property
Adds properties to objects.
Notice that UV cluster properties and vertex color properties can
only be added to clusters which are always complete, see Geometry.AddCluster
method.
Note: This command uses output
arguments. C# and some scripting languages (such as JScript,
PerlScript and Python) don't support arguments passed by reference
so you need to use the best workaround for your situation:
For scripting languages this command returns an ISIVTCollection which you can
use to get the output arguments.
For C# you can use the XSIApplication.ExecuteCommand
method to call this command. ExecuteCommand packs the output
arguments into a C# System.Object containing an Array of the output arguments (see
Calling
Commands from C#).
| AddProp( PresetObj, [InputObjs], [Propagation], [PropertyName], [Value] ); | 
| Parameter | Type | Description | 
|---|---|---|
| PresetObj | String or a preset object (see SIGetPreset) | One of the Property Presets | 
| InputObjs | String | List of objects. Default Value: Currently selected objects | 
| Propagation | siPropagationType | Propagation type for property Default Value: siDefaultPropagation (node) | 
| PropertyName | String | Name of property | 
| Value | XSICollection | Returns the new properties in an XSICollection. Note: For backwards compatibility, ClassName returns "Object" when you test this collection, but if you test it with XSICollection.Type, it returns "XSICollection". Tip: Each member of the returned collection is a Property object. |

' This example demonstrates how to add the RenderMap property to both a sphere and

' them as members of the returned collection.

' Note: In this example we are using the XSIApplication.ClassName method instead
'       of the VBScript TypeName function to provide a distinction between
'       class type and what we test with the Type property, but you can use
'       either.

/*
        This JScript example illustrates how to use the AddProp command to add an 
        annotation property to a null object. Of special interest in this example
        is how we use the returned object to extract an array of output arguments
        (since JScript does not support output arguments).
        Note: In this example we are using the XSIApplication.ClassName method 
        which is the equivalent of the VBScript TypeName function (for which
        there is no native JScript equivalent).
