This script allow you to hide the UI so only the viewports are visible.

First, create a new scripts directory underneath the main MoI program directory (on an equal level as \commands and \ui).

Unzip the file FullScreen.zip (for V1 use the old one – FullScreen-V1.zip) and put it in there. So the path for this file should be something like: C:\Program Files\MoI beta Dec-1-2006\scripts\FullScreen.js

Add a keyboard shortcut, for example:

Now pushing F11 will toggle the UI on or off.

This script allow checking the clock, although MoI is covering up the taskbar. You know that the little arrow button next to the Help button controls whether MoI displays as full screen or not… or not? hehe…

Unzip the file Clock.zip into the \ui folder. (The MainWindowLayout.xml file must be overwritten – actually, there is only one extra line of text added in this file (<UIPanel dock="bottom" src="moi://ui/CommandBarClock.htm" />) – so needn't worry about it.

This command draws a circle of a particular radius, placing the circle just with a single click for its center point. The circle will align itself to surfaces if the point you picked is on a surface.

To install, unzip the QuickCircle.zip to get 2 files (one .htm and one .js file) – copy these to the \commands subfolder inside of MoI's main installation folder, and then go to Options / Shortcut keys and set up a new shortcut key with QuickCircle as the command. You can then run the new command by pushing that shortcut key.

I left the default at 1.0, if you want to change the default to 0.1, you can edit the default="1.0" in the QuickCircle.htm file. But you can change the radius in the edit box.

Also after you pick a point, this command will keep running so that you can click down several points to place additional circles while inside the same command.

Nudge script lets you move selected objects, points or control points by small increments.

Unzip the file Nudge.zip (or for V2 CPlaneNudge.zip) into the \commands subfolder under your MoI main program files folder. Then go to Options / Shortcut keys, and add some new entries. For the command, put a space after Nudge, so it's 2 words like "Nudge Left". The Nudge command will look at those parameters when it runs.

It's also possible to set, for example, PageUp and PageDown for 'z' nudging, like:

and you can also add some more for doing a larger or smaller step, like:

There is Paul's variation of nudge script – NudgeViewAxis.zip – this one uses imaginary viewport XY axis instead of world axis to nudge the objects in a given direction. A syntax for command part of shortcut is the same as above except it doesn't make sense to define 'z' nudging.

See for more info.

This script allow you to create the cross-section curves through profile curves similar to Rhino's CSec.

Unzip the file CSec.zip into the \commands subfolder under your MoI main program files folder. That installs the new CSec command, but you need a way to trigger it – you can do this by adding a new keyboard shortcut under Options, for example:

Add a keyboard shortcut, for example:

To use the CSec command, you pick your CSec curves one by one in order from first to last in a circular order, and then push Alt+C, to do your CSec-ing right inside of MoI. See for more info.

This script allow you to scale the results of the array like this.

Unzip the file ScaleArray.zip into the \commands folder, then add a keyboard shortcut for ScaleArray; go to your moi.ini and add a keyboard shortcut, for example:

Add a keyboard shortcut, for example:

To use the ScaleArray command, you use any array command, but make sure to include a single point object with the objects you are arraying. The point object will become the center of the scale for each array instance.

After you do an array, select the arrayed objects (and only the arrayed objects, so for example if you do an array curve make sure the path curve is not selected), then do Alt+S (or whatever your shortcut key is) and follow a prompt.

This script allow evaluating the distance between two picked points.

Unzip the file CustomDistance.zip or Michael's CustomDistanceXYZ2.zip (it shows delta values for x, y, and z individually as well as the full distance) into the \commands folder.

Add a keyboard shortcut, for example:

Now pushing Alt+D will launch the CustomDistance command.

Original message: MoI forum.

This script allow you to keep the same distance or/and set constraint angle while drawing a polyline.

Unzip the file ConstraintPolyline.zip into the \commands folder.

