A new v4 beta (version Aug-28-2018) is now available for download here: http://moi3d.com/beta.htm , also linked to from the download page on the main web site.

The main focus for this beta is performance enhancements.

3DM files will now use multiple CPU cores for loading so large files should load significantly faster and show a progress bar.

Also the display engine has been enhanced to take advantage of modern GPUs - display data is now cached in the GPU's VRAM which should result in faster redraw speed for large files.


Other bug fixes and changes:

Mac version multiple windows - Add "Window" menu to Mac version top menu. Shows all open files and allows switching between them easier. Also support Cmd+Tilde (Cmd+~) and Cmd+Shift+Tilde for switching to next/prev window.

Mac AMD performance - fix problem with default buffer location with OpenGL on some AMD cards that was causing slow redraws on some machines like iMac pro.

Updated Mac file open behavior. To match the Mac document based application framework behavior, if a file is opened by drag/drop or by double-clicking on the desktop icon do not open a new window for it if there is an existing window with it already open.

Object snap labels on left side - Add moi.ini option to make object snap labels shown to the left of the target point, can be useful if you're drawing directly on a screen such as with a Cintiq screen. Can be set in moi.ini under:
[Drawing Aids]
ShowObjectSnapLabelToLeft=n

Shortcut keys update - On Windows if there is a [Shortcut Keys Mac] section of the moi.ini file, read and write shortcuts from there so you can copy the moi.ini file over from Mac to Windows. Fixes issue reported on the forum by Matt here:

File notes - Add notes property that is saved to and loaded from .3dm files. Can be accessed by setting up a shortcut key with:
script: moi.ui.createDialog( 'moi://ui/NotesDialog.htm', 'resizeable' );

Viewport right click option - Add option for v3 behavior of right clicking in a viewport working as a shortcut for pushing the Cancel button when a command only has Cancel and not Done. Can be set in moi.ini under:
[View]
DoRightClickCancel=y

Add new appdata directory option - MoI will now look for an appdata directory that has been created alongside "commands", "ui", etc... and if found will use that location as the appdata folder, to make it possible to store everything within a single directory.

Add moi.ini setting for selection hit test radius
[View]
SelectionHitTestRadius=12

Scene browser scripting - Added script access to scene browser items so it is possible to make a startup script that expands sections on program startup. To do that put the following in a .js file in your Moi appdata startup folder:
var items = moi.ui.sceneBrowser.rootItems;
for ( var i = 0; i < items.length; ++i )
items[i].expanded = true;
