SubDTorus

The SubDTorus command draws a subdivision torus object.

Base circle options

Radius

Pick a point or enter a radius to decide the size of the base circle.

Vertical

Draws the base circle vertical to the construction plane.

2Point

Pick two opposite points on the base circle.

3Point

Draws the base circle through three points.

Tangent

Draws the base circle tangent to one, two, or three curves.

AroundCurve

Draws the base circle perpendicular to the picked point on a curve. The center line of the torus will be tangent to the curve.

FitPoints

Draws the base circle by fitting to selected points, control points, or mesh vertices.

VerticalFaces

The number of faces along the second circle.

AroundFaces

The number of faces along the base circle.

Second circle options

Radius

Pick a point or enter a radius to decide the size of the second circle.

Diameter

Pick a point or enter a diameter to decide the size of the second circle.

FixInnerDimension

The first radius chosen sets the inner dimension of the torus and the second radius is constrained to be outside of the first radius.
