Arbeitsbereich BIM
Diese Seite wurde für diese Version aktualisiert.
Einleitung
The BIM Workbench provides a modern Building Information Modelling workflow in FreeCAD, with fully parametric objects such as walls, beams, roofs, windows, stairs, pipes, and furniture. It supports Industry Foundation Classes (IFC) files, and the production of 2D plans in combination with the TechDraw Workbench.
The BIM Workbench imports tools from the Draft Workbench, as it uses its 2D objects to build 3D parametric objects. But it can also use solid shapes created with other workbenches like Part and PartDesign.
Siehe FreeCAD BIM Umstiegsleitfaden für einen schnellen Überblick, wenn Sie bereits Benutzer einer anderen BIM-Anwendung sind.
Die Entwickler von Draft und BIM arbeiten auch mit der größeren OSArch-Gemeinschaft zusammen, mit dem ultimativen Ziel, den Entwurf von Gebäuden durch den Einsatz völlig freier Software zu verbessern.
Erste Schritte
Beim ersten Start des BIM Arbeitsbereichs wird ein Begrüßungsdialog angezeigt, der einen schnellen Überblick über die Funktionsweise des Arbeitsbereichs gibt und es dem Benutzer ermöglicht, ein BIM im Spiel Tutorium zu starten. Der Begrüßungsdialog ist auch über das Menü Hilfe verfügbar. Wenn der Begrüßungsbildschirm durch Klicken auf OK geschlossen wird, wird der BIM Setup Dialog angezeigt, der es dem Benutzer ermöglicht, schnell einige der häufigsten BIM-bezogenen Einstellungen von FreeCAD vorzunehmen, ohne durch die vollständigen FreeCAD Einstellungsseiten blättern zu müssen.
Das BIM Projekt Einrichtung Werkzeug ermöglicht es dir, ein BIM Projekt schnell einzurichten, indem du einige grundlegende Informationen über dein Projekt ausfüllst. Du kannst dann z. B. die verschiedenen 2D Zeichenwerkzeuge verwenden, um Richtlinien und Grundlinien zu skizzieren, und dann die verschiedenen 3D Modellierungswerkzeuge verwenden, um daraus automatisch 3D BIM Objekte zu erstellen. Eine Linie kann z. B. zu einer Wand werden, indem du sie einfach auswählst und die Wand Schaltfläche drückst.
Wenn du an eine andere BIM Anwendung gewöhnt bist, prüfe unserere BIM Anwendungskompatibilitätstabelle um beim Start mit FreeCAD deine Schulnoten zu erhalten.
Das in-game tutorial ist ein einfacher Weg, um schnell mit dem BIM Arbeitsbereich zurechtzukommen.
Werkzeuge
The BIM workbench gathers tools from several other FreeCAD workbenches, mainly Draft and Part, roughly reorganized in logical categories.
Außerdem sind, falls solche Addons installiert wurden, Werkzeuge von Reinforcement (zusätzliche Werkzeuge für Bewehrungsstäbe), Fasteners (Verbindungselemente wie Bolzen, Schrauben usw.), Flamingo/Dodo (Metallstruktur- und Rohrleitungswerkzeuge) und Parts-Library (Teilebibliothek) automatisch im BIM-Arbeitsbereich enthalten.
Der BIM Arbeitsbereich fügt auch eine Reihe von Elementen in der Statusleiste von FreeCAD und einige Kontextmenüelemente hinzu, die durch einen Rechtsklick in der 3D Ansicht oder in der Baumansicht zugänglich sind.
2D Entwurf
2D Objekte werden häufig als Zeichenhilfe oder zum Zeichnen von Grundlinien und Profilen verwendet, auf denen BIM Objekte aufgebaut werden. Sie können auch zum Zeichnen von Symbolen und Anmerkungen in deinem Modell verwendet werden. Abgesehen von Skizzen, die ein eigenes Koordinatensystem verwenden, werden 2D Objekte auf der aktuellen Arbeitsebene gezeichnet.

Anmerkung
Anmerkungen sind visuelle Hilfsobjekte, die in deinem Modell platziert werden können. Sie können verwendet werden, um dein Modell direkt in ein 2D Format wie DXF zu exportieren, oder bei der Erstellung von 2D Ansichten deines Modells mit der TechDraw Arbeitsbereich wiederverwendet werden.
