Revision as of 18:36, 13 June 2024 by FuzzyBot (talk | contribs) (Updating to match new version of source page)
In v1.0 the BIM, Native-IFC and Arch Workbenches have been merged into the integrated BIM Workbench.
This page has been updated for that version.

Introduction

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.

Voir le guide de migration BIM de FreeCAD pour un aperçu rapide si vous êtes déjà utilisateur d'une autre application BIM.

Les développeurs de Draft, Arch et BIM collaborent également avec la communauté OSArch dans le but ultime d'améliorer la conception des bâtiments en utilisant un logiciel entièrement gratuit.

Commencer

Lorsque vous démarrez l'atelier BIM pour la première fois, une boîte de dialogue de bienvenue s'affiche, donnant un aperçu rapide du fonctionnement de l'atelier et permettant à l'utilisateur de démarrer un tutoriel ludique. Le dialogue de bienvenue est également disponible dans le menu aide. Lorsque vous fermez l'écran de bienvenue en cliquant sur OK, la Boîte de dialogue configuration BIM s'affiche. Elle permet à l'utilisateur de définir rapidement certaines des préférences les plus courantes liées à BIM de FreeCAD sans qu'il soit nécessaire de parcourir les pages complètes des paramètres de préférences FreeCAD.

L'outil Configuration du projet BIM vous permet de configurer rapidement un projet BIM en renseignant certaines informations de base sur votre projet. Vous pouvez ensuite, par exemple, utiliser les différents outils de dessin 2D pour dessiner des repères et des lignes de base, Puis utiliser les différents outils de modélisation 3D pour créer automatiquement des objets BIM 3D à partir d'eux. Une ligne, par exemple, peut devenir un mur simplement en la sélectionnant et en appuyant sur le bouton Mur.

Si vous êtes habitué à une autre application BIM, consultez notre Tableau de compatibilité des applications BIM pour connaître vos marques lors du démarrage avec FreeCAD.

Le BIM Tutoriel est un moyen facile de se mettre rapidement sur la bonne voie avec l'atelier BIM.

Outils

The BIM workbench gathers tools from several other FreeCAD workbenches, mainly Draft and Part, roughly reorganized in logical categories.

De plus, si de telles extensions sont installées, des outils de Reinforcement (armatures supplémentaires), Fasteners (boulons et vis), Flamingo/Dodo (outils de structure métallique et de tuyauterie) et Parts Library sont automatiquement inclus dans l'atelier BIM.

L'atelier BIM ajoute également une série d'éléments dans la barre d'état de FreeCAD et quelques éléments de menu contextuel, accessibles en cliquant avec le bouton droit de la souris dans la vue 3D ou dans l'arborescence.

Dessin 2D

Les objets 2D sont couramment utilisés comme aide à la conception ou pour tracer des lignes de base et des profils sur lesquels construire des objets BIM. Ils peuvent également être utilisés pour dessiner des symboles et des annotations dans votre modèle. En plus des esquisses, qui utilisent leur propre système de coordonnées, des objets 2D seront dessinés sur le plan de travail sélectionné.

  • Sketch: Creates‎ a new sketch and enters sketch edit mode. Sketches are advanced 2D objects with constraints support.
  • Line: Creates a straight line.
  • Polyline: Creates a polyline (also called wire), a sequence of several connected line segments.
  • Circle: Creates a circle from a center and a radius.
  • Arc: Creates a circular arc from a center, a radius, a start angle and an aperture angle.
  • Arc by 3 points: Creates a circular arc from three points that define its circumference.
  • Fillet: Creates a fillet, a rounded corner, or a chamfer, a straight edge, between two Draft Lines.
  • Ellipse: Creates an ellipse from two points defining a rectangle in which the ellipse will fit.
  • Polygon: Creates a regular polygon from a center and a radius.
  • Rectangle: Creates a rectangle from two points.
  • B-spline: Creates a B-spline curve from several points.
  • Point: Creates a simple point.

Annotation

Les annotations sont des objets d'aide visuels pouvant être placés dans votre modèle. Ils peuvent être utilisés pour exporter votre modèle directement vers un format 2D tel que DXF, ou être réutilisés lors de la création de vues 2D de votre modèle avec l'atelier TechDraw.
