AutoCAD .NET :: XData To Polyline And Blocks
Apr 10, 2013
I am trying to store some data to polyline entities. and I'm planning to use xdata. Is it possible to store some string and integer values? Also each of them should have a tag name like block attiribute names.
For example:
Type= "XLPE"
Capacity= "Medium"
LengthMultiplier= 3
thickness=5
etc.
I searched internet for utilizing xdata, and it seems that Xdata is only for predefined types such as: datalayername, dataycoordinate, datazcoordinate,datascale etc. And it seems it is not possible to store more than one string with tag name.

I am trying to create a block that contains polylines. these polylines need to be able to have the width of them set individually.
What parameter do i need to assign so that this can happen?

Is there a routine that I could use to count the blocks that are in a closed polyline? The blocks may have or not one or more attributes.
In a previous session I saw a routine which was counting the blocks which had attributes in them, but it doesn't really work, because some of the blocks dont have attributes.
Also is there a routine that counts the different texts that are in the same polyline?

Any routine that will allow to draw a polyline through existing blocks, in the order the blocks should be numbered? Therefore when the sequence has been specified by the polyline then user to define the number system required, and the blocks are automatically numbered in the sequence of the polyine start to finish.

Why this code doesn't modify the xdata. I copied and modified another post.
it doesn't throw any errors. and objNewResBuf seems to have the right data.
Private Sub ChangeXData(ByVal objEntId As ObjectId,
ByVal strAppName As String)
Dim objDB As Database = objEntId.Database
Dim objTrans As Transaction = objDB.TransactionManager.StartTransaction
Dim objEnt As Entity = CType(objTrans.GetObject(objEntId, OpenMode.ForWrite,

i have a combo box which choose from 3 items one is blank. the triggered item changed event will erase the old set of corresponding xdata in the selected object and populate with new ones read from different text boxes. i was able to set the xdata for the first time ok. but when trying to dispose it won't dispose.

When capturing the Object Appended event of a block containing a "Drawing_No" attribute tag, then trying to add xdata to the object, I get a "Object reference not set to an instance of an object" error. I've tried writing the XData after committing the transaction but it didn't work.
If TypeOf e.DBObject Is BlockReference Then Dim bref As BlockReference = DirectCast(e.DBObject, BlockReference) If bref.AttributeCollection.Count <> 0 Then For Each attId As ObjectId In bref.AttributeCollection Dim attRef As AttributeReference = trans.GetObject(attId, OpenMode.ForRead) Select Case attRef.Tag Case "DRAWING_NO" WriteTitleBlock(e.DBObject.ObjectId) '<<Subroutine used to add XData Exit For End Select Next End If End If

How can know if entities are being manually copied and pasted between drawings.A thought is to add a GUID to each entities Xdata and check if the value is in the named object dictionary.

I have a lot of lines that I need a length, like in attached file. At this moment I do it with a vba that put fields in all lines.
The problems:
1) fields makes drawing slow to regen or after I modify line.
2) fields not follow lines slopes and position, if I stretch or move one end point of line. Text must be in middle of line.
So I thinking use reactors .
I tried reactor but I don't have much experience in lisp and I am having problems with persistent reactors, after I close file and open again, load lisp. Reactor not continue persistent.
This is a test that I tried. Works only for one line.
(defun print-align-text ( owner reactor lst / sp ep a d )
(setq sp (vlax-curve-getstartpoint line1))
(setq ep (vlax-curve-getendpoint line1))

I have read that is better store data using XData. In VBA I tried construct class module with events, without any success.

I'm trying to use a Selection Filter on Block Reference XData value. But I get no hits, it works fine with Lines and Polylines that has the same kind of XData.
Is it a bug or do I have to define my Selection Filter differently when working with Block Reference?
Here is a part of the code :
TypedValue[] flt = new TypedValue[]
{
new TypedValue(-4, " new TypedValue(-4, " new TypedValue(8, "POLYLINE_LAYER"),
new TypedValue(1001, "Object_Id"),
new TypedValue(1000, "166448"),
new TypedValue(-4, "AND>"),

I'm taking over some code from a developer that is no longer here. Right now when the code saved a resultbuffer object to xdata, I get an eregappidnotfound. Due to various forums, I believe this is because the ID is not being registered with the database before it's being inserted.
The error is thrown on this line: XData.ToXData(partCollection);
using (Autodesk.AutoCAD.DatabaseServices.DBObject dbObj = t.GetObject(objId, Autodesk.AutoCAD.DatabaseServices.OpenMode.ForWrite)){ DeviceName.SetDeviceName((Autodesk.AutoCAD.DatabaseServices.BlockReference)dbObj, txtDeviceName.Text);
dbObj.XData = XData.ToXData(partCollection); t.Commit();}
The code for the ToXData function is here:
public static ResultBuffer ToXData(PartCollection Parts) { //Write out some header information ResultBuffer rb = new ResultBuffer(new TypedValue(System.Convert.ToInt32(DxfCode.ExtendedDataRegAppName), XDATA_APP_NAME), new TypedValue(System.Convert.ToInt32(DxfCode.ExtendedDataInteger16), XDATA_TYPE), new [code].......

