The Bend Tool: This can be used to bend a shape; the straight purple line shows the shape completely straight, whereas the line on the right shows the curvature that is taking place on the object. This tool is very useful for making arches but does require a lot of sub-divisions to make a smooth and fluent curve, therefore bringing up the poly count.The Flare Tool: This caused the bottom half of your object to be scaled in or out, this can be used for the knot at the bottom of a balloon (as shown), this example is the flare tool put to its max setting.The Sine Tool: This tool can be used to make your object wave in and out, This is done by changing the amplitude and wavelength. The straight purple line shows the shape as normal whereas the wavy line shows the result if you extrude or scale the shape. Keep in mind this also requires a lot of sub-divisions to make a smooth and fluent curve.The Squash Tool: this is used to scale down your object only from the top and bottom. The straight green line shows the area that will be subjected to your input; the green circle shows where it will affect your model, if you model goes outside this, it will not be affected.The Twist Tool: this tool is used to rotate your object around itself causing a screw effect. Dependent on your input the object may be more or less warped by the tool.The Wave Tool: this tool is used to create water ripple like surfaces, the purple lines show how the tool will affect your object.
Booleans
Union: This tool is used to connect two shapes together; this allows you to move them as one without selecting both. Although this also creates a Ngon on the cubes faces. This is easily fixed by using the multi-cut tool.Difference: This tool is used to cut away at a shape with the faces of another shape; in the example, a sphere has been used to cut into a cube. Although this also creates a Ngon on the cubes faces, this is easily fixed by using the multi-cut tool.Intersection: This tool cuts away any other shape and only leaves behind the part where the two shapes met, this example is a sphere touching a cube. What is left behind is where the two shapes overlap. Again, this creates a Ngon that can be fixed with the multi-cut tool.
