STEPFlatPatternExportOptions Object Preview

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

PreviewThis functionality is provided as a preview of intended future API capabilities. You are encouraged to use it and report any problems or suggestions using the Fusion API and Scripts forum.

Because this is a preview of future functionality, there is the possibility that it will change, which will possibly break any existing programs that use this functionality. Because of that, you should never deliver any programs that use any preview capabilities. For a distributed program, you should wait until it has moved from preview to released state.

Description

Defines that a STEP export of a flat pattern is to be done and specifies the various options.

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().

Properties

Name Description
filename Gets and sets the filename that the exported file will be written to. This can be empty in the case of STL export and sending the result to the mesh editor.
geometry Specifies the geometry to export. This can be an Occurrence, or the root Component. For STL, OBJ, and 3MF export, it can be a BRepBody. For DXF export, it can be a sketch of flat pattern.
isExportTempIDs Indicates if the STEP file should include the Fusion temporary IDs for faces and edges. Outside services can use these IDs with the findByTempId method of the BRepBody, which will return the given entity. The default is false.
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():
