AutoCAD .NET :: Get New ID Entity?
Dec 27, 2013
I am doing a routine to break a polyline in different points.
I do this by prompt with SendCommand.
string strHandle1 = id.Handle.ToString(); string strEntName1 = "(handent "" + strHandle1 + "")"; string strCommand = "_BREAK" + "
" + strEntName1 + "
" + String_point + "
" + String_point + "
"; Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.SendStringToExecute(strCommand, true, false, true);
However, I need the new Id of polyline to continue break in other point.
I have tried this:
ObjectId idNewEntity = Autodesk.AutoCAD.Internal.Utils.EntLast();
to get the last entity created, but with "break" doesn´t consider new entity created. Then, How can I get the new Id after "break"?

I would like to add additional entities to the selection if any of the selected entities contains a an xdata value.
If I put the condition into the ImpliedSelectionChanged reactor I imagine will probably loop back on itself.

I need to export points from 3D map as a .shp file so I can bring them into Maya and have them line up exactly where they need to be based on their coordinates. The points line up pretty close to right in map 3d, and they have a style assigned to them. When I go to the Map --> Tools --> Export, I choose .shp as the file output, and go through and select the layer I need to export. When I've got everything set up, I get an error message saying "no entity to export." I have searched on the internet for this error but not a lot comes up. I'm not sure what I'm missing in order to make the points export.

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'm trying to add an attribute to an entity, however it seems that the AttributeDefinition requires a Point3d and as such appear in my modelspace. I don't want this, i just wanted it to appear as an attribute with a value when i click on my entity, is there any way of making it so that i does not add into modelspace?
BlockTable bt = (BlockTable)trans.GetObject(db.BlockTableId, OpenMode.ForRead);for (int i = 0; i < prSelectionResult.Value.Count; i++){ // Get the entity the user had selectedEntity ent = (Entity)trans.GetObject(prSelectionResult.Value[i].ObjectId, OpenMode.ForWrite);if (ent.GetType() == typeof(BlockReference)) { // Add attribute to layerBlockReference blockRef = (BlockReference)ent;.

I have a method DrawMLeaderLine(Database db, Transaction tr, Point3d point, string text) that draws me a MLeader line to the given point with the given text as annotation. The MLeader line points to the midpoint of a Line entity. What I need is a binding between the Line midpoint and the MLeader line, so when I move or resize the Line, the MLeader line should follow! I already tried to solve that, using constraints, but it doesn't work for Leaders.
This is my code...
public static MLeader DrawMLeaderLine(Database db, Transaction tr, Point3d point, string text) { Point3d mTextLocation = point + new Vector3d(5, 5, 0); BlockTableRecord btr = tr.GetObject(db.CurrentSpaceId, OpenMode.ForWrite) as BlockTableRecord; MText mText = new MText(); mText.SetDatabaseDefaults(); mText.SetContentsRtf(text); [code]........
will be called from a different class...
Line line = DrawingUtil.DrawLine(doc.Database, tr, closestPoints.Item1, closestPoints.Item2); //Get midpoint of line double midPointX = (line.EndPoint.X + line.StartPoint.X) / 2.0d; double midPointY = (line.EndPoint.Y + line.StartPoint.Y) / 2.0d; Point3d midPointOfLine = new Point3d(midPointX, midPointY, 0); //Draw the leaderline MLeader leaderLine = DrawingUtil.DrawMLeaderLine(doc.Database, tr, midPointOfLine, "Connection");

I commonly send serialized data to .net functions.
One of the items I send in the entity name of something as a string.
Once my .net function is done, it constructs a resultbuffer to send back to lisp.
I had been doing this:
AcDb.ObjectId id = new ObjectId(Convert.ToInt32(ename));
but the Convert function is throwing an exception.
I do not recall this happening before, but forget if I ever tested it.
I am on win 7 64 bit.

For some strange reason i'm suddenly unable to select more than one entity just by clicking with my mouse.
for eg if i select a line and try to select a second one ,the first automatically is deselected.
i'm only able to select multiple entities using the" cross windowing" or 'fulyl windowing' an entity.
this is only a recent occurence and i suspect i may have inadvertently pressed some key.

