Modelling in Structure Projects Modelling hierarchy 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. 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 modeling process should begin with the study of the symmetries and general geometrical relationships among the different parts of the building. 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. Subsequently, beams, structural walls and floor openings should be placed in relation Where can I purchase Revit Structure 2016?
columns aligned to face, to axis, with a particular offset… of the corresponding level, respecting the load paths. The logic connection among elements of different levels is to be respected, provided that the relation keeps some common sense. 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.
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. Modelling Concrete Concrete columns should be modeled floor bottom face to floor top faceenabling them to be scheduled individually according to the construction logic and for quantification purposes.
Also to place rebar systems individually on each. For early scheme designs, walls can be modeled full height then split at a later moment, although this is not recommended as you will Where can I purchase Revit Structure 2016?
associated filters. You cannot tag slab edges neither they have analytical properties therefore it's best to use a beam for slab edge thickenings that need to be scheduled. When modifying a floor you will often get the message - "Would you like walls that go up to this floor's level to attach to its bottom? Openings through Walls, should be modeled using structural doors and window families, as this workflow allows quicker placement, editing Where can I purchase Revit Structure 2016? sizes through duplication of families and all information can be viewed in schedules which can also be used to quickly edit.
Beams should be modeled column to column. This means from axis to axis, not from face to face. Where can I purchase Revit Structure 2016?
is important to model the way that is going to be built. Use reference planes to place structural members like beams in sloped workplanes. Name allways the reference planes that are important reference in model. Be aware that reference planes could have to be included in groups when structural members are hosted on them. Modelling Steel If possible, avoid excessive modeling of the 3D connections, such as connection plates and bolts, in Revit Structure.
When doing typical detail, create or use 2D detail component connections instead. All steelwork views to be set to Detail Level: Otherwise we will be seeing schematic axis lines for steel members. That is the default behaviour of steel families in coarse level of detail although it could be modified. Make sure you select the appropriate structural usage from the element properties. This will affect visibility of objects. Steel columns should be modeled floor top face to floor top faceenabling them to be scheduled individually according to the construction logic and for quantification purposes.
Every steel member should be modelled considering the axis line and its insertion in relation to other steel member axis lines. Actual Where can I purchase Revit Structure 2016? will be cut accordingly. Remember that structural truss families are the layout of the truss rules of creationbut the individual members will act as what they are, this is, instances of beam families structural framing category.
Cutting elements Cutting structural elements does not respond always to the same logic as cutting generic elements. There are several options for cutting structural members: And you will need two structural intersecting elements to use it. That is very useful, and will work for every beam and column except for those with Concrete Material Behavior Family Parameter.
You can even attach Structural Columns to a Reference Plane, just as you would attach them to a floor or a roof. Opening by Face Other standard tool: With this tool you can customize the openings on your structural elements beams and columns but with some restrictions: Not void masses but solid masses, and cut the beam or column with that element.
Masses can be used as auxiliary elements, better than in-place components, because normally they are already a hidden category, non visible in views. Additionally, they won't appear as in-place components in category schedules in-place components wouldbecause they have their own category. The only downside is that they do not cut steel elements. Structural elements information When we load a structural element like columns or framing elements, the default families do not contain the structural material, which is very important for schedules in order to get the linear weight of steel elements.
Weight W and area A are set by default, and do not rely on the structural material or shape. Therefore it is a good practice to add to these families the real area coming from the shape and a linear weight parameter, which depends on the material density and can be customized if necessary: Use shared parameters to create the properties in structural families which are necessary to schedule or tag See Parameters guideline.
Otherwise the information will remain in the family and it will not have any impact on the global model information. Default families do not use shared parameters for dimensional information, which is specially relevant in concrete structural elements. Rebars Utilize rebar sets instead of individual rebar elements where possible: You must take into account that bars have a special visibility, which can be accessed by selecting the own bar and settings in the Properties window, Graphics.
In that window you choose for each view 2 possibilities: View unobscured. To see the bars through the element that contains them. View as solid. To see not as lines but as solid bars. The rebar cover is controlled by parameters of instance, containing all the elements that can contain them by default. Those categories of elements that can be structural or not, e.
Model rebar only when strictly necessary. Use detail elements instead unless a rebar digital model is needed for some purpose. Rebar elements overload models. If they are stored in a file apart this file can act as a repository, and then import the details to other project files. Drafting views should be sorted by the type of detail, and there should be a view naming system. Notice that the only views that can be transferred from file to file are: Schedules Drafting views Sheets with only 2D elements.
If they have already model viewports they cannot be transferred. Use parametric detail elements components to describe concrete elements rebar. In modern versions of Revit they can be scheduled and are very useful for rebar quantifying. Previous statement does not apply when working with steel elements, which are displayed usually as lines. The analytical model can be displayed in all views. In the normal views it tends to be disabled by default. Special views should be created only for the analytical model.
It can be useful to have a view Where can I purchase Revit Structure 2016? see the analytical model with the physical model with transparency. The visibility of analytical elements works the same as the visibility of any element of the physical model: If we apply a concrete surface shading, we should make sure to print Where can I purchase Revit Structure 2016?
drawings using raster processing, as all annotation elements and transparent fill boundaries appear above the surface shade. Use filters in your views for the above shading of elements, rather than the overall concrete Where can I purchase Revit Structure 2016? shade, which won't shade the ends of slabs, concrete stairs, and tops and sides of walls. Applying surface shading with filters overcomes this problem. View visibility settings by structural discipline Non structural Walls and Floors will be hidden.
But not the elements like windows or doors hosted in them. Show hidden lines option can be overriden in any discipline from version and subsequents. Analytical Model Analytical model will be created simultaneously with the physical model without a conscious effort. By default, for the structural members the attached analytical element will be located at: Therefore some touch-ups should be done before exporting, especially in connection brackets with beams and slabs, as well as the walls and the slabs of support.
In order to do so, we should click on the Analyze tab, Analytical Model Tools panel, Analytical Adjust to manually adjust the analytical model. From here you can also delete openings that should not be viewed in the analysis. This does not change the physical model. To "reset" the modifications made: The element will return to their form or original scenario according to the physical model.
Before exporting the model you should check it: A series of warnings indicating possible errors or inconsistencies in the model will appear. The checks can be activated manually or by default: Better enable them by default when the model is practically finished. Analytical lines need to be reset to floor level if Where can I purchase Revit Structure 2016?
are attached to floors. For sloped floors the analytical slab will only be sloped as well if the slope was set using a slope arrow. Floors with modified sub-elements will have an horizontal attached analytical slab.
CSiXRevit supports the following Exchange workflows: The toolkit contains the following items: Accessing to the Autodesk services, and by extending the Revit model to Autodesk Robot Structural Analysis Professional software, or supported third party analysis solutions. Once complete, analysis results can be easily stored and explored in the Where can I purchase Revit Structure 2016?
environment. Where can I purchase Revit Structure 2016? hierarchy:
Special views should be created only for the analytical model. Use parametric detail elements components the way that is going. Notice that the only views that can be transferred from file to file are: Name allways the Where can I purchase Revit Structure 2016? planes that are important reference in model. It is important to model of steel families in coarse all the elements that can contain them by default. The rebar cover is controlled by parameters of instance, containing level of detail although it. But she goes back, reports later by using the browser.
