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

select all blocks on certain layers in a drawing, check attribute CIRCUIT in each block if it starts with MS then attribute CONTROL = switched. I hope thats clear enough the way
(defun c:control() (graphscr) (Setq sc (ssget "X" '((0 . "INSERT")
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?
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.
What I really want to do is on our fire alarm blocks we have 3 different attributes one for the address, the candela and one for misc info. I want to make an attribute that takes the number from the candela (15,30,75or 110) and change a different attribute to a value depending on which candela we use (such as 15=.078, 30=.113, 75=.195 or 110=.259). But I don't want the .078,.113,.195,.259 to print out on paper, I want to export block information excel file so I can add up all values.
i have tons of column tags but wants to change the distance between column size and the circle and make the font smaller. I can do this individually but can't do one by one..... is there any way i can adjust all by one command or one magic touch?
How to access the BTR, read and write BRef, attDef, AttRef etc. But this has me stumped. There are a few different examples but can’t find anything that works and don't know why.
I have inserted a block in modelspace, I have the BlockRefID and now want to change its attribute values. This finds the attributes tags but doesn’t write the sValue. Why it isn’t writing the value to the block.
Public Sub ChangeAttributeValue(ByVal BlockRefID As ObjectId, ByVal sTagName As String, ByVal sValue As String)
Dim doc As Document = Application.DocumentManager.MdiActiveDocument Dim db As Database = doc.Database Dim tr As Transaction = db.TransactionManager.StartTransaction() Dim br As BlockReference = DirectCast(tr.GetObject(BlockRefID, OpenMode.ForWrite), BlockReference) [code]........
I am using M Text Attributes to store imperial lengths in the drawing, feet inches and fractions (stacked). When I read back the Text String property which, is the M text Attribute.Contents parsed, I am having problems because the parser does not add a space between the inch and the fraction. So, is there any setting that could be used to tell the parser to add the space between the inch and the fraction?
I have a problem: There are a lot blocks in my DWG with 3-5 Attributes. I change the Values of the attributes in the .Text String but they aren't set as default values of the block attribute. Now i want to set the actual value as default / initialize value of the attribute without entering every time in the block editor
with the following code its possible to change the text string. I can set the attribut.textstring as default value?
Public Sub changedefault() Count = ThisDrawing.ActiveLayout.Block.Count For Index = 0 To Count - 1 Blockstring = ThisDrawing.ActiveLayout.Block(Index).ObjectName [code]......
I just want to change colors for all objects in current model space. But this command also changes attributes/blocks definitions (I mean, any new block which I insert has the color that I specified previous).
What I am trying to do is grab the value of the owner tag (of which there are four), and use that value to determine which layer to place it on. What it seems to be doing is hanging.
creating a block with attributes. I did manage to get my block set up and inserted in a dwg, but I am unable to change the "value" of any attribute. Unless I click on the "..." button next to the value field.
I change a block's attributes programmatically using thisfunction I created:
private void UpdateAttributes(Database database, Detail det) { using (Transaction tr = database.TransactionManager.StartTransaction()) { //Grab the BlockReference the detail refers to. BlockReference block = (BlockReference)tr.GetObject(det.ObjectId, OpenMode.ForRead); //Iterate over the Attribute ids. foreach (ObjectId [code].......
You can ignore the Detail and Detail Attribute objects as they are also user-defined. Also note that this function expects the database to be currently open for working on.
Everything in this function works fine, but there is a strange quirk that becomes noticeable only when I use this function to edit an attribute that has its "Invisible" property set to "No".
Below, is the original block that is edited via this function:
As you can see, the block has a number with 4 digits (for our purposes, call this the Block Number).
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've had a simple lisp I've been using for years that suddenly disappeared. It required that you identify a block name, tag name, and the value that you want the tag to be. All of this is performed via command line, so it is scriptable. Since I lost it, I've been experimenting with -attedit. This command comes frustratingly close to what I'm looking for, except it only appends an existing tag, or replaces a specific string within the tag; I can't get it to replace the entire tag, regardless of its value.
