CustomSheetSize Object Preview

Derived from: Base Object
Defined in namespace "adsk::drawing" and the header file is <Drawing/Drawing/CustomSheetSize.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

Custom width and height cannot exceed 5000 mm × 5000 mm (millimeter units) or 200 inch × 200 inch (inch units). Horizontal and vertical zone counts cannot exceed 1000.

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
height Gets and sets the height of the sheet.
horizontalZones Gets and sets horizontal zones. Minimum 2 for drawing creation.
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():
verticalZones Gets and sets vertical zones. Minimum 2 for drawing creation.
width Gets and sets the width of the sheet.