Can you add an attribute to a non-blocked entity? Basically, I want to "name" plines.
In case I'm going about this wrong, let me ask the question another way. I'm just getting used to the wonders of attributes & data extraction (I love it!). Right now I have blocks with attributes that I use data extraction to count. I also need some way to calculate length. These blocks represent electrical devices - then I need to calculate the amount of wire used to connect the devices.
So now I use a pline to join the devices, get the length of that polyline, and then manually enter that length into the spreadsheet from the data extraction. But...I'm thinking if I can link an attribute to a pline, then I can include that in the data extraction and automate it. But I don't see how I can use a block for this, since the pline will be completely variable and needs to be "custom-fit" for each circuit.

I have a client that just started using C3D 2010. When I sent him a topographic survey with contour lines (I am also using C3D 2010) he called me and asked if there was a way to select an individual contour line and have it display the elevation in the 'properties' dialog box. I have not been able to find an answer for him.

Is there a way to access the object of the last entity modified.
If a dynamic block is changed I want to collect the changes.
I'm guessing I use the AcadDocument_EndCommand to kick off the routine but don't know how to identify the modified object.

I'm borrowing from the samples library in the Inventor:
Public Sub GetSingleSelection()
' Get a feature selection from the user
Dim oObject As Object
Set oObject = ThisApplication.CommandManager.Pick(kPartFeatureFilter, "Pick a feature")
MsgBox "Picked: " & oObject.Name
End Sub
Works fine, and is fairly simple, but the problem I'm having is if I press the escape key after starting the command, but before making my selection, I'm not able to start the command again.
I realize from my searching that using the Selection (Simple) sample allows for an interrupt, with some modification, was just wondering if there was something similar for this simpler selection option.

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.

How could I prompt a "two points" line entity from the user?
Something similar to " Editor.GetPoint() " ??
I was trying to use Editor.GetPoint() method two times. But this option does not show the preview of a line.
I also tried a combination of
doc.SendStringToExecute("line ");
db.ObjectAppended += new ObjectEventHandler(LineAppended);
but this option triggers LineAppended event handler as soon as I create the first point of a line. So it does not work.

I am using ACADE 2008 and VB.NET. I have a multitude of drawings that I am doing the same three and four operations on and would like to write VB.NET program to do it. I can get my selections set just fine, but my first problem is figuring out how to change all drawing entities color and linetype to "ByLayer". So far I have not gotten past changing just the color value. I have tried multiple variations on the following line without success:
myAcadEnt.Color = Colors.Color.FromDictionaryName("ByLayer")

Our office has upgraded to new Windows 7 computers with AutoCAD 2013.
For the last (3) years, we have had an RTEXT in our titleblock file that shows the path, file name, date, and time. This RTEXT thingy was originally copied from a consultants file to ours. The titleblock file is x-reffed to the other sheet files, and has been working fine in all files until the upgrade.
Now, when we open a file, the only thing that is shown for the RTEXT is the bounding box. This happens on all of our computers. The express tools are installed. If I type RTEXT > [enter], it displays correctly and will work fine ... until the CAD is shut down. If it is re-opened, once again, just the bounding box.
Typing the command every time I open the file is a nuisance for me, and is something that others in the office would never get used to doing.

I am new to Inventor API, but have some experiences in SolidWorks API.
How can I select an entity at a given spacial point (x, y, z)? For example, I want to select a face or edge that is on a given (x, y, z) point. I can not find such an API, except for interactive selections.

Is it possible to constrain a dimension to an entity?
Outside the block editor you can display a constrained dimension with a dimension style but it doesn't appear as you can do the same inside blocks.
I want show the dimension of a line in a block that is constrained by a dimensional constraint but I can't figure out how to constrain the dimension extents to anything.
I could put in an attribute but it doesn't look like you can constrain attributes either. And then I would need to work out how to pass the value into it.
