AutoCAD .NET :: How To Get All MLeaders Even In Blocks Nested Ones
Aug 13, 2013
I need to EnableFrameText to all MLeaders in a drawing, I also want to get the MLeaders who are nested in Blocks automatically...
I started this way but It just works fine with the Mleaders in Modelspace or if I open the Blockeditor to edit Mleaders nested in a Block...
I know I'm not going to "deep", maybe I need an other Transaction, or thirst open each Block to edit... not right sure...
my example:
//Ändert leider nur die MLeader die nicht in einem Block sind....
[CommandMethod("MLeaderIterator")]
public static void MLeaderIterator_Method()
[Code]....

I'm attempting to have the user select mText from a nested block within a block and then copy the nested block to model space out of the block. I'm able to change the mText successfully, but when I attempt to get the nested block it is not in the list of GetContainers() it only contains the block in model space and the model space block. The nested block is missing in the list. I'm using AutoCAD Civil 3D 2013.
Here is the code to select the mText object which works correctly.
Sub GetNestedMtext() ' Have the user select an object. Using the prompt provided. Dim ed As Editor = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Editor Dim entopts As New PromptNestedEntityOptions(Environment.NewLine & "Select a mText in block to replace: ") entopts.Message = Environment.NewLine & "Select a mText in block to replace: " Dim ent As PromptNestedEntityResult = Nothing Try ent = ed.GetNestedEntity(entopts) Catch ed.WriteMessage("You did not select a valid entity") End Try If ent.Status = PromptStatus.OK Then CreateDuplicateBlockInModelSpace(ent) End If End Sub
Here is the code that attempts to get the nested block which is missing the nested block.
Private Shared Sub CreateDuplicateBlockInModelSpace(ByVal ent As PromptNestedEntityResult) Try Dim containerObjIds As ObjectId() = ent.GetContainers() Dim blkToExtract As BlockReference = DirectCast(containerObjIds(1).GetObject(OpenMode.ForRead), BlockReference) Dim blkToPlace As BlockReference = blkToExtract.Clone() Dim doc As Document = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument Dim db As Database = doc.Database Using tr As Transaction = db.TransactionManager.StartTransaction Dim acBlkTbl As BlockTable acBlkTbl = tr.GetObject(db.BlockTableId, OpenMode.ForRead) Dim acBlkTblRec As BlockTableRecord acBlkTblRec = tr.GetObject(acBlkTbl(BlockTableRecord.ModelSpace), OpenMode.ForWrite) acBlkTblRec.AppendEntity(blkToPlace) tr.AddNewlyCreatedDBObject(blkToPlace, True) tr.Commit() End Using Catch ex As System.Exception End Try End Sub
Is there another way I can get the parent block object for the nested object?

Here is the problem with the process put simply:
Start with a new drawing Drawn a rectangle. Place a block which has an attribute with a number at each corner. ie. 1-4. Convert all objects into one single block. (the attributes become nested). If you use data extraction and retrieve the attribute number, position X and position Y, and output to a table the information displayed is correct. HOWEVER, if you rotate the block and update the link the coordinates become incorrect? This seems to be an issue with nested blocks?

Autocad 2011
wondering if its possible to turn off lines inside of nested blocks.
When we tried to do this inside a heavily layered and blocked drawing, it seemed to make the file unresopnsive, unloadable, and general "autocad freezing" issues. We Reconsitituted the entire file from the ground up and found that by NOT turning off these lines inside of nested blocks (ceteris parabis) the file works fine.
We like to turn these lines off becuase different teams are working on different parts of the drawing and we like to focus on one section by turning the other off. Is this possible? Is there a better way to do this?

I have an XREF that contain block inserts sometimes nested 2 or 3 levels deep. Given the block names, is it possible to find and translate the insertion point of the nested inserts to the current World UCS?
Ideally I would give a routine the block name and it would scan the current drawing and return a list of the translated insertionpoints>

I have a .dwg file which contains numerous blocks (70 or so) and they all have unique names.All these blocks have nested text.
I want to edit the attributes of all the text, in all these blocks, such that they assume the same text style, text layer and colour.
Obviously, with so many blocks, I want to avoid clicking on the text and editing the attributes individually.
I tried a lisp file called ATcolour.lisp, but even this is very time consuming.

I am drawing a block that containes a number of other blocks which I want to control parametrically. For example. In one block, I have set the diameters of a circle restricted to 10 and 12-mm. I have a second block that also contains the circles which have similar restrictions. I now want to control the diameters of the circles from a single source - similar to shared parameters in Revit. Am I able to share a global parameter between blocks?
Eventually, I want to control a 2D drawing from a table only. Should I be using .Net or AutoLisp for this.

