Block mit Mausklick auswählen statt Namen eingeben

Question

Dies ist mein Code, der einen bestimmten Block in meiner DWG-Datei nach dem eingegebenen Namen auswählt. Aber ich möchte ganze Seite auswählen und nur Tabelle eines bestimmten Blocks. Und auch die Überschrift Teil gibt mir auch falsche Informationen Ich habe ein Attribut vier, aber es druckt nur eine auf der Überschrift Teil.Bitte schlagen Sie die Lösung vor.

namespace TableCreation 
    { 
    public class Commands 
    { 
    // Set up some formatting constants 
    // for the table 

    private const double colWidth = 15.0; 
    private const double rowHeight = 3.0; 
    private const double textHeight = 1.0; 

    private const CellAlignment cellAlign = 
     CellAlignment.MiddleCenter; 

    // Helper function to set text height 
    // and alignment of specific cells, 
    // as well as inserting the text 

    static public void SetCellText(Table tb, int row, int col, string value) 
    { 
     tb.SetAlignment(row, col, cellAlign); 
     tb.SetTextHeight(row, col, textHeight); 
     tb.SetTextString(row, col, value); 
    }

Answer 1

den Benutzer zu bitten, einen Block auf dem Bildschirm auszuwählen, die Sie PromptEntityOptions stattdessen wählen Sie einen BlockReference verwenden können. Ich änderte dieser Teil des Codes gehören:

[CommandMethod("BAT")] 
static public void BlockAttributeTable() 
{ 
    Document doc = Application.DocumentManager.MdiActiveDocument; 
    Database db = doc.Database; 
    Editor ed = doc.Editor; 

    PromptEntityOptions opts = new PromptEntityOptions("\nSelect a block: "); 
    opts.SetRejectMessage("Only block references"); 
    opts.AddAllowedClass(typeof(BlockReference), true); 
    PromptEntityResult pr = ed.GetEntity(opts); 

    if (pr.Status == PromptStatus.OK) 
    { 
    Transaction tr = doc.TransactionManager.StartTransaction(); 
    using (tr) 
    { 
     BlockReference blockRef = tr.GetObject(pr.ObjectId, OpenMode.ForRead) as BlockReference; 

     BlockTableRecord bd = (BlockTableRecord)tr.GetObject(blockRef.BlockTableRecord, OpenMode.ForRead); 
     foreach (ObjectId adId in bd) 
     { 
     // ToDo: here you can handle entities inside the block definition 
     } 

    } 
    } 
}
