Cone

Create a right circular cone or cone frustum (conical frustum, truncated cone) in 3D.

Syntax

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

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

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

Description

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

Table 3-39: Valid Property/Value Pairs

Property	Value	Default	Description
ang	double	arctan(1/2) (about 26.565 degrees)	The cone’s semi-angle; that is, the angle between the axis and a generator of the conical surface.
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.
h	double	1	Height.
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.
pos	double[]	{0,0,0}	Center of the bottom circle.
r	double	1	Radius of bottom circle.
rot	double	0	Rotational angle about axis.
rtop	double	0.5	Radius of top circle.
specifytop	angle | radius	angle	If axistype is angle, the radius of the top circle is given by the ang property. If axistype is radius, the radius of the top circle is given by the rtop property.
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>,"cone3") creates a solid cone.

model.geom(<tag>).create(<ftag>,"cone2") creates a surface cone.

The following properties are also available:

Table 3-40: 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

Create a cone with an apex:

Code for use with Java

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

double h = 3;

double r = 2;

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

g.angularUnit("rad");

g.create("c1","Cone");

g.feature("c1").set("r",r);

g.feature("c1").set("h",h);

g.feature("c1").set("ang", Math.atan(r/h));

double ang = g.feature("c1").getDouble("ang");

Code for use with MATLAB

model = ModelUtil.create('Model1');

h = 3;

r = 2;

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

g.angularUnit('rad');

g.create('c1','Cone');

g.feature('c1').set('r',r);

g.feature('c1').set('h',h);

g.feature('c1').set('ang', atan2(r,h));

ang = g.feature('c1').getDouble('ang');

Create a truncated and rotated cone:

Code for use with Java

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

g.feature("c2").set("pos", "1 -2 4");

g.feature("c2").set("axis", "1 -1 0.3");

g.feature("c2").set("rot",Math.PI/3);

g.run();

Code for use with MATLAB

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

g.feature('c2').set('pos', '1 -2 4');

g.feature('c2').set('axis', '1 -1 0.3');

g.feature('c2').set('rot', pi/3);

g.run;
