Torus

These three values establish the 3D location for the center of the primitive.

Determines the overall outside width of the torus.

A Cross Section width and Height setting, determining the sizing of the ring cross section of the torus.

These three values establish the dimensions of the torus. The tool is set to 50cm, 50cm, 50cm by default.

The sides are the latitudinal edges of the torus running from top to bottom. By default, the primitive uses 24 sides. By increasing this value, you can increase the number of "cuts" in the shape. This is useful if you plan to deform the mesh, as these segments act as hinges during deformation operations. This also increases the smoothness of the capsule by adding extra facets. If you plan to apply subdivision surfaces to this shape, you can use a lower number of sides.

The segments are the longitudinal edges of the torus running from right to left. By default, the primitive uses 12 segments. By increasing this value, you can increase the number of "cuts" in the shape. This is useful if you plan to deform the shape, as these segments act as hinges during deformation operations. It also increases the smoothness of the shape by adding extra facets. If you plan to apply subdivision surfaces to this shape, you can use a lower number of segments.

This value sets the radius of the hole in the middle of the torus.

You can use this option to determine the type of polygons created:

• Face - creates standard, unsmoothed polygon faces.

• Subdivs - creates Subdivision Surface smoothed polygons.

• Catmull-Clark - creates Pixar Catmull-Clark smoothed polygons.

Raising this value above zero (0) attenuates the shape towards a more cubic or box-like form.

This X, Y, Z choice allows you to quickly change the orientation of the primitive.

When this button is active, a UV map is automatically generated for the geometry created with the tool. This is a very useful option if you plan to UV map the model you are creating from the primitive, as it provides a baseline UV map that you can massage later in the modeling process. In many cases, this can reduce the amount of work required to map the model.

Adjusts the aspect ratio and related area size of UV polygons to reduce the distortion in the primitives UVs.

Use this option when you create a Torus that does not have equal radius values. By default, the UVs that are generated for the primitive are distorted and displayed in red and blue in the UV viewport of the UV layout. To view distortion, in the UV viewport, click Options... and then enable Show Distortion.

Enabling the Distortion Compensation option reducing the distortion automatically and produced cleaner UVs. This feature also works in real-time as you edit the attributes of the primitive before committing to the final values.

Provides three types of behavior for corner and side tool handles:

• Resize from Center - Resizes both sides of the primitive at the center, when dragging a corner or side handle.

• Resize - Resizes the shape at the opposite side, when dragging a corner or side handle.

• Move All - Moves the primitive instead of resizing.

Tip:  You can also move the shape by clicking and holding the Ctrl key when in another handle mode.

When enabled, displays the bounding box corner handles.

Determines the size from the center of the Torus to the outer bounding box edge - the radius - of the torus.
