The SubDTruncatedCone command creates a subdivision truncated cone object.

Steps

1. Draw the base circle.

2. Pick a location or type a number to set the height.

   The positive direction of the height is different based on the selected DirectionConstraint option.

3. Draw the end circle.

Base circle options

DirectionConstraint

Direction constraints restrict the direction of the truncated cone.

1. None: Pick or type a number to set the height.

Use elevator mode, object snaps, or other modeling aids to help picking a location.

The cursor location is the positive direction when you type a number to set the height.

2. Vertical: Creates a truncated cone perpendicular to the construction plane.

The CPlane +Z direction is the positive direction when you type a number to set the height.

3. AroundCurve

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

The curve direction is the positive direction when you type a number to set the height.

Solid

Caps the top and bottom openings or leave them open.

Radius

Draws the base circle by picking the center point and a radius point.

Diameter - Circumference - Area - ProjectOsnap

2Point

Draws the base circle from two opposite points.

3Point

Draws the base circle through three points.

Radius

Tangent

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

Point - FromFirstPoint - Radius

FitPoints

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

VerticalFaces

The number of faces in the vertical direction.

AroundFaces

The number of faces around the circumference.

CapFaceStyle (Tri/Quad)

Select to use triangle or quad faces to fill the top and bottom openings.

This option is only visible when AroundFaces is an even number (4, 6, 8...), and Solid=Yes.

Tri is always used when AroundFaces is an odd number.

End circle options

Radius

Pick a location or enter a number to set the end circle radius.

Diameter

Pick a location or enter a number to set the end circle diameter.
