caused different behavior when arguments were left out between Windows and Mac, disabled script timeout that would abruptly cancel scripts that ran a tight loop for too long, fixed problem where pasting a script fragment into the xyz coordinate box would evaluate it twice, and make factory.getCreatedObjects() work with async factories by waiting for the async factory to finish its work before returning back to the script with the generated objects.


Updated installer - put full version name on the "MoI" program shortcut so that multiple versions will be more distinctly labeled when they show up in the MRU area of the Start menu. Fixes the problem reported here: http://moi3d.com/forum/index.php?webtag=MOI&msg=5405.9


Various other minor fixes.


EDIT: Originally this was a Nov-5 version, but that had a bug where all of STEP, SAT, and IGES import/export was crashing, I've updated it to a new Nov-6 release with that bug fixed now.
