I get a block reference (has attribute) from other drawing as code follow:
Public Sub GetBlock_Info() Dim blockName As String = "test" Try Dim doc As Document = Application.DocumentManager.MdiActiveDocument Dim doclock As DocumentLock = doc.LockDocument() Dim ed As Editor = doc.Editor Dim ofd As New OpenFileDialog("Select Drawing", Nothing, "dwg; dwt", "ATS detai drawing", Autodesk.AutoCAD.Windows.OpenFileDialog.OpenFileDialogFlags.DoNotTransferRemoteFiles) Dim dr As

I'm trying to change block the definition of an block reference.
I did something like this:
blockreference.BlockTableRecord = newBlock.ObjectId;
In most cases this works well. However I found a case that it not work as well. When I try to change the definition from a new block that I have created in my test DWG, it disappears from the model.

I have a block: “Block_A”. I am trying to determine if a block reference of the block exist.
Currently I would iterate every block Reference in the Block Table, and then dig deep into each block ref . . . . .
I was wondering if I could just take “Block_A” and see if it has reference and where the references are. Perhaps this is just wishful thinking but I was hoping for a faster way to obtain the references then to iterate thousands of blocks in each table record.

Drawing contains a block with "BlkName". I want to insert blockreferences of this existing block using .Net. All shows how to insert a new block and then use the BlockID returned by the insert function. In my case I only have the block name and there is no Block id. How to get it or how to create a block reference of an existing block?

I want to create an application that intensively uses dynamic blocks, cross checking any new or changed block entity with existing ones.
It needs to be almost instantaneous but the only way I know will be impractical.
Looping through the property collection of each block reference, searching for each parameter then checking for a match.
Is there some sort of database functionality I can use to quickly compare block information?

When I create a sketch block, there is a description area. After the block is saved, how can I see this information again? If I right click on the block in the browser, I cant find it anywhere.

I've argued this repeatedly with the powers that be at my small company and they're set on some old methods that I'm trying to figure out how to make happen.
We often have weldments where we do an assembled view on page 1 and balloon it and have a parts list. Pages 2-4 will be the details of the welded parts. On page 1, I bring in the "Title" and "Subject" fields from the assembly iProperties.
Here's the tricky part. On pages 2+, I don't want to bring in those two fields, I want to bring in something different. Is it possible to differentiate like that?
Second part of the question: is there a way to pull the balloon item number from page 1 into a field somewhere on following pages? For example: page 3 may show the details for "item 2". Can I bring the value of that balloon (item 2) into page 3 somehow?

I am not sure this is even possible, but could I use some sort of invisible block attribute data and everytime I insert it into a drawing (I use the same block multiple times within a drawing) it would autopopulate fields in a table. For example I have a smoke detector symbol I insert, I also have a specific address associated with every single detection symbol I insert into a drawing, would I be able to attach data such as what type of detector it may be and have the address and type automatically populate in a table everytime I insert my block into a drawing?

I am working with a set of dynamic blocks, each with a block table that provides a drop down for the user to alter attributes from. My goal is to be able to update the block table using VBA to push data from an excel file. I do have import/export code that will update block attributes, but I am not sure the functions that would access the table properties.

I was curious, when creating multi sheet drawings, how can I place different information in the title block on each drawing?
Example, 2 pages, Description on page 1 = PAGE 1 DESC, by default this same description will show up on all subsequent pages. How do I get page 2 description to be different?

How do you make the information in your titleblock transfer to all pages?
I am sick of going on each page in paperspace and re-editing the same minor details.

