Cylinder

The MeshCylinder command draws a polygon mesh cylinder.

#### Steps

1. Draw the base circle.

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

The DirectionConstraint options define the positive height differently.

Command-line options

##### DirectionConstraint

Direction constraints restrict the direction of the cylinder.

##### None

Pick or type a number to set the height.

##### Vertical

Creates a cylinder perpendicular to the construction plane.

• The CPlane +Z direction defines the positive direction when you type a number to set the height.
##### AroundCurve

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

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

### Solid

Caps the top and bottom openings or leave them open.

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

##### 2Point

Draws the base circle from two opposite points.

##### 3Point

Draws the base circle through three points.

##### Tangent

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

##### FitPoints

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

### AroundFaces

The number of faces around the circumference.

### VerticalFaces

The number of faces from the base to the apex.

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.

### BothSides

Creates a cylinder symmetrical across the base circle. The height of the cylinder is twice as long as you specify.

##### Cylinder

Draw a polysurface cylinder.

##### SubDCylinder

Creates a Subdivision cylinder object.
