AutoCAD .NET :: How To Check BlockReference
Jan 3, 2013So i have 3 file DWG :
3.dwg : is a plan 'archi'
2.dwg is a plan with only décoration.
1. dwg is a plan with only the water.
i have this structure in my file (1.dwg) :
1.dwg
---> 2..dwg
---------> 3.dwg (this file is a Xref of 2.dwg)
--> is the blockRefecence (XRef).
Dim CollXref As New ObjectIdCollection Dim mydb As Database = Application.DocumentManager.MdiActiveDocument.Database Dim myTrans As Transaction = mydb.TransactionManager.StartTransaction ' Dim doc As Document = Application.DocumentManager.MdiActiveDocument
[Code] ......
So i don't want to add Id of a Xref From a Xref. (In my example i want only ObjectId of the 2.dwg not 3.dwg if i launch this code on 1.dwg.
AutoCAD .NET :: How To Get Block Description Through Blockreference
Dec 28, 2013my block is a anonymous block with a blockname like "*uxxx", but,but it is not a dynamic block.
how can i get the block description through the blockreference(insert)?
AutoCAD .NET :: Overrule Control In BlockReference?
Jun 26, 2012I am working on simple WorldDraw overrule where lines and polylines are displayed with little cross. Size of cross is related to view size.
Everything works fine except blocks and Xrefs. If they are scaled then crosses are scaled as well.
I know how to get entity owner ID but it refers to BlockTableRecord only not to BlockReference.
AutoCAD .NET :: Modified Event Of BlockReference Causes Crash
Dec 11, 2012I have a group of classes that essentially implement the Model View Controller pattern. The view is a custom control contained in a PaletteSet. The Model is a class that wraps the ObjectID of a given block. I've used these classes to create a replacement for the Properties tool in AutoCAD (2011). Basically the UI can be used to edit the properties of a Dynamic Block. But I apply my own rules and behaviors to the UI.
I had no problems until I added support for the View to be updated when the block is modified (say by dragging to increase a length property). To do this I handle the Modified event of the block. After the block is modified, some rules are evaluated. If the rules result in changes to the block's properties, these changes are applied. This last part is where I'm having trouble.
When the "Rule Evaluation" code is invoked because of changes to the view (WinForms Controls), I am able to update the block's Properties using the following code without issue:
Public Shared Function SetParameter(ByVal BlockID As ObjectId, ByVal ParameterName As String, ByVal Value As Double) As Boolean
Using dl As DocumentLock = Application.DocumentManager.MdiActiveDocument.LockDocument(DocumentLockMode.ProtectedAutoWrite, Nothing, Nothing, True)
Using myTrans As Transaction = BlockID.Database.TransactionManager.StartTransaction
Dim myBRef As BlockReference = BlockID.GetObject(OpenMode.ForWrite)
For Each myDynamProp As DynamicBlockReferenceProperty In myBRef.DynamicBlockReferencePropertyCollection
If myDynamProp.PropertyName.Equals(ParameterName, StringComparison.OrdinalIgnoreCase) Then
myDynamProp.Value = Value
myTrans.Commit()
Return True
End If
Next
Return False
End Using
End Using
End Function
However, when this same code is invoked as a result of the BlockReference Modified event, AutoCAD completely crashes the momment the transaction.Commit() method is called. I've attempted to catch the exception causing the crash and role back the transaction, but AutoCAD simply exits and displays the error (Error handler re-entered. Exiting now.) and no exception is caught. Note that I do not use the BlockReference instance passed to the Modified event handler. Instead I store an ObjectID instance elsewhere which is consistently used to read/write the block.
Is there something I must do before commiting a transaction when using the Modified event of BlockReference? I checked, and the same "Main Thread" is executing whether the code is invoked from a UI event or the Modified event. I tried calling the Close method, which is attributed as Obsolete, on the BlockReference object before executing the transaction without any success.
AutoCAD .NET :: Inserting BlockReference With AttributeReferences From Another Drawing
Apr 24, 2011I need to insert Blocks with Attributes and its values from another drawing into the active drawing. I am not sure if the way I am doing it is correct. I am having problems with the transactions, one for the source drawing and the other for the active drawing. I had a few eviolations problems. It seems that I have to close the transaction of the source drawing before I can access the active drawing and the other way around.
Since it is a BlockReference with AttributeReferences and its values I firstt opened the source drawing on a side database withing its own transaction and went through the ModelSpace TableRecord until finding the BlockReference with the correct AttributeReference value. Then, I had to store all the Tags and TextStrings on an array because I could not access the active drawing without closing the source drawing transaction.
If the BlockDefinition exists on the active drawing then I only have to create a new BlockReference with the AttributeReferences and update its TextStrings with the values stored on the array. All of this withing the active drawing transaction.
If the BlockDefinition does not exist on the active drawing I could insert it from the source drawing side database ONLY within the active drawing transaction. I have to close the source drawing transaction first.
Now, is there any way of doing this that won't require switching transactions? Is it possible to find the BlockRefence on the source drawing from the active drawing transaction?
AutoCAD .NET :: Blockreference Position And View Coordinate System?
Aug 5, 2013I have rotated my view about 15 degress (just for this example).Now I prompt user to select the point, which is also an insertion point of the block.
So we have:
- selected point: X=0, Y=294, Z=0;
- insertion point of the block: X=0, Y=294, Z=0
(this is what I have in properties list or when I execute LIST command).
Now in my
ed.WriteMessage("
Base X: " + basePoint.X.ToString()); ed.WriteMessage("
Base Y: " + basePoint.Y.ToString()); ed.WriteMessage("
Block X: " + blkRef.Position.X.ToString()); ed.WriteMessage("
Block Y: " + blkRef.Position.Y.ToString());
This gives me:
Base X: -2.89976376244283E-14 - OK
Base Y: 294.058394637539 - OK
Block X: -76.1079129044681 - BAD
Block Y: 284.038597817502 - BAD
My question - why blockReference position is different that it should be?
AutoCAD .NET :: Selecting Nested Entities And Inheriting From BlockReference
May 1, 2012My primary goal in this exercise is to select a nested polyline within a block and have access to its grips. I'm still not even sure if it's possible.
However, before I'm even getting to that stage I'm hitting some problems. I have some custom objects which all in some way or another inherit from BlockReference:
BlockReference
-Derived Abstract Class with common attributes
-Derived Concrete Class1
-Derived Concrete Class2
-Derived Concrete Class3
I insert instances of my derived concrete classes using jigs( Class2 for example is created using a polyline jig). However, when I select the block generated from it using a PromptSelectionResult, it returns a BlockReference, not the derived concrete class, not the derived abstract class.
When I try and cast that as the correct class type I get an error telling me I can't cast from the Base class to any of the derived classes.
So, firstly, why is it returning a BlockReference when the object I'm clicking on is an instance of a type that indirectly inherits BlockReference? And is it even possible to gain access to a nested entity's grips? I followed post here: [URL] .... but it doesn't give me what I need.
I've tried ed.GetNestedEntity and the AllowSubSelections property of PromptSelectionOptions and had little joy.
AutoCAD VB :: 2011 Batch Convert Field Attribute To Text Attribute In Blocks Using VBA
Jun 3, 2011I've got hundreds of files to convert.
In VBA, how can I batch convert field attributes in blocks to text attributes while retaining the blocks? Is there a simple way to univerally convert them all at onceusing VBA? The plotted values for the fields must be retained, too.
Explode will not retain the value of the field.
Burst will not work as it explodes the blocks as well.
You can right-click on the field and slelct "Convert to text" from the RCM. So I know that the process exists within CAD, just need to batch the process for a quantity of DWGs at a time - in VBA.

