Helix
Create a solid, surface, or curve helix (coil) with a circular cross section in 3D.
Syntax
model.component(<ctag>).geom(<tag>).create(<ftag>,"Helix");
model.component(<ctag>).geom(<tag>).feature(<ftag>).set(property,<value>);
model.component(<ctag>).geom(<tag>).feature(<ftag>).getType(property);
model.component(<ctag>).geom(<tag>).feature(<ftag>).setAttribute(attribute,<value>);
model.component(<ctag>).geom(<tag>).feature(<ftag>).getAttribute(attribute);
Description
Use model.component(<ctag>).geom(<tag>).create(<ftag>,"Helix") to create a helix. The following properties are available:
Direction of the helix axis. Vector has length 3 if axistype is cartesian, and length 2 if axistype is spherical.
x | y | z | cartesian | spherical
right | left
none | custom | integer between 1 and the number of colors in the current theme
The color to use. Active when color is set to custom.
paraaxis | perpaxis | perpspine
bezier | spline
on | off
all | obj | dom | bnd | edg | pnt | off
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.
solid | surface
on | off
this | part-instance feature
xyplane | work-plane feature
Work-plane feature that defines the coordinate system. The default, xyplane, is the global Cartesian coordinate system.
For information about the selresult and contributeto properties, see Selections of Geometric Entities.

Example
The following sequence generates a surface helix and a solid helix:
Code for Use with Java
Model model = ModelUtil.create("Model1");
model.component().create("comp1");
GeomSequence g = model.component("comp1").geom().create("geom1",3);
GeomFeature h = g.create("h1","Helix");
h.set("type","surface");
h.set("rmaj",2);
h.set("rmin",0.3);
h.set("axialpitch",1);
 
GeomFeature h2 = g.create("h2","Helix");
h2.set("rmaj",10);
h2.set("rmin",2);
h2.set("axialpitch",1);
h2.set("pos","0,0,-100");
h2.set("axis","1,1,1");
h2.set("rot",60);
g.run();
Code for Use with MATLAB
model = ModelUtil.create('Model1');
model.component.create('comp1');
g = model.component('comp1').geom.create('geom1',3);
h = g.create('h1','Helix');
h.set('type','surface');
h.set('rmaj',2);
h.set('rmin',0.3);
h.set('axialpitch',1);
 
h2 = g.create('h2','Helix');
h2.set('rmaj',10);
h2.set('rmin',2);
h2.set('axialpitch',1);
h2.set('pos','0,0,-100');
h2.set('axis','1,1,1');
h2.set('rot',60);
g.run;
