ams. This communication is based on the IFC format (acronym for INDUSTRY FOUNDATION CLASSES). IFC is an open data exchange format in the architecture, engineering and construction sector. It is free to access (as it does not depend upon any particular developer), and it allows for the exchange of model information between applications from different developers. It is not possible to develop efficient BIM models without taking into account the intended BIM USES from the start. In this case, by not including the requirements of the IFC format and of the CYPE tools as another BIM Use upon starting a new project with REVIT, it will lead to the appearance of interoperability problems that can end up halting the workflow. This is because there are two types of possible interaction with an IFC– viewing the information that it contains (e.g. with an IFC viewer) and working with this information (e.g. with CYPE’s calculation solutions). Whilst the first case is relatively easy to achieve, t

he second interaction is very sensitive due to differences in the internal information structures of each software program. The IFC format is capable of transferring data from one application to another, but this does not mean that this data follows the fundamental internal norms of the software which it is transferred to. For example, general purpose software like Revit or Archicad, allow the user to model elements in various ways. Such flexibility is possible because they do not have to respond to complex specific calculations for detailed code justifications. On the other hand, in CYPE’s solutions there is usually only one way of modelling elements – the one which offers greater guarantees in the calculation processes of that tool. It is important to take these restrictions into account when choosing the way in which to model in the general purpose software if there is to be good communication.

ructure At CYPE we work so that the technician does not need to know in detail the internal structure of the IFC, automatically facilitating its “correct” generation from the modelling tools available in each program. Nevertheless, for a greater understanding of this guide some basic concepts surrounding this term will be clarified. IFC is a format developed by the buildingSMART initiative, for projects where there is collaboration between users of BIM applications made by different providers. This implies working in an Open BIM workflow as it does not depend on formats belonging to specific developers. The most up-to-date version is IFC 4 (major release), which complies with ISO 16739:2013. Just like with all ´BIM´ formats, the IFC format contains geometric entities with associated information in the form of parameters. These entities are grouped into CLASSES and TYPES. CLASSES are a general grouping of elements according to what they are (walls, floors, roofs etc.), associating

attributes and dependencies to them. TYPES are a more specific grouping within classes, that distinguish between their individual specific components (for example, the CLASS IfcBeam, that describes any type of beam, hosts various specific TYPES of beam, such as BEAM, JOIST, HOLLOWCORE, LINTEL, SPANDREL, etc). The standardised system of CLASSES and TYPES is fundamental during the import of an IFC as they are the programs’ way of finding the entities that they need. For example, a structures application will search for a series of classes and types (e.g. IfcColumn) in order to import, interpret and work from. Each CLASS is also assigned a default and standardised set of basic parameters known as P-SET. For instance, the CLASS IfcWall is assigned a P-SET that contains parameters such as U-value, Load-bearing, Sound insulation class, Fire behaviour, etc. This is a set of data relevant to that CLASS that will be displayed in viewers and worked with in programs that import IFC. Each IFC f

ile is assigned a MODEL VIEW DEFINITION (MVD); this is its function (what that IFC will be used for), so that its data is organised and optimised for that purpose. A structural MVD will mean that the IFC only contains information relevant to the analysis and calculation of the project’s structure. CYPE-Revit Interoperability Guide / 4 2.2 Characteristics of a Revit IFC In an IFC there are 3 types of element that Revit is capable of exporting according to the geometric operation with which they are generated: 1. Extrusions: of a straight extrusion profile. 2. Sweeps: through a direction vector. 3. B-rep: Boundary Representation. They can either be vertices with coordinates in space that join with the edges and form the object, or NURBS surfaces. The three previous entities are correctly represented in the three-dimensional space of the IFC and can also be used for model coordination jobs. Each element, independent of the way the geometry has been generated, will have its own

corresponding IFC class and type. For example, there can be a wall element of the class “IfcWall” that is a simple extrusion, but also an “IfcWall” that is a B-rep. In both cases the “IfcWall” could have exactly the same properties. However, it should be remembered that each software program has its own rules regarding the generation of geometry. In general, the simpler the geometrical definition of an element, the more possibilities there are that another application is able to recognise the entity and continue working with it. The easiest are simple extrusions, whereas B-Rep are the most complex entities. Due to the structure of Revit’s IFC exporter, when you export to IFC it will attempt to generate almost all of the entities as a simple extrusion profile. Only in cases where it is impossible to geometrically define them as an extrusion, the surface will be exported as a sweep, and in final instance, as a B-rep. All of this is especially relevant to the way in which y

ou model within Revit. Achieving a model which is capable of exporting itself entirely as a simple extrusion will greatly contribute to good communication with other tools, including CYPE’s suite of programs. CYPE-Revit Interoperability Guide / 5 3 Workflow Revit - CYPE 3.1 General settings The IFC format allows information to be exported from a specific application to other applications of other developers, in order to view and work with the information. The most important thing in the REVIT-IFC-CYPE workflow is the optimisation of the information that is exported to subsequent applications. This means that: 1. It is safest to export simple models, when you have the basic architectural elements relevant to development in specific applications (walls, partitions, slabs, doors, windows, etc). This does not mean that a detailed Revit model cannot be exported – section 4.1. Mapping settings details how to specify which entities to export to IFC. Nevertheless, exporting a simple

model is the best way to guarantee a fluid interoperability. 2. Model as much as possible according to the guidelines laid out in this guide. Each software program has an internal structure and logic designed for its correct operation, with different accuracy levels according to its function. Revit is a general purpose program, where there are various ways of doing things. However, it will be necessary to choose the work method where the structure of the entities is similar to the structure of the specialised applications. These applications require greater accuracy when carrying out calculations and code justifications of structures, energy analysis, acoustic analysis, installations etc. Finally, it must be kept in mind that CYPE has two types of program – those that allow the modelling of architectural elements (CYPECAD MEP, IFC BUILDER), and those that do not (CYPETHERM, CYPEPLUMBING, CYPELUX...). Exporting to the second type is a lot easier than to the first. If you want to t

