Property	Value	Default	Description
color	none \| custom \| integer between 1 and the number of colors in the current theme	none	The color of the selection, either given as an integer indicating a color in the color theme, or as a custom color in the customcolor property. Coloring is only available when selresult in active.

customcolor	RGB-triplet	Next available theme color	The color to use. Active when color is set to custom.
endcond	none \| zerocurv \| tangent	none	Condition at endpoint: none, a tangent condition, or zero curvature
endtang	double[sdim]	{1,0} or {1,0,0}	Tangent direction at endpoint (if endcond is tangent).
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.

Table 3-71: Valid Property/Value Pairs for InterpolationCurve

none | custom | integer between 1 and the number of colors in the current theme

none

The color of the selection, either given as an integer indicating a color in the color theme, or as a custom color in the customcolor property. Coloring is only available when selresult in active.

contributeto

String

none

Tag of cumulative selection to contribute to.

customcolor

RGB-triplet

Next available theme color

The color to use. Active when color is set to custom.

endcond

none | zerocurv | tangent

none

Condition at endpoint: none, a tangent condition, or zero curvature

endtang

double[sdim]

{1,0} or {1,0,0}

Tangent direction at endpoint (if endcond is tangent).

filename

String

If source is file, the file that contains the data.

rtol

double

Maximum relative error. 0 implies interpolation.

source

table | file | vectors

table

Whether data is specified as vectors, a table, or read from a file.

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.

startcond

Type of curve.

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.

double[]

{}

x-coordinates for data points.

double[]

{}

y-coordinates for data points.

double[]

{}

z-coordinates for data points.

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.

When building the feature, if the start condition or end condition is zero curvature, the corresponding (currently inactive) tangent direction property should be set to the tangent vector of the resulting curve.

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.