1> Any lisp routine that does what I describe? or 2> How to make -attedit replace a tag value without regard to what the value currently is (like a * wildcard)?
Is it possible, via whatever methods (lisp?) to be able to have a premade block with an attribute and insert it into a drawing then assign a value to it by selecting another existing block in the drawing and using one of its own attribute’s values?
For example, say I have a block representing a telephone and it had an attribute called "PhoneNo" and I inserted it into a drawing showing an office floor plan that had blocks in each office space that are telephone junction boxes with attributes "PhoneExtension". I would like to be able to autocomplete the entering of the “PhoneNo” data by selecting one of the telephone junction boxes in the drawing and using its attribute’s value.
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.
I have an existing title block a few text attributes, to which I wish to add a watermark. I have added it in the block editor as a normal attribute, with the same details as the other attributes that work, only a different tag name. It has a default value, "DRAFT" and is tagged "WMARK". It works fine in the Block Editor, and If I test the block I can edit it to display whatever I want, but if I save the block and open it from Autocad proper, the attribute is not in existence, either as a default value, or editable from block properties, attribute editor or title block editor, whereas all of the other attributes are there. I have used BattMan to verify the settings of the attribute, and the only difference is that the others all have "L" in the "Modes" column, but I think that means that their position is "locked" whereas my new attribute is justified "aligned" therefore cannot be "locked" (This is some assumption on my part, as the documentation on the "Modes" column is almost non-existent). I cannot afford to waste much more time on this issue, as the boss is breathing down my neck, but editing watermarks on every drawing after every revision is frustrating, when it could be an attribute that is editable from the title block editor.
I need to match few attribute values from one block to different block. I download a lisp file called; ca.lsp which can match the single attribute value. I modified it for more than one attribute value matching. It is ok but still wish to overcome two issues for batch prcess
1. picking up the blocks by selection
2. click the alternative block numbers of times to match the numbers of attribute values I needed.
How to modify this lisp I can run it by block name selections instead of picking selection which enable me to run batch process for numbers of drawing? That will be good...
Lisp & Demo file attached (Match attribute value, A, B & C to Attribute 1, 2 & 3).
Is there a way that I can create a block with text ('A') and when I insert the block and populate the block another block block will update also? I am wanting to create a block for x-sec flags, and detail callouts that update their detail titles.
Drawing 1 : Contains tree blocks that have a specific scale dependant on the tree size
Drawing 2 : Contains a block with just a point and attribute data about the tree (name, size etc.)
This block is approximatly at the same location as the tree block (0,1 m precision)
Problem I want to join these two items together. In other words, in the tree block that is scaled correctly i want the attribute data with the name, size etc. These blocks don't have a corresponding unique number or something like that.
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 just opened up a project Sheet Set that i haven't worked on in a while, and all of my layout pages have a series of "#" in place of the fields. For example, the name of my viewport should read "Head Detail", which is the name given to that view in the Sheet Set Manager, but instead reads "##############". This also happens with my view numbers, callout bubbles, etc.
However, the information in my title block is still intact. For example, the Project Name, Client Name, Page Number, etc. all read the correct values.
I tried opening the drawings in Reference Manager, but I see no alerts or errors. I have had this happen before in previous versions going back to at least 2010, but they have always been small projects and I just recreated the views and callouts. This is a large project however, and redoing this will cost hours, if not days of extra work.
In examining the fields, it seems like the problem fields are those defined by the SheetSetPlaceholder Filed Name, and the Placeholder type is irrelevent; they are all broken. For other Field Names, for example CurrentSheetNumber, the references still work.
In the blockeditor I can change the draworder so the attribute is partly under some lines. But the draworder in the blockeditor of the attribute doesn't work in the normal modelspace; the blockattribute is allways on top.
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.