AutoCAD Visual LISP / AutoLISP :: Convert Attribute Tag Into Attribute Value?
Dec 8, 2011Background: Someone exploded an attribute block and copied it hundreds of times throughout a project, each time changing the Attribute Tag to match the Value they expected to appear in their drawing. The drawing must be xrefed, so the attribute definitions do not appear.
(There is only 1 attribute in the block.)
Proposed Solutions:
1:AutoLISP routine which copies Tag data from Attribute Definition into Value of Attribute Block:
Prompt-Select Attribute Definition
Copy Tag data
Prompt-Select Attribute Block
Paste data into Value
(Allow repeat to speed workflow)(*PREFERRED*)
2:AutoLISP routine which copies Tag data from Attribute Definition into Default Value and creates a new Block:
Prompt-Select Attribute Definition
Copy Tag data
Paste data into Default Value
Create New Block
(Select Multiple Objects)(Creates tons of new blocks which are messy)
AutoCAD .NET :: Attribute Reference Text String MText Attribute
Mar 16, 2012I 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?

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.

Jun 15, 2013I want to copy attribute values. I'm making a catalogue of all the reinforcements in my drawing so I need to name those reinforcements. So what I want is to make a string of text that I don't need to totally modify everytime. Something like this:
Amount of reinforcement bars - 5
Diameter of the reinforcement - 12
Division of reinforcing bars - 100
Reinforcement bars: 5-T12-k100
So the only attributes I'd edit would be the first three not the last one. So how can this be accomplished?

Mar 20, 2012How I would be able to grab the block constant attribute by searching via tag.
e.g. block has a constant attribute 'Color' with value of 'red' and I wish to attain 'red'
I am currently obtaining non constant attributes using:
Dim attRef As AttributeReference = DirectCast(tr.GetObject(attId, OpenMode.ForRead), AttributeReference)
and grabbing the '.textstring' when looking at the '.tag'
How do I go about this with similar logic but pointing to constant attributes? I have tried searching thoroughly and almost all results for me were in VBA.
