It is possible to set up a keyboard shortcut to do an incremental save, where a number in the filename will be bumped on each save, like file01.3dm, file02.3dm, file03.3dm, etc...

To do this, go to Options / Shortcut keys, and add a new entry with a key of whatever you like (for example, Alt+S), and IncrementalSave for the command.

Reconstructs a curve by sampling points and generating a new curve through those points.

The Rebuild command does not currently have a button in the UI, it must be set up on a keyboard shortcut (under Options / Shortcut keys) or have its command name typed in (press Tab first to enter a command name) to launch it.

Rebuild can be used to simplify a curve that is overly complex or messy or has too many points in it to be easily manipulated by control point editing. It can also be used for the reverse as well, to add a lot more points to a simple curve if you want to have a higher level of detail available for editing.

There are 2 modes, a "Refit to tolerance" mode where you enter a distance tolerance value and as many points are added as needed (not necessarily uniformly) to maintain the new curve within that distance of the original curve, or a "# of points" mode where you tell it a specific number of evenly spaced points to sample for creating the new curve.

Flips the positive normal direction of an open surface to the other side.

This doesn't affect much in MoI itself but can be used to reverse the normals for polygons generated from open surfaces when saving to a polygon mesh file format.

The Flip command does not currently have a button in the UI, it must be set up on a keyboard shortcut (under Options / Shortcut keys) or have its command name typed in (press Tab first to enter a command name) to launch it.

Merges split up edge fragments into longer combined edges.

The edges must be tangent where they touch each other in order to be merged together into a single edge.

The Merge command does not currently have a button in the UI, it must be set up on a keyboard shortcut (under Options / Shortcut keys) or have its command name typed in (press Tab first to enter a command name) to launch it.

Replicates a gemstone along a set of curves on a surface, aligning the gem to the surface normal.

The ArrayGem command does not currently have a button in the UI, it must be set up on a keyboard shortcut (under Options / Shortcut keys) or have its command name typed in (press Tab first to enter a command name) to launch it.

ArrayGem uses a different spacing method than the other array commands - along with the objects to be arrayed you also include a base circle and the spacing that you provide becomes the separating distance between each placed circle along the target area.

For the targets you pick a surface, and a set of curves that have been projected on to that surface.

Note that for this command to work properly, there must be a base circle previously drawn and also included among the objects that you want to have copied. The base circle should be selected at the same time along with the objects to copy.

The center of the base circle will become the point that is placed on to the surface, and the diameter of the base circle will be taken as the size of the object.

An example:

Moves objects away from a common center point giving an effect similar to an exploded diagram.

If a single solid is selected, its faces will be separated and moved apart, otherwise if multiple objects are selected the objects will stay whole and move apart from one another.

The ExplodeMove command does not currently have a button in the UI, it must be set up on a keyboard shortcut (under Options / Shortcut keys) or have its command name typed in (press Tab first to enter a command name) to launch it.

Creates a box or rectangle that frames the current selection.

The BoundingBox command does not currently have a button in the UI, it must be set up on a keyboard shortcut (under Options / Shortcut keys) or have its command name typed in (press Tab first to enter a command name) to launch it.

Creates a point object marking the center point of the bounding box around the current selection.

The BoundingBoxCenter command does not currently have a button in the UI, it must be set up on a keyboard shortcut (under Options / Shortcut keys) or have its command name typed in (press Tab first to enter a command name) to launch it.

Shrinks the underlying surfaces of the selected objects to remove areas of the surface that were extending larger than the trimming boundaries.

The ShrinkTrimmedSrf command does not currently have a button in the UI, it must be set up on a keyboard shortcut (under Options / Shortcut keys) or have its command name typed in (press Tab first to enter a command name) to launch it.
