Also to place rebar systems individually on each.įor early scheme designs, walls can be modeled full height then split at a later moment, although this is not recommended as you will lose associated filters. Modelling ConcreteĬoncrete columns should be modeled floor (bottom face) to floor (top face), enabling them to be scheduled individually according to the construction logic and for quantification purposes. Use pick line tool is dangerous in any case at this step, as CAD lines can lead us to eccentric elements, or elements of a geometry more complex than intended. Only if there is no clear reference or dimension with respect to an element, this should be located considering the direct measuring from a CAD file or selecting elements from imported files.Afterwards, the floor boundaries should be delimited taking as a reference the elements mentioned in the previous points, as long as there are no explicit references with properly defined dimensions/offsets.The logic connection among elements of different levels is to be respected, provided that the relation keeps some common sense.Subsequently, beams, structural walls and floor openings should be placed in relation to columns (aligned to face, to axis, with a particular offset…) of the corresponding level, respecting the load paths.The next step consists of the placement of columns aligned with the structural axis’ intersections in case of eccentricity columns should be respectively related to axes through appropriate dimensions.The main arrangement of the structure and facade should then be established, taking into consideration first the symmetries and then those annotations that are clearly expressed.The modeling process should begin with the study of the symmetries and general geometrical relationships among the different parts of the building.This information should therefore be adequately reinterpreted and filtered so as to avoid any source of further irreversible inaccuracies when developing a BIM model. The information that is available in order to model a building, particularly the structure, very often contains errors and lack of precision due to an inconsistent AutoCAD or similar work. Modelling in Structure Projects Modelling hierarchy Massing, 2d lines and a structural narrative.Ĭreate 2D construction documents, general estimating and 3D spatial validationĭetailed estimating, and 3D Spatial Validation LOD requirements will be specified prior to start modelling, and should be in accordance to the intended uses and project phase. That means that it should be clear which level of development (LOD) the elements in a model should reach. It will greatly improve the performance of the model:ĭo not overmodel. Please make sure to modify the User Interface setting in ALL user local computers who are working on this project:Ĭheck out the “Enable analytical model” for structural elements if you are not going to use it. To disable this feature, go to File→ Options→ User Interface, and uncheck “Structural analysis and tools”. Procedure Project configuration Analytical model generic settingsĭisable the automatic Analytical Support Check feature if you are not going to use it, it may significantly decrease the performance of the model. This document explains key tips to achieve so. Structural modelling in Revit can be very useful, but it’s key to manage our model properly, in order to keep it clean and organized, and the file fluent and weight optimized.
