How To Unblock A Block Reference In Autocad


Identifying block name from the reference becomes bit tricky when dynamic blocks are involved. When users modify the dynamic block, AutoCAD creates an anonymous block first and then creates a reference to it in the drawing. Below code takes care of this scenario and finds the name of the block on selection of block reference. Click Insert tab Reference panel Edit Reference. Find From within the current drawing, select the reference that you would like to edit. If the object you select in the reference belongs to any nested references, all the references available for selection are displayed in the Reference Edit dialog box. In the Reference Edit dialog box, select the specific reference that you want to edit.

AutoCAD .NET :: Error While Changing Block Definition Of An Block Reference

Oct 21, 2013

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.

AutoCAD .NET :: Determine If A Block Reference Of The Block Exist

May 3, 2012

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.

AutoCAD 2010 :: 2011 Windows 7 64 Bit Fails After Update Of MS Dotnet 4

Mar 5, 2012

I updated a working cad station with the lastest pathes. It loaded the new MS Dot Net framework 4. Now Acad crashes if you open it, see below. If you click on an existing drawing it opens and you can work with no problems.
My question is - Is Acad 2011 compatable with the new DotNet 4? The fault module below is DotNet. The old drawings were created using 3.51 DotNet so it looks to me it tries to use the dot net 4 on new drawing.

AutoCAD .NET :: Polyline 3Ds In Block Reference

Jan 11, 2013

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.

AutoCAD .NET :: Change Block Reference Attribute

Mar 7, 2010

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

AutoCAD .NET :: How To Locate Text Near Block Reference

May 24, 2012

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 |.....|

AutoCAD .NET :: Using Block Reference As Point Symbol?

Jun 6, 2011

I create a set of points in a drawing and create each point as a block reference containing the point, text and probably something else. Also I would like to use different symbols for points and each of the symbols is defined as a block definition, and for each point I create a block reference according to the symbol type. The question is if is there any way to 'combine' block definitions/references? I mean, I have common block definition for all points, whis defines somethin common for all of them. Also I have different symbols for each type of points and each symbol is defined separately as a block. But when a final point is created (containing common definitions and type-dependent symbol) I want to have it as a single block.

AutoCAD VB :: Updating Block Reference After Making Changes To Definition

Aug 23, 2013

I have a small vba sub wich changes the color and layer of all entities inside a block. It seems to work pretty well for the majority of blocks, but then if I try that on a dynamic block, the definition is correctly altered, but the references aren't updated...
I know for a fact that the definition has been correctly modified because if I type bedit, I can see the definition is modified. Then, in the block editor, if I save the block, the references are correctly updated.
How to force references to update after I made the modifications inside the definition ?
I searched for methods within the VBA Reference and I tried blockRef.Update but it doesn't seem to have any effect.

When you distribute or archive host drawings (that contain Xrefs) you may want to Save a copy of the host & Bind all Xrefs in it.

  • then you can be sure that all reference data associated with that host resides in a single drawing file.
  • bound Xrefs become a standard block insert in the host drawing and the associated external drawings are no longer required.

Autocad Block Reference Point

Use Bind Bind Types to retain Xref prefixes of dependent symbols.

  • the “|” character in Xref prefixes is replaced with “$#$” where “#” is the smallest integer to make a unique name in the drawing.
  • for example, an Xref layer like T202_5|Solid could generate a layer called T202_5$0$Solid after binding the T202_5 Xref.
  • this is the safest option to use (no risk of duplicate names with different definitions) but results in more names in a drawing.

Use Insert Bind Types to drop Xref prefixes of dependent symbols.

  • this is like Detaching all Xrefs and then using Insert to replace the Xref instances.
  • if you use standards to created your drawings (e.g. layer standards) this may be your most efficient choice.

PRACTICE BINDING XREFS

1) Close all drawings if there are any open drawings.

2) Open the T202_13.dwg in your personal folder.

If you do not see components in this host file you might have forgotten to move the drawing files back into your personal folder.

  • check the My Xrefs folder that you added in the previous exercise (see page 38).

3) Pick Insert + Xref Manager. Select the T202_5 Xref & pick the Bind button. Select Bind as the Bind Type & pick OK to return to the Xref Manager (see the next step).

4) Pick OK to exit Xref.

5) Pick Dimension + Style. Then pick Close.

The Standard and Custom dimension styles were already in the current drawing before the last step

  • the same 2 styles were also in the T202_5.dwg drawing (this happens often when you work with drawing standards)
  • the T202_5$0$ prefix appears before the same two dimension style names because you used the Bind Bind Type.

You would see this prefix for many other symbols in this drawing

  • such as Blocks, Layers, Text Styles and Linetypes.

» 6) Pick Format + Layer and observe the layer names with the same T202_5$0$ prefix. Then pick OK to exit Layer.

7) Pick Insert + Xref Manager. Select the T202_6 Xref and pick Bind. Select Insert for the Bind Type this time and pick OK. Pick OK to exit Xref.

8) Press the F2 function key to observe the command line history then pick F2 to return.

This time all named dependent symbols were bound without the prefix that was used before the T202_6 Xref was bound.

  • there were duplicate blocks names but AutoCAD ignored the definitions of these blocks.
  • definitions of symbols in the current drawing are used when there are duplicate names.
  • this is not likely to be a problem when you use drawing standards and template drawings to create new drawing files.

9) Pick Insert + Xref Manager. Press & hold <Shift> while you select the remaining Xrefs. Then pick Bind. Select Bind as the Bind Type and pick OK to return. Pick OK to exit Xref.

You can easily select ALL Xrefs in the current drawing and pick the Bind button to bind all Xrefs in one step.

  • you can select more than one Xref by using the <Shift> key.

If you are binding Xrefs only to distribute drawings to others you might want to Save the host with a new name first.

  • you cannot convert bound Xrefs back to true Xrefs again so you should Save a copy of the original host before binding anything.

How To Unblock A Block Reference In Autocad

You can also use the Xbind command to bind individual named dependent symbols to the current drawing.

  • for example, you could Xbind a dimension style from another drawing so that you could use that style in the current host.
  • but with the introduction of DesignCenter in AutoCAD 2000 there are now better alternatives to Xbind.

10) Save your changes to the current drawing & Close the file.
