Scale

The Scale tool allows you to make any selection larger or smaller by changing the scale percentage factor. By using the various handles, you can quickly scale in a single axis dimension. After applying a transform amount, you may press the middle mouse button to re-apply the previous offset amount, making it easy to apply an edit multiple times. The command can be activated in the Basic sub-tab of the Modeling viewports, in the menu bar under Edit > Transform > Scale, or by pressing the R keyboard shortcut.

Move Tool

In the component modes, Vertices, Edges, and Polygons, the tool affects the selected geometry directly. When nothing is selected, it affects all active foreground geometry. Active foreground items are those that are visible and selected (highlighted) in the Items (Scenes) List. In Items mode, the tool affects all the currently-selected items in the Item List. If nothing is selected, then the tools appear to do nothing. In Material mode, it works the same way as in any of the component modes. Lastly, in the Center and Pivot modes, it modifies the Center or Pivots respectively.

Note: You need to select either the Center or the Pivot itself (depending on the mode), prior to activating the tool, as in the Items mode. With no selection, the tool appears to do nothing.

When you define any of the various falloffs Modo provides, application of the tool can be attenuated across a user-defined area. For more on using falloffs, please refer to Using Falloffs.

Once the tool becomes active, Modo draws the relevant tool handles within the viewport: arrows for moving, boxes for scaling, and circles for rotating. At this point, you can simply click and haul anywhere inside the desired viewport to interactively transform the geometry. Additionally, you may prefer to utilize the various tool handles, constraining the application of the function to one or all three axes.

The various tool handles are color-coded to match the coloring of the different axes: red for X, green for Y, and blue for Z. Hover the mouse over a specific handle until it changes to a yellow color, and then click and drag to modify. To interactively scale the size of the handles themselves, you can use the - (subtraction) and = (equals) keys on the keyboard to adjust them: subtraction makes them smaller, while equals makes them larger. Additionally, for the Scale tool, there is a small circle at the intersection of all three handles that you can use to uniformly scale the selection interactively. To move your object in the 3rd dimension (forward and backward) in the 3D Viewport press Shift + Ctrl/Cmd + right-mouse-button and drag.

The Transform tool also respects the settings for the Action Center, and originates the appropriate action from the defined position. For more information on understanding and using Actions Centers, please refer to Specifying Action Centers and Falloffs .

Transform Scale Options

The following Transform options are available for adjusting the Scale tool:

Scale Tool Panel

Scale

Use the X, Y, and Z input fields to apply specific scaling values. When adjusting an object interactively in the viewport, the Scale input fields display the current scale factor applied, providing useful user feedback.

Absolute Handle

Applies an additional function to the tool handles, allowing you to scale the handle itself without affecting the transform amount. In some cases, this provides finer control over very large or very small adjustments.

Negative Scale

Enables/disables Modo's ability to interactively apply negative scale values when manipulating the tool handles in the viewport. When disabled, you can always input negative values in any of the input fields directly.

Pivot

Only available in Items mode. Allows you to easily modify an item's pivot position without the need to go into Pivots mode.

Note: The Gimbal option must be disabled in order to adjust the Pivot option.

Gimbal

When enabled, you can assign rotation values numerically, but may arrive at a situation that produces "gimbal lock" - the loss of one rotation axis when another axis' value is too close. You can avoid this by disabling this setting, but you are then unable to apply specific values within the input fields.

Slip UVs

Only in component selection modes. UV values are generally fixed to specific vertices; subsequently, further edits to the geometry may warp, deform, or otherwise distort the UV values in undesirable ways, requiring you to adjust the map or redo it altogether. To avoid this undesirable result, you can enable the Slip UVs function, so as to not disturb any existing UV mapping applied to the geometry.


Slip UVs function disabled: texture warping occurs.	Slip UVs function enabled: texture remains even.

Morph

Only available in component modes. Determines how Modo treats stored Morph information, when applying transforms to geometry (Move, Rotate, Scale). In previous versions of Modo, in order to transform a morph, along with its base, it needed to be selected in the Vertex Map list. If it wasn't, relative morph map data, when recalled, would produce distorted, undesirable results. If you are unaware of the requirements, it's easy to accidentally mess up a model. To remedy this problem, there are now three options controlling how the morph map vertex data is dealt with when applying any transforms:

• None - Unselected Morph data is not affected, though selected (visible) morphs can still be transformed, independent of their source.

• Transform - With this option selected, Morph data is transformed, along with the base mesh.

• Keep Positions - With this option selected, Morph data is converted into an absolute morph map and all vertices retain their pre-transformed positions.

Normal

Only in component modes. When working with vertex normal maps, the Normal options control how the map values are affected. Refer to Transform Vertex Normals for more information.

• None - Vertex normal map values won't be affected at all by Transform operations.

• Edit - Only vertex normal map values are modified by the tool, and only in the selected Vertex Map.

• Update - All vertex normal map values, selected or otherwise, and any selected geometry, is modified by the Transform operation.

Child Compensate

Only available in Items mode. When disabled, passes along the transform value to any child items of the current selection. When enabled, the child items ignore any transform values. This is useful to transform a single item in a hierarchy, such as adjusting a joint, allowing it to be re-positioned relative to other elements without moving child items.