This is the command line responce I get when i attempt to enter text. All teh numeric expressions of all my dimensions have been replaced with a backslash. Along with all text including infomation on the attributed title block.
I have exhausted my options for figuring it out, do I need to reload the program? is there a restore default option? ( I haven't found one yet) I am running 2011 LT

We just moved the Autocad LT installation for one of our users to a new computer and now when opening certain documents, we get the below error. The error didn't originally occur on the old machine, but after re-installing it on that machine, we get it there too. Is there a way to clear the error or find out which plugin we are missing? We have tried installing the plugins on the autodesk website, but weren't able to fix the error.
System information:
Autocad LT 2011
New machine OS: Windows 7 (64 bit)
Old machine OS: Windows XP (32-bit)
Error message:
Proxy Information
The drawing you have opened or referenced contains custom object created by an unavailable ObjcectARX application. You do not need the original application to display proxy representations of objects that were saved in the drawing. However, many manufacturers, including Autodesk, provide object enablers that also allow you to edit these custom objects.
Visit the AutoCad LT Object Enabler Assistant web page to locate Autodesk object enablers or contact the software publisher about object enablers for other applications.
Note: If your computer has internet access, verify that Check Web for Live Enablers is selected in the Options dialog box on the System tab to have AutoCAD LT automatically search for the Live Enabler website for the appropriate object enabler.

I have a weird problem with exploding block reference with vb.net as follows.
When I use BR.explode(DBObjectCollection), and append the entities in the object collection to model space,
the 3d Polylines inside the block reference do not get appended and I do not get any kind of error. The reason for this eludes me as of yet. (remember, simple polylines and lines and other objects do get appended to model space)
When I use BR.explodetoOwnerSpace(), the block reference explodes as it normally is expected to, but then I have no way to collect the objects from the exploded BR.

I'm working with two different drawings to import Layers for Lot Grading and when I'm importing the Block Reference from the origin file, it's setup as Linescale 0.5, but when I import into my regular basemap, which is setup for Linescale 1, the text size is double what it should be.

I'm trying to write a vb script to extract information from the CAD drawing. While testing, i found that for some drawing blocks, the corresponding AcadBlockReference Rotation returns 1.57, but when i look at the actual drawing, block properties, the rotation is 0.

I have a block reference in a dwg that is a like a form, for example:
Written By: Diogo
Author: Diogo
Date: 13-07-2012
State: Check-in
In autocad this is a block, and on the attributes of the block reference I only can edit State and Author, and i would like to get all values. Because i want to fill those values of Written By, Author, Date and State by code. I can reach the attribute collection of the block but i only can see the State and Author.

I have a drawing with many block references on it and they have some attributes.
I know how to find the block reference witch the attribute value, and even change it but I don't know how to select it once I have the object ID of the block.
How can I do the selection without asking the user to select it?

I wonder if this can be done. i have a number of blocks which have labels to them i.e. JW1, JW2, JW3 etc. which corresponds to the block name. Is it possible to have the label automatically referenced to the block name so if i change the block name to JW10 the label within the block changes to JW10 as well.

I have an issue regarding nested entity.
I have a nested entity block reference. In this entity I have three blocks. if I change any of the block reference attribute definition in the nested block reference then it is changing the original block itself.
Actually I am getting the handle of the selected block reference in the nested Entity. and change the attribute reference later. but it is making change in the block itself and other block reference too.
Here is my
static public void CONTACTS()
{
Document doc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;
Editor ed = doc.Editor;
string contactName = string.Empty;//to hold contact name, from xdata

I have tried to use intersectwith to locate text (MText or DBText) near a block reference. Some times it works and some times it does not. The hard part for me is understanding why it occasionally works when most examples are just duplicates with modified text and attributes.
My block reference has 4 attributes to the left (Right Justified) of a circle and 2 attributes inside the circle. The text objects are used by some CAD operators instead of the upper 2 lines of attributtes. (Guess they dont know how to modify attributes) I want to locate these texts and insert text into the corresponding attribute.
Block Reference:
Att 1 |'''''''| <-- CAD User will insert a txt over Att 1 and Att 2,
Att 2 | | <-- both attributes are usally left blank or contain a space
Att 3 | |
Att 4 |.....|

Is is possible to get the block handle from an attribute reference? I get the attribute reference from a previously stored attribute collection. I did try attref.BlockId.Handle.Value.ToString(), but it gives a different value, not the block's id.
