CXBLKCOUNTBlöcke und AttributeVersion 1.0.0In AutoCAD getestet

Blöcke nach Namen zählen

Listet auf, wie oft jeder Block in der Zeichnung oder der Auswahl vorkommt, den häufigsten zuerst. Die Liste lässt sich als Text in die Zeichnung setzen.

So verwenden Sie ihn

  1. CXBLKCOUNT eingeben und All oder Selection wählen.
  2. Die Liste in der Befehlszeile lesen.
  3. Mit Yes wird sie in der Zeichnung platziert.

Gut zu wissen

  • Gezählt werden die Blöcke im aktuellen Modell- oder Layoutregister.

In AutoCAD laden

  1. Speichern Sie die Datei an einem beliebigen Ort.
  2. Geben Sie APPLOAD ein, wählen Sie die Datei und klicken Sie auf Laden.
  3. Geben Sie den Befehl ein: CXBLKCOUNT.

Damit er bei jedem Start bereitsteht, fügen Sie ihn im selben Dialog zum Startup-Set hinzu, oder laden Sie mit dem optionalen Loader einen ganzen Ordner auf einmal. Der optionale Loader

In AutoCAD (Vollversion) getestet. Andere Programme, die AutoLISP ausführen, funktionieren vielleicht, wurden aber nicht getestet.

Der Code

Reiner Text, nichts ist versteckt. Kopieren Sie ihn in eine Datei namens cxblkcount.lsp oder laden Sie ihn herunter.
