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 for your answer. My aim is to create a data stracture that holds all this info, for calculations and so. In the far end, I want it to be an auto script that bild that proccesed text file.
For start, how do I read the atributs of an entity? How do I choose a layer, and read every object from it?
Thanks, EATTEXT will help me for now, and I do wait for your help to continue.
You can quite get the objectIDs of all text on a layer passing a SelectionFilter to the Editor.selectAll method::
TypedValue[] tv = new TypedValue[] {new TypedValue((int)DxfCode.Start, "TEXT"), new TypedValue((int)DxfCode.LayerName, "Layer 1")};
SelectionFilter sf = new SelectionFilter(tv);
SelectionSet set = ed.SelectAll(sf).Value;
You can then open the text entities from the objectIDs in the selectionSet and then access their properties.
You could either get the user to type in a layer name using Editor.GetString() or you could put a combobox on a form and get the user to pick one or smething like that.
You can get all layer names by iterating through all the LayerTableRecords in the LayerTable:
List<string> names = new List<string>();
LayerTable lt = (LayerTable)trans.GetObject(db.LayerTableId, OpenMode.ForRead);
foreach(ObjectId id in lt)
{
LayerTableRecord ltr = (LayerTableRecord)trans.GetObject(id, OpenMode.ForRead);
names.Add(ltr.Name);
}

Sorry for the begginer question, beside "Hello World" its my first program in this enviroment. Do I write it in a CommandMethod? What do I do with the objectIDs?
