Deforming Items

With Modo's various deform tools, you can produce soft, organic deformations (such as with the Soft Move and Sculpt tools) or hard, mechanical forms (such as with the Shear and Bend tools). Many of Modo's deforming tools are hybrid tools that combine functions of action centers, falloffs, and transforms into a single tool. These tools offer a wide array of options to contort and otherwise shape the geometry into any form you wish. With the Toolpipe function, you can make your own tools from a combination of functions. For information on using a specific tool, click a link below to see that tool's topic.

Deform
	Element Move	Allows you to quickly edit individual component elements of a mesh.
	Element Push	Allows you to push individual component elements of a mesh along their normals.
	Flex	Provides a natural, organic bending-type deformation.
	Soft Move	A tool preset that consists of the Transform tool with Radial Falloff. With this tool preset, you can select vertices, edges, or polygons and move them.
	Soft Drag	A tool preset that consists of the Move tool combined with the Screen Falloff. It allows you to select vertices, edges, or polygons, and then drag them to affect their neighbors.
	Shear	Combines the Transform tool with a Linear falloff.
	Smooth	Reduces the jaggedness or roughness of a surface.
	Jitter	Repositions selected items or components based on a seed number and a range value for the X, Y, and Z axes.
	Quantize	Evaluates the contour of the selected geometry and shuffles the vertices to align to a three-dimensional grid.
	Symmetry Tool	Allows you to interactively correct minor symmetry errors.
	Soft Selection Move	Moves the selected geometry rigidly, while gradually attenuating the translation outside the selected area, defined by the Soft Selection Radius.
	Soft Selection Rotate	Rotates the selected geometry rigidly, while gradually attenuating the rotation amount outside of the selected area as defined by the Soft Selection Radius.
	Soft Selection Scale	Scales or re-sizes the selected geometry rigidly while gradually attenuating the scale amount outside the selected area defined by the Soft Selection Radius.
	Soft Selection Transform	Allows you to simultaneously move, rotate, and scale the selected geometry rigidly while gradually attenuating the translation outside selected area defined by the Soft Selection Radius.
	Linear Align	Aligns selected vertex or UV positions along a line.
	Radial Align	Moves selected vertex or UV positions along a circle or polygon.
	Quick Align	Aligns geometry to another piece of geometry interactively in the 3D viewport.
	Ground Align	Aligns the selected geometry down to the ground.
	UV Transform	Transforms a source mesh's vertices to the world position of the surface of a target mesh, using a UV map on the target mesh.
	Path Generator	Uses an existing curve to provide a path for other tools to walk and evaluate.
Rotate Deform
	Twist	Combines the Axis Rotate tool with a Linear Falloff.
	Bend	Deforms selected geometry in a curved manner. For example, bending a straight cylinder into an arc.
	Vortex	Combines the Axis Rotate tool with the Cylindrical Falloff.
	Swirl	Combines the Axis Rotate tool with a Radial Falloff.
Scale Deform
	Push	Moves the selected geometry along the selected item's normals.
	Sculpt	Allows you to shape polygons with a brush-like paradigm to smoothly deform a surface.
	Taper	Combines the Transform tool with a Linear Falloff.
	Bulge	Combines the Transform Scale tool with a Radial Falloff to produce a swelling effect on the target object or surface.
	Flare	Combines the Push tool with a Linear Falloff.