Add a keyboard shortcut, for example:

Now pushing Alt+P will launch the ConstraintPolyline command. After calling this new command you can choose from three constraint mode for drawing a polyline – distance constraint, angle constraint or both of them. If you don't want to use one of them, you just type 0 (zero) or delete a value.

This script allow you to copy an objects into the set of existing target points.

Unzip the file CopyToPoints.zip into the \commands folder (e.g. C:\Program Files\MoI beta Apr-26-2007\commands)

Add a keyboard shortcut, for example:

Now pushing Alt+P will launch the CopyToPoints command. There is only one difference in comparison with regular Copy command. You must select a target points instead of picking the ones. If you check the "Delete points" option, the target points will be deleted. For selecting a target points, you can set a keyboard shortcut to select all points in the scene:

This script allow you to import point file as points, polyline or free-form curve. Points in the file should be in format like X,Y,Z (you can choose a delimiter of coordinates) with no comments or header section.

Unzip the file ImportPointFile.zip into the \commands folder (e.g. C:\Program Files\MoI beta Apr-26-2007\commands) and add a keyboard shortcut for this new command.

Some issues in using script above: The particular method that script uses to show the "get filename to open" dialog is apparently not available on Windows Vista or higher – use ImportPointFile_Update2.zip second updated version instead (you can use it along Win XP as well). It won't work with MoI v1, though.

Note: You can download updated version of the script which works on the OSX version.

Add a keyboard shortcut, for example:

This script allow for saving a coordinates of point objects to the plain text file in format X,Y,Z.

To save a point, run a command and select the point objects. Choose the delimiter character and number of significant digits of precision in the command prompt options and push done button. In the dialog box, type a name for the file including some extension like .txt, .csv, .xyz; e.g. outline.txt

To install it, unzip the file SavePointFile.zip into the \commands folder (e.g. C:\Program Files\MoI beta Apr-26-2007\commands) and add a keyboard shortcut for this new command.

Note: You can download updated version of the script which works on the OSX version.

Add a keyboard shortcut, for example:

This custom command helps you select all visible objects of a given type. The command doesn't deselect the selected objects, it means the command adds to the current selection only.

You can select the object which will define the object type to select before the command starts. In this case, when one and only one object is selected, command will run without any user intervention and in accordance with the state of a subtype checkbox the objects of the given type will become selected. The object you can pre-select:

• point
• curve (with subtype button checked either open or closed curves will be selected )
• surface (with subtype button checked either open or closed surfaces will be selected )
• edge
• face

Without pre-selected object the command prompt will stay accessible in order to enable user to check/uncheck the subtype button and pick the object. If you pick the curve or point, command will do its work and finishes. If you pick a surface, the "Done" button appears – then you will be able to finish command by pushing it (or clicking the right mouse button in the viewport) immediately to select all closed or open surfaces _or_ select edge or face in drill-in mode first to select all edges or faces.

If there is more than one object selected before command starts, it will work as described above except the pre-selected objects become deselected temporarily.

It sounds somewhat complicated, but I believe it's quite intuitive.

Unzip the file SelectByType.zip into the \commands subfolder under your MoI main program files folder. Then go to Options / Shortcut keys, and add some new entries, like:

See also MoI forum.

This custom command creates an involute spur gear profile. It is as simple as possible – just for fun. You can specify the gear by number of teeth and its module or diametral pitch (it depends on current unit settings). Then you can use that curve to make a meshing gear.

Some vague definitions:

• Module: amount of pitch diameter per tooth, in millimeters
• Diametral Pitch: number of teeth per inch of pitch diameter
• Pitch Diameter: Diameter of the circle you can see after finishing the command
• Equation: Diametral Pitch * Module = 25.4

Unzip the file SpurGearProfile.zip into the \commands subfolder under your MoI main program files folder. Then go to Options / Shortcut keys, and add some new entries, like:

! I have decided to rename this RebuildCurve custom command to avoid confusion with regular Rebuild command !

