Interpolation Curve

Create a curve interpolating or approximating a sequence of points in 2D or 3D.

model.component(<ctag>).geom(<tag>).create(<ftag>,"InterpolationCurve");

model.component(<ctag>).geom(<tag>).feature(<ftag>).importToTable();

model.component(<ctag>).geom(<tag>).feature(<ftag>).importData();

To create an interpolation curve use model.component(<ctag>).geom(<tag>).create(<ftag>,"InterpolationCurve") The following properties are available:

Table 3-67: Valid Property/Value Pairs
Property	Value	Default	Description
filename	String		If source is file, the file that contains the data.
rtol	double	0	Maximum relative error. 0 implies interpolation.
source	table \| file \| vectors	table	Whether data is specified as vectors, a table, or read from a file.
struct	sectionwise \| spreadsheet	spreadsheet	The data format if source is file.
table	double[][]		Data points, size N*sdim.
type	open \| closed \| solid	open	Type of curve.
x	double[]	{}	x-coordinates for data points.
y	double[]	{}	y-coordinates for data points.
z	double[]	{}	z-coordinates for data points.
selresult	on \| off	off	Create selections of all resulting objects.
selresultshow	all \| obj \| dom \| bnd \| edg \| pnt \| off	dom in 2D; edg in 3D.	Show selections, if selresult is on, in physics, materials, and so on; in part instances; or in 3D from a plane geometry. 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.
workplanesrc	this \| Part Instance feature	this	Part Instance feature to take the work plane from (in 3D only).
workplane	xyplane \| Work plane feature	xyplane	Work Plane feature that defines the coordinate system (in 3D only). The default, xyplane, is the global Cartesian coordinate system.

Use model.component(<ctag>).geom(<tag>).feature(<ftag>).importToTable() to read data from the file defined by the filename property and store the data in the table property. The source property is also changed to table.

If source is file, the interpolation curve is not automatically rebuilt when the data in the file changes. Use model.component(<ctag>).geom(<tag>).feature(<ftag>).importData() to rebuild the interpolation curve after such a change.

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

Example

The following commands create a curve interpolating four points in 2D:

Code for Use with Java

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

model.component().create("comp1");

GeomSequence g = model.component("comp1").geom().create("geom1", 2);

g.create("ic1","InterpolationCurve");

g.feature("ic1").set("table",new double[][]{{0,0}, {1,0}, {1,1}, {0,1}});

g.run();

Code for Use with MATLAB

model = ModelUtil.create('Model');

model.component.create('comp1');

g = model.component('comp1').geom.create('geom1', 2);

g.create('ic1','InterpolationCurve');

g.feature('ic1').set('table',[[0,0]; [1,0]; [1,1]; [0,1]]);

g.run;
