Dimension Object Preview

Derived from: EcadObject Object
Defined in namespace "adsk::electron" and the header file is <Electron/Dimensions/Dimension.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

Dimension annotation on a PCB board or schematic sheet that displays measured distances, angles, or radius.

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
dtype Measurement style of this dimension.
extlength Length of the extension lines, in internal units.
extoffset Offset of the extension lines from the measured points, in internal units.
extwidth Width of the extension lines, in internal units.
id Identifier of the object.
isValid Indicates if this object is still valid, i.e. hasn't been deleted or some other action done to invalidate the reference.
layer Layer number (1-based index into the layer stack).
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():
precision Number of decimal places in the displayed value.
ratio Character width to height ratio.
size Text height (character size), in internal units.
unit Unit type for the displayed dimension value.
visible True if the dimension value is visible; false if hidden.
width Line width of the dimension stroke, in internal units.
x1 X coordinate of the first measurement point, in internal units.
x2 X coordinate of the second measurement point, in internal units.
x3 X coordinate of the third point, in internal units.
y1 Y coordinate of the first measurement point, in internal units.
y2 Y coordinate of the second measurement point, in internal units.
y3 Y coordinate of the third point, in internal units.