My code add xdata to any object properly except for a dynamic block with attribute. After code excutes it disappears from screen . Even undo make strange thing. I guess I screw the database somehow. But even audit doesn't show any fix applied.
Attach is a sample drawing. And below is my code.
<CommandMethod("pppp")> _ Shared Sub test1()
Dim Mydwg As Document = Application.DocumentManager.MdiActiveDocument
Dim Mydb As Database = Mydwg.Database Dim Myed As Editor = Mydwg.Editor
Dim MyRegisterApplication As String = "My_R_Cad"

with a function like this I added some xdata, some MULTILEADER
(defun c:add_xdata () (princ "Select: ") (setq ogg (car (entsel))) (addXdata ogg "TEST" "CODICE" "1256") (addXdata ogg "TEST" "MATERIALE" "LEGNO") (addXdata ogg "TEST" "TIPO" "A"))
Now with the following function can only select leaders who have linked the xdata application TEST
(setq selez_all (ssget "X" '((0 . "MULTILEADER")(-3 ("TEST")))))
I can not, however, find a way to select all MULTILEADER who have a particular value of XData.
For example I would select all MULTILEADER with MATERIALE = "LEGNO" and TIPO = "A".

I have LT 2012. I use Excel 2010 into my drawings to set up tables. When I opened the drawing I've been working on, I had lost all of yesterday's data. Command History shows dozens of these notations, "AcDbLine(41859) XData Handle Unknown, Null" In Help it says you can no longer turn handles off, so it should be ON. How can I point the drawing to my Excel data?

Due to modeling purposes, I need to convert a 3D polyline to a spline. What I have been doing is:
- change polyline fit/smooth to cubic from properties
- convert polyline to spline by typing spline -> object
- method -> fit from properties
You can see the original 3D polyline (green) and the resulting spline (magenta) in the attached drawing.When I zoom in and measure the distance between the two entities at different points along them, at some points the perpendicular distance exceeds 5 millimeters, and I want to ensure the deviation remains under 1 millimeter or even less.
I know I can change the knot parameterization of the spline, and this does work at some locations, but the difference increases at others.Why is there a 5.6 mm difference between the spline fit point and 3D polyline vertex, as measure in the attached drawing?
Now, I can go and manually stretch the fit point to coincide with the vertex. Also, I can add fit points between existing ones to drag the spline closer to the original 3D poly.
However, some of my polys are really long, and it is very time-consuming to do this manually while measuring points along the entities to make sure the distance stays small enough.
how to automate this process? For example a lisp that would maybe take the original vertex points, add say maybe 3 (not too many) new ones between them, and then generate a spline while making sure the deviation is less than the set value of 1mm? I am using AutoCAD 2013.

I've been working on a custom polyline object, and I've got it functioning!!Having said that, I plan to run its creation around picking a point for bounary selection.
(Other than trying to step through every vertecies) is there a technique I can thow the polyline data from a traceboundary result into my custom object? I've been trying to add the polyline from traceboundary to my object BEFORE it's added to the transaction by the way...I assume that's right, since I want to put it's data in my custom object then add my custom object to the transaction instead.

Is there any way at all to draw a new polyline - from the endpoint of another polyline, and have it automatically join as one polyline from the existing section??
I know this can be done via PEDIT, but its so laborious and soo many clicks, and I have alot of segmented Polylines that I need to consolidate when I draft.

I need a Reactor to Modify Xdata - Length - contained in Line Object if this Line is modified (stretched, breaked, trimmed, etc).The routine need to verify if Line contain Xdata and modify it (and works with multiple selection).
I tried for long hours, but without success. I tried to create a list of entities while the reactor is applied, but doing so need another reactor to change these entities after the first Reactor works.The codes I used are below:
{code}
;If it just 1 string only you want to add
(defun add_xdata_str (e a v);;;EName APPID String_value
(and (not (tblsearch "APPID" a))
(regapp a))
(and (= (type e) 'ENAME)

Any way I can align a new polyline to a reference polyline (orig polyline).
The 2 polys will be generally the same length, however, the number of vertices will differ.
Also I need to mantain the same distance between the vertices on the new poly and the new and reference poly won't follow the same direction.

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.
