You emails help me alot. Message 6 of Most of the code from the example is not required if you make the change I noted.
The default value for the attribute is set with the TextString property. If the Constant property is set to True, prompting for a new value is disabled when the block with the attribute definition is inserted. The tag string identifies each occurrence of the attribute and is assigned with the Tag property. You can use any characters except spaces or exclamation points.
AutoCAD changes lowercase letters to uppercase. Once the attribute definition is defined in a block, whenever the block is inserted using the INSERT command, you can specify a different value for each attribute reference that is not defined as being constant. When a BlockReference object is created, the object does not contain any attributes that are defined in the BlockTableRecord object until they are appended to the BlockReference object using the AppendAttribute method.
Before appending the attribute to the BlockReference object, use the SetAttributeFromBlock method to copy the properties of an AttributeDefinition object to an AttributeReference object. The HasAttributeDefinitions property can be used on a block table record to see if it contains attribute definitions.
Attribute definitions created on model space or paper space are not considered attached to any given block. This example creates a block and then adds an attribute to the block. This example creates a block with attributes, and then inserts the block in the current space. The modes for the attribute definition are controlled with the following properties: Constant Gives attributes a fixed value for block insertions. Invisible Specifies that attribute values are not displayed or printed when you insert the block.
When this option is selected, you can specify a boundary width for the attribute. LockPositionInBlock Locks the location of the attribute within the block reference. When unlocked, the attribute can be moved relative to the rest of the block using grip editing, and multiline attributes can be resized. Preset Sets the attribute to its default value when you insert a block containing a preset attribute. Verifiable Prompts you to verify that the attribute value is correct when you insert the block.

You should use the one with a FileOpenMode parameter.
Augusto Goncalve , I tried using db. Show 3 more comments. I notice you're trying to add an AttributeDefinition to a Block Reference. Miiir Miiir 1 1 gold badge 8 8 silver badges 11 11 bronze badges.
I did not get you.. In my case blcokreference already has some attributes I need to add new attribute to it. Do I ned to create attribute definition? Miiir, despite the variable name is 'attdef', the variable type is AttributeReference — Augusto Goncalves.