The 2D drawings I am working with were exported from 3D REVIT files to 2D AutoCAD files. There are several XREFed drawings that are both mechanical and architectural from the original REVIT files that for whatever reason, the block's line weights came over with line weights of 70 in those blocks.
When I plot, the objects are a blur with the line weight so high. I tried using the command "setbylayer" but that didn't work since nested blocks still had lineweights of 70. Is there a VBA or LISP routine to run through all the blocks (including nested) that can change the line weights to a given number?

Basically the question is if it is possible to explode families similar to blocks in AutoCAD.
Here is an example: A Family made for placement in the model has 2 nested families. Once placement is done is it possible to eliminate the initial family so only the nested families remain? All the parametric values can go away that’s fine and the nested families are also shared if that matters.
Since I come from AutoCAD and started with Revit v2012 it is basically like a block within a block which you could just explode so much until only lines are left.

I have an old project where the mleaders were all created in WCS and aligned to it for a preliminary plan set. Now that the plan has progressed to CDs (over a year later) they have rotated the views to a new alignment for the final plans. I'd love to not have to re-do all my mleaders in the new UCS to match the new alignment. Any way to update existing mleaders to follow a new UCS?

I'm finding Mleaders with Mtext don't seem to play well with command calls. All works fine until one tries to enter the mleader text. Before testing this, be sure your mleader style is set to use mtext. I recommend starting the leader with the arrow first.
Compare this mleader's text entry behavior in this basic lisp command call:(command "_.acad_dim.mleader") with the following routine that relies on an open ended command prompt (useful if you want to add more commands after calling the mleader command):
(defun c:mlx (/ cc_echo)
(prompt "
Example showing mleader mtext misbehaving")
(setq cc_echo (getvar "cmdecho"))
(setvar "cmdecho" 1)
(command "_.acad_dim.mleader")
[code]...
With qleaders, the leader and text are separate entities.

Reason: The Mleaders are causing issues with the viewing software that we have to use with our drawing management program.

I select all entities via Editor.SelectAll() method, but the nested entities (inside Blocks) are missing. Do I have to resolve them by iterating through all blocks afterwards or is there a Prompt Selection Option that can be set?
I don't want the user to select the entities, instead I loop through the whole drawing.

Im trying to figure out what I can do differently in my code to have it show the newly placed text immediately after choosing an insertion point. Im guessing it has to do with a nested transaction and my loop, but Im not sure how to fix.
The code below is to label the layer of a selected entity. If in paperspace, label in paperspace and if in modelspace label in modelspace. Ive been testing this on the "blocks_and_tables_-_imperial.dwg"

I am trying to get either location, insertion point, or center of an entity that is inside of a block. I'm getting subentity using the Editor.GetNestedEntity. I create a FullSubEntityPath for highlighting, that works well, and I have looked at using GetSubEntityGeometricExtents using that same subentitypath, but not having any luck, I can't seem to find any documentation on using that method.
I know I can get the location of the owner, then calculate the location of the entity based off of that, but I'm looking for an easy way now, if that don't work out, I can do the lengthy approach.

There are blocks in the drawing, each containing several nested entities. Need a command which would find all the nested entities which got into the selection area provided by user (not necessary to select entities, just get the ids). GetNestedEntity() does what I need but for a single entity only.
Selection of 'Trim' command does exactly what I need. How could I achieve the same behaviour?

My question pertains to layer colors from xrefs that have other xrefs nested inside them.
When I get xrefs from the architects, I get a building layout, RCP, space layout, etc. I tie all these together into a single "architect base" xref so I don't have to attach 4 xrefs to each new file I create. What I would like to be able to do is set all the layer colors in the misc. architect xrefs in my "architect base" file and have those color settings propagate into my drawings as I create them. This comes into play especially if I have to create a new drawing late in the project, and I don't want to have to go set hundreds of layer colors individually. ?
Visretain comes to mind, but visretain (if I'm correct) is really for keeping xref color settings in your current file from session to session, not in a new file that you are creating using an xref.

The NCOPY command used to allow you to copy a nested object onto the current layer in the active drawing. Now, in 2012, it seems to copy the nested object, but it brings the reference layer with it. Is there a setting that can be changed so I can still do the former?

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.

Block Name is: " BlkName)));while);defun

BlockTableRecord.Position gets the position of the block in its owner. So if it is a nested block, it gets the position inside the parent block.
I want to get the position of a nested block in the space (model or paper). One way of doing this is getting the location of that parent, and if the parent is also nested, get that position and so on...and then calculate the position of the nested block.

Nesting phantom iAssemblies within another iAssembly? We are having a problem with the BOM not generating the correct multi-item parts lists. Even though the individual iAssemblies act correctly when viewing there individual BOMs, when these parts are nested inside another iAssembly and switched (Table Replace) between individual items, the BOM shows all dash numbers as the current active one.
Any unresolved issues within iAssemblies and the BOM?
