ParametricSurface

Create a parametric surface defined by coordinate expressions in 3D.

Syntax

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

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>).importData();

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>,"ParametericSurface") to create a parametric surface. Self-intersecting surfaces are not supported. The following properties are available:

Table 3-119: Valid Property/Value Pairs
Property	Value	Default	Description
axis	double[]	{0,0,1}	Direction of the z-axis of the local coordinate system. 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.
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.
coord	String[3]	empty	Coordinates of parametric surface as function of parameters.
customcolor	RGB-triplet	Next available theme color	The color to use. Active when color is set to custom.
maxknots	int	10	Maximum number of knots in each parameter coordinate.
parname1	String	s1	First parameter name.
parname2	String	s2	Second parameter name.
parmax1	double	1	Maximum value of first parameter.
parmax2	double	1	Maximum value of second parameter.
parmin1	double	0	Minimum value of first parameter.
parmin2	double	0	Minimum value of second parameter.
pos	double[]	{0,0,0}	Position of the object.
rot	double	0	Rotational angle about axis.
rtol	double	1e-6	Relative tolerance.
selresult	on \| off	off	Create selections of all resulting objects.
selresultshow	all \| obj \| dom \| bnd \| edg \| pnt \| off	bnd	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.
workplanesrc	this \| Part Instance feature	this	Part Instance feature to take the work plane from.
workplane	xyplane \| Work plane feature	xyplane	Work Plane feature that defines the coordinate system. The default, xyplane, is the global Cartesian coordinate system.

The expressions in coord can contain functions defined in the model. If the definition of such a function is changed, the parametric surface is not automatically rebuilt. Use model.component(<ctag>).geom(<tag>).feature(<ftag>).importData() to rebuild the parametric surface after such a change.

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