This custom command allow you to reconstruct a curve/curves using sample points evenly distributed along the original curve. You can choose from three different mode which alter the way how a new curve is built – this is possible only if there is no selected curve when triggering command, though.

Unzip the file ReconstructCurve.zip into the \commands subfolder under your MoI main program files folder. Then go to Options / Shortcut keys, and add some new entries, like:

This command closes curves by adding line segment between curve's start and end point.

To install the new command, unzip the attached CloseCurve.zip file to get 2 files: CloseCurve.js and CloseCurve.htm . Copy these files to the \commands subfolder inside of MoI's main installation folder.

Then inside of MoI either assign a shortcut key to have a command of CloseCurve, or you can also type CloseCurve to launch it by using the mini-command line entry.

See MoI's forum

This is a command for importing all the IGES files inside of a folder that you pick. (Note that it can be modified easily to do importing all the AI or 3DM files.)

To install the new command, unzip the attached ImportFolder.zip file, then copy ImportFolder.js into the \commands sub-folder inside of MoI's main installation folder.

This will give you a new command named "ImportFolder".

To trigger the command you have to set up a keyboard shortcut – go to Options / Shortcut keys, and add a new entry. Put whatever you like for the Key, for example Ctrl+I , then for the Command put in ImportFolder.

See MoI's forum

MoI allows for automatic batch processing type operations.

The first step is that you can pass the name of a script file as a command-line parameter to MoI.exe. If there are any spaces in the script file name, the entire file name should be enclosed in double quotes, like:

MoI.exe "c:\path with spaces\script.js"

The script will execute immediately before the main window is displayed, so if your script decides to exit MoI the actual MoI UI will never show up on the screen.

Michael made an example to get you started. This BatchConvert.zip script shows how to convert IGES to OBJ files.

BatchConvert.js is the file that you would overwrite with your own script, before launching MoI.exe. You just add in one line for a call to Convert() for each IGES (extension .igs or .iges) file you want to convert to an OBJ.

TheConvert() function is defined in the Convert.js library file which is included into BatchConvert.js.

Convert() handles the basic calls into MoI to open and save the files. There are some comments in there about how to control the meshing parameters, this is done by an option string you can pass to the saveAs() function. If you pass NoUI=true, the mesh dialog will not be displayed.

See for more info.

This command makes it quicker to create hollow pipes around many curves in one shot. (Note that there is the "auto place" mode for sweeping which makes it easy to create a pipe with different shape of profile even without using this custom command. Also, Michael is going to improve regular Sweep command to handle additional stuff for V2!)

However, this will only work properly on a smooth curve, you will have to wait until MoI version 2.0 before this will handle sharp corners properly.

To install this new command, download the Pipe.zip file. Copy the 2 included files (Pipe.htm, Pipe.js – updated version for V3 which should work in V2 as well) to the \commands subfolder under MoI's main installation folder in C:\Program Files.

That will install the new command, but you also need to add a new shortcut key to trigger it. To do that, go to Options / Shortcut keys, and push the "Add" button, and put whatever you wish for the key (for example P), and then for the command put in Pipe.

Now when you push that key the new Pipe command will be launched.

Select your rail curves first, then run the command. Then you will have the options for Outer and Inner radius which you can set in the command options area in the upper right corner of the MoI window.

This should speed up the creation of a larger number of pipes or tubing.

See original post.

You can also download a modified version (Pipe2.zip) which allows you to specify different outer and inner radius values which get applied to the end of the sweep. The command for this one is Pipe2, you can rename the files if you want it to replace the previous Pipe command instead.

Note this version doesn't automatically update the pipes when you enter values in, you need to push the Update button to see your changes take effect for this version. This is so you can more easily input multiple values, because Pipe does not have the same kind of interruptability that regular commands have.

See forum.

