IsoparametricCurveInput Object

Derived from: Base Object
Defined in namespace "adsk::fusion" and the header file is <Fusion/Sketch/IsoparametricCurveInput.h>

Description

The input object that defines the required input to create an isoparametric curve when using the SketchIsoparametricCurves.add method. This object is created using the SketchIsoparametricCurves.createInput method.

Methods

Name Description
classType Static function that all classes support that returns the type of the class as a string. The returned string matches the string returned by the objectType property. For example if you have a reference to an object and you want to check if it's a SketchLine you can use myObject.objectType == fusion.SketchLine.classType().
setDistributed Defines that one or more isoparametric curves will be created along the U or V parameter curves of the face. The direction is defined using the isUDirection property.
setSingle Defines that a single isoparametric curve will be created and its position is defined by its distance from the edge of the surface. The direction is defined using the isUDirection property.

Properties

Name Description
face Gets and sets the BRepFace on which to create the isoparametric curve.
isPhysicalOffset Gets how the distance of the single curve from the face edge is defined by a distance or proportionally. This property only applies when the isSingle property is True. A value of true indicates it is defined using a physical offset. To change how the offset is defined use the setSingle method.
isSingle Gets if a single or distributed curve creation has been specified. To change the type, call either the setSingle or setDistributed methods.
isUDirection Gets and sets the direction of the isoparametric curve on the surface. The curve follows the surface in either the U or V parametric direction. True indicates the U direction, which is also the default when the input is created.
isValid Indicates if this object is still valid, i.e. hasn't been deleted or some other action done to invalidate the reference.
objectType This property is supported by all objects in the API and returns a string that contains the full name (namespace::objecttype) describing the type of the object.

It's often useful to use this in combination with the classType method to see if an object is a certain type. For example: if obj.objectType == adsk.core.Point3D.classType():
quantityOrDistance Gets the quantity or distance value to be used when creating the isoparametric curve. If the isSingle property returns true, this is the distance of the curve from the edge of the face. If the isSingle property is false, this is the quantity of curves in the result. To set this, use either the setDistributed or setSingle methods.
