Cylinder

Create a solid or hollow (surface) cylinder in 3D. The cylinder is a right circular cylinder; that is, a cylinder that has circles as bases aligned one directly above the other.

Syntax

model.geom(<tag>).create(<ftag>,"Cylinder");

model.geom(<tag>).feature(<ftag>).set(property,<value>);

model.geom(<tag>).feature(<ftag>).getType(property);

Description

Use model.geom(<tag>).create(<ftag>,"Cylinder") to create a cylinder. The following properties are available:

Table 3-42: Valid Property/Value Pairs

Property	Value	Default	Description
axis	double[]	{0,0,1}	Direction of the axis. Vector has length 3 if axistype is cartesian, and length 2 if axistype is spherical.
axistype	x | y | z | cartesian | spherical	z	Coordinate system used for axis. The value is synchronized with axis.
layer	double[]		Thicknesses of layers.
layertop	on | off	off	Apply layers on top.
layerbottom	on | off	off	Apply layers on bottom.
layerside	on | off	on	Apply layers on side.
h	double	1	Height.
pos	double[]	{0,0,0}	Center of the bottom circle.
r	double	1	Radius of bottom circle.
rot	double	0	Rotational angle about axis.
type	solid | surface	solid	Object type.
selresult	on | off	off	Create selections of all resulting objects.
selresultshow	all | obj | dom | bnd | edg | pnt | off	dom	Show selections, if selresult is on, of resulting objects in physics, materials, and so on, or in part instances. obj is not available in a component’s geometry. dom, bnd, and edg are not available in all features.
contributeto	String	none	Tag of cumulative selection to contribute to.

For information about the selresult and contributeto properties, see Selections of Geometric Entities.

Compatibility

model.geom(<tag>).create(<ftag>,"cylinder3") creates a solid cylinder.

model.geom(<tag>).create(<ftag>,"cylinder2") creates a surface cylinder.

The following properties are also available:

Table 3-43: Valid Property/Value Pairs

Property	Value	Default	Description
ax2	double[]	{0,0}	Alias for axis when axistype is spherical
ax3	double[]	{0,0,1}	Alias for axis when axistype is cartesian
x, y, z	double	0	Alias for pos

The property const is no longer available.

Example

The following commands generate a surface cylinder and a solid cylinder:

Code for use with Java

Model model = ModelUtil.create("Model1");

GeomSequence g = model.geom().create("geom1",3);

g.angularUnit("rad");

g.create("c2","Cylinder");

g.feature("c2").set("type","surface");

g.feature("c2").set("r",0.5);

g.feature("c2").set("h",4);

g.feature("c2").set("pos","1 1 0");

g.feature("c2").set("axis","pi/2 0");

g.create("c3","Cylinder");

g.feature("c3").set("r",20);

g.feature("c3").set("h",40);

g.feature("c3").set("pos","0 0 -100");

g.feature("c3").set("axis","1 1 1");

g.run();

Code for use with MATLAB

model = ModelUtil.create('Model1');

g = model.geom.create('geom1',3);

g.angularUnit('rad');

g.create('c2','Cylinder');

g.feature('c2').set('type','surface');

g.feature('c2').set('r',0.5);

g.feature('c2').set('h',4);

g.feature('c2').set('pos','1 1 0');

g.feature('c2').set('axis','pi/2 0');

g.create('c3','Cylinder');

g.feature('c3').set('r',20);

g.feature('c3').set('h',40);

g.feature('c3').set('pos','0 0 -100');

g.feature('c3').set('axis','1 1 1');

g.run;