Michael was kind enough to build a tool for MoI jewelry designers to draw specific ring sizes and Jesse filled in the measurements for each country system, referencing a number of ring size charts he found online.

To install, unzip this file RingCircle.zip, placing both RingCircle files (html and jscript) in the "commands" folder of MoI – C:\Program Files\MoI 1.0\commands.

The RingCircle tool won't show up in MoI unless you turn it on with a keyboard shortcut. To make the shortcut, click the "Options" icon at the bottom right area of MoI (it looks like a yellow gear) and under "Shortcut Keys", add a key and a command. You can choose whatever key you prefer and typed in the command RingCircle.

See MoI's forum for more info.

Obj23dmWireframe converter (Michael Gibson)

This is a polygon wireframe to 3dm converter. It enables bringing polygon data (OBJ) into MoI to use as construction guides. Download the file Obj23dmWireframe.zip. Unzip it to some folder, and then you can run the Obj23dmWireframe.exe program. It will prompt you for the name of an OBJ file, and after that the name of a 3DM file. It will read all the polygon data from the OBJ file and convert the edges of polygons into line segments, and save those line segments to the 3DM file that you specified. You can then load that 3DM file into MoI and use those line segments to snap on to.

See MoI forum.

3dmCurves2DXF converter ^{V3 update} (Michael Gibson)

Download the files 3dmCurves2DXF.zip, unzip this to some folder, then run the 3dmCurves2DXF.exe program. It will ask you for the name of an input .3dm file, and then the name of an output .dxf file. It will read through the input .3dm file and convert any curve objects it finds to Spline entities in the DXF file.

See MoI forum.

And also MoI forum.

OBJ file editor ^{1th update} (Michael Gibson)

Utility program that edits the OBJ file to break larger objects up into smaller object pieces – see MoI forum and also emit material IDs – see here.

For V2 beta Jun-23-2009 or later, see this info.

Download a SeparateOBJ.zip file.

Merge OBJ (Michael Gibson)

MergeOBJ.exe utility – it will edit the .obj file to remove the grouping and object label directives so it should appear as one single mesh object – see MoI forum.

For V2 beta Jun-23-2009 or later, see this info.

Relabel OBJ (Michael Gibson)

If you run the RelabelOBJ.exe (see MoI forum) program, it will ask you for a file name, and then it will go through and replace all the object names to be based off the file's own name instead of just "object".

So for instance if you have a file named my_file.obj, if you run the RelabelOBJ.exe program on it, all the object names will be turned from just "object1", "object2", etc... into "my_file1", "my_file2", etc...

Well, you could do something like search & replace in your favorite text editor to change the names as well.

For V2 beta Jun-23-2009 or later, see this info.

Blender importer (Anthony D'Agostino)

Anthony wrote a custom blender import script that handles true normals and real-time UV coords. It also adds some pretty cool vertex colors that simulates the global-illumination from a hemisphere. The light value is calculated from the true vertex normal not the average of the face normals that surround a vertex.

Anthony highly recommend the use of his blender import script when using Blender & MoI. It reads UVs & Normals from LWO files exported from MoI3D (note: export with the vertex-welding option turned off). You can download it for free here:
http://home.comcast.net/~gamma-ray/moi/import_moi.py (or a zipped copy).

The animated GIF on this MoI forum page shows the difference between Anthony's importer and the standard one that ignores MoI's true normals.

3dm2sculpt converter

You can get a 3dm2sculpt converter from here – that will enable converting from a .3dm file that MoI saves into a .tga sculpt map texture file. See the page in the "How to use ?" section for some instructions: http://wiki.secondlife.com/wiki/3dm2sculpt

iges2step converter Note that V2 is able to handle STEP I/O directly!

MoI can import/export IGES files … to translate STEP file to IGES or vice versa you can use iges2step converter/viewer; see http://iges2step.narod.ru/. After finishing an installation process you must reboot your computer before first launching this converter!
