hi,
i want to write a command in C# that alow user to do 2 things:
1. choose a layer to work on
2. make a list/table of all objects in that layer, and their X Y coordinates.
for example - if a DWG file contain few layers, one of them has names (and only names). there are ~1500 objacts (text type) in that layer. every objact have a string (100,101,...,1350,1351...) and locating (X and Y). I want to be able to pick this layer, then bild a text file like this: (name X Y)
100 20456 40789
101 20344 40348
102 21034 40456
.
.
.
its dont has to be sorted. how do I do it? can you give me the solution or any lift to proggress?
thanks :)
schaap.

A way to this is:
- make a selection set (Editor.SelectAll() method) with a SelectionFilter (http://www.acadnetwork.com/topic-85.msg184.html#new) to get all DBText objects on the specified layer.
- instanciate a System.IO.StreamWriter with the file you want to create.
- within a Transaction, open every seleted object and write a line (WriteLine() method) in the file with the text TextString and the text Position.X and Position.Y.
Post what you've written yet so that it'll be easier to help you.

hi, thanks for helping.
I'm a newbi, Dont really know where to start with your link.
I found the EATTEXT command witch gives me what I need, but in a manual way (export to excel, then sorting and filtering...). I want to write a script that does it, so I'll have a data structure thats holds all that data' for more calculations and proccesing.
were do I start?

Try this code
[CommandMethod("txtdata", CommandFlags.Modal | CommandFlags.UsePickSet)]
public void TextDataExtraction()
{
StringBuilder sb = new StringBuilder();
List<string[]> data = new List<string[]>();
// get active drawing
Document doc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;
// get document editor
Editor ed = doc.Editor;
// build selection filter , put layers you need, separated by commas
//SelectionFilter sfilter= new SelectionFilter(new TypedValue[]{new TypedValue(0,"text"),new TypedValue(8,"Layer1,Layer2,Layer999")});
// to select all text on all alyers you have to elimminate second typedvalue from filter:
SelectionFilter sfilter = new SelectionFilter(new TypedValue[] { new TypedValue(0, "text") });
// request for objects to be selected in the whole drawing
PromptSelectionResult res = ed.SelectAll(sfilter);
try
{
//check on valid selection result
if (res.Status == PromptStatus.OK)
{
//get object transaction
using (Transaction tr = doc.TransactionManager.StartTransaction())
{
foreach (ObjectId id in res.Value.GetObjectIds())
{
Entity ent = tr.GetObject(id, OpenMode.ForRead, false) as Entity;
DBText txt = ent as DBText;
if (txt != null)
{
//if text has an empty string it will be replaced with "---"
string record = string.Format("{0}\t{1:f2}\t{2:f2}\n", txt.TextString == "" ? "---" : txt.TextString, txt.Position.X, txt.Position.Y);
//add record to string builder
sb.Append(record);
string[] item = new string[3];
item[0] = txt.TextString == "" ? "---" : txt.TextString;//<--- if text has an empty string it will be replaced with "---"
item[1] = string.Format("{0:f3}", txt.Position.X);//<--- precision 3 decimals
item[2] = string.Format("{0:f3}", txt.Position.Y);//<--- precision 3 decimals
data.Add(item);
}
}
//write data to CSV file
using (StreamWriter sw = new StreamWriter(@"C:\Test\TextRecords.csv")) //<---change file name here
{
foreach ( string[] record in data)
{
// create tab delimited string
string line = string.Format("{0}\t{1:f2}\t{2:f2}", record[0], record[1], record[2]);
sw.WriteLine(line);
}
sw.Close();
}
tr.Commit();
}
}
}
catch (Autodesk.AutoCAD.Runtime.Exception ex)
{
ed.WriteMessage("\n" + ex.Message + "\n" + ex.Source + "\n" + ex.StackTrace);
}
}
