I 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.
So 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.
Do we have any way to sum attribute value (integer) of many blocks fast?
View 8 Replies View Relatedmy 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)?
I 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.
I 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?
I have a question regarding object overrule.
Simple example, when overrule Line entity to draw three entities Line, Text, Circle when selecting overruled Line is it possible to identify what object have been selected (in this example it could be Line, Text, Circle).
I want to change display of custom object using overrule.
First I made a class implements from polyline.
class BoundaryPolyline : Autodesk.AutoCAD.DatabaseServices.Polyline { }
Second I made a polylineJig to draw my custom polyline(BoundaryPolyline).
public class PolylineJig : EntityJig { public PolylineJig(Point3dCollection p3ds) : base(new BoundaryPolyline()) { ... } ... }
And then add overrule on BoundaryPolyline to change display of it.
Overrule.AddOverrule(RXObject.GetClass(typeof(BoundaryPolyline)), mydrawOverrule, false);
But when I loaded dll, fired overrule and redraw. All polyline display were changed.
Then I found that 'RXObject.GetClass(typeof(BoundaryPolyline)' was return 'Polyline' but not 'BoundaryPolyline'.
How to overrule on custom object.
I 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?
My 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.
I need to use the Handle of the cloned object during a DeepClone override but AutoCAD shuts down when I try to use it.
This is the best I can think of but it still boots me out when I try.
Public Overrides Function DeepClone(ByVal dbObject As DBObject, ByVal ownerObject As DBObject, ByVal idMap As IdMapping, ByVal isPrimary As Boolean) As DBObject Try Return MyBase.DeepClone(dbObject, ownerObject, idMap, isPrimary) Catch Finally CompileCloneObjects(dbObject.Handle.ToString, MyBase.DeepClone(dbObject, ownerObject, idMap, isPrimary).Handle.ToString) End Try End Function
If I add a DeepClone overrule on Initializeing a drawing it stops my block Jigs from showing correcly. I get a line drawn instead of the block. Other overrules I have used don't cause any problem.
By excluding the overrule from the initialize event it works fine.
I can remove then add the DeepClone overrule before and after the jig and it works ok but I really need it active on drawing startup.
Hit the brick wall again.
Ideally I don't use an overrule. All I need to do is understand what objects are being cloned before, during or after a clone operation but can't figure out the idmapping thing.
I am about to write the function using Overrule API to temporary override object’s colour to ByLayer for all entities in the drawing.
At this moment I just have simple class for testing (just to check if it is possible) and so far I can see problem with complex entities.
Entities such as Line, Polyline even BlockReferences work fine but complex objects like HATCH, MTEXT and LEADER do not change colour as set in SetAttribute method.
Below is simple class I was testing.
public class ByLayerColorOverrule : DrawableOverrule
{
public override bool WorldDraw(Autodesk.AutoCAD.GraphicsInterface.Drawable drawable, Autodesk.AutoCAD.GraphicsInterface.WorldDraw wd)
{
base.WorldDraw(drawable, wd);
return true;
}

My goal is to write a Drawable Overrule, which would change the entities color to dark gray, except when they are on a specific layer. For closed-only curves in this layer, I want to add a semi-transparent hatch.
All works great, until user moves the mouse over this hatch : AutoCAD throws a fatal error and closes. I've no exception in debugger...
When I remove the code concerning the hatch, I've no error at all.

Planning to overrule some of sub entities in a block. Let's make it simple . All lines and attributes in block should be circles and original block should not be seen. I came up with below code.
The code reacts differently if I remove

and my goal is not to show the real block. Just showing whatever is overruled.

Using AutoCAD 2013 and TOL command to generate feature control frames. We set our lineweights based on layer assignments.
Problem is that when printing, AutoCAD seems to randomly assign a lineweight to the feature control frames. It can vary from what it's supposed to be (such as lineweight set for the dimension layer) or thicker than even what the object lines are set at. Seems to pick a random linewieght at time of printing for these elements (just the boxes, not the symbols/text itself).
Is there a setting we should be defining somewhere to force it to follow the lineweight of the layer that it has been assigned to? Known bug?

This has been happening intermittently but now seems to be permanent. When I slect the Multiline tool, click to place the text box, then click to place the other corner the box ignores the size I set and snaps to as wide as the screen and one line high. It does this in several different drawings so it is not native to one. If I enter text and deselect I can adjust the handles and alter the text.
I have attached a screen shot to show. It doesn't matter how close or far I am zoomed in on the drawing.
For what it's worth I do not like the way the ribbon panel controls handle text, it usually takes multiple tries to get it to change the text height. I usually resort to using the Properties flyout but that adds mutltple steps to the process.