As a general rule, the more complex the exported IFC is, and the more functionalities that the CYPE application has where you want to export to, the more accurate the model has to be to achieve the best interoperability. CYPE-Revit Interoperability Guide / 6 3.2 Open BIM plugin for Revit The best way to export to IFC to guarantee an optimal communication between CYPE applications is to use the free export PLUGIN, available on the BIMserver.center STORE. This PLUGIN facilitates the configuration of the IFC exporter integrated in Revit, allowing a direct link with our project in BIMserver.center. The default configuration of this plugin will function in the majority of cases, as long as the suggestions in this guide have been followed. You must keep in mind that the possible limitations in the exportation process are inherited from Revit’

s IFC exporter, developed by Autodesk. By clicking on COLLABORATE ON OPEN BIM PROJECT we have two options: 1. Select an existing project- if there is a project in BIMserver.center where we want to take the exported IFC we can select it by clicking on this option. It will open a pop-up menu with a list of our projects. 2. Create a project on BIMserver.center. We will be able to create a new project on the platform directly from Revit in a matter of seconds. In both cases, an IFC will be exported that is uploaded to the cloud, and will allow for collaborative working and synchronisation with other IFCs uploaded to the same project – both those developed in CYPE programs and those created by another tool which are connected to the project. When opening any CYPE application you can link directly to the project and its files and continue working as usual with the information you have generated in Revit. Furthermore, when the Revit file is synchronised with BIMserver.center, you will

CYPE-Revit Interoperability Guide / 7 3.3 Analysis of possible exportation errors On occasions it is possible that the import to CYPE programs is not as expected, and it is unclear why. When exporting the IFC with the PLUGIN and uploading it to BIMserver.center, you are generating a local IFC file that serves as a conduit between Revit and the cloud. You will find this file by default in C:\ bim_projects\ user_XXXXX\ proy_XXXXX (although this directory can be edited from the BIMserver.center synchroniser). There will be a folder structure that serves for organising the different files and establishing a good connection with Revit. From here, you can open the IFC file with any free IFC viewer (e.g. BIMvision free

viewer, available on BIMserver.center) and check that all the geometry necessary to carry out the analysis in CYPE software has been exported – if it has been exported in its correct position, if it has the correct properties etc. For example, it is essential that IfcSpaces have the 2nd Level Space Boundaries defined in order to carry out the energy analysis with this IFC model. Additionally, and as a general rule, the most difficult export is to modelling programs such as CYPECAD MEP or IFCBUILDER: however, in this case it will be possible to solve this problem within these same programs, remodelling the parts that haven’t been correctly exported. The goal is not to achieve an identical copy of Revit’s geometry in CYPE programs, but rather to obtain a model with the necessary and sufficient information to carry out the relevant analyses and calculations.

ble that determines the translation from REVIT native entities to IFC entities. This table can be found in Revit > Export > Options > IFC Options. For a correct export, you will have to ensure that the necessary entities for the desired calculation model and the correct equivalence between entities are exported. The following table defines which REVIT entities need to be exported to which IFC entities, depending on the applications to which the model is to be exported. The goal is NOT to reproduce the entire Revit building in IFC, but rather to extract from the model the necessary information to carry out certain actions with specific tools. The graph above shows the amount of information that travels in the IFC (vertical axis), and how much of this information needs to be interpreted as native by the different disciplines of the project (horizontal axis). Traditional BIM tools (Revit) are not capable of exporting the space boundaries (IfcSpace) needed, for instance, for accurate ther

However every day IFC analysis tools are improving and at CYPE we are working on a tool capable of interpreting this missing information to incorporate it automatically into the project. Alternatively, you can use the free BIM tool CYPE-Revit Interoperability Guide / 9 IFC BUILDER or CYPECAD MEP, that guarantee a model which exports the maximum information recognisable by the CYPE suite for this type of calculations. Alternatively, you can use the free BIM tool, IFC BUILDER or CYPECAD MEP, that guarantee a model that exports the maximum amount of information recognised by the CYPE suite for these types of calculations. CYPE-Revit Interoperability Guide / 10 4.2 Levels In Revit, it is common to work with several levels on the same floor – at least an architectural/ finished floor level, and one structural level. However, most of the analysis and calculation programs in the CYPE suite are desig

ned to work with only one level per floor – that of its specific function. To avoid an excess of floors in CYPE programs, it is sufficient to uncheck the “building storey” instance parameter for those levels that are not relevant for the analysis to be carried out. That way, those floors will not be exported and you will be able to continue working only with the necessary levels with the specific tool. Be careful when exporting to modelling programs such as CYPECAD MEP or IFC BUILDER – the levels that are not exported cannot be used as a reference for the upper or lower boundaries of the walls. Another alternative solution would be to leave these levels unchecked when importing the model to calculation programs. CYPE-Revit Interoperability Guide / 11 4.3 Rooms The rooms are one of the most important entities, since they are the basis for many of the calculations and analyses that can be performed on a BIM model.

sure their export and accurate calculation, by applying the following measures: 1. Deleting unplaced rooms and spaces. When you delete a room from any view in Revit, it is deleted from the 3D space but it remains present in the project. To completely delete a room in a Revit project it needs to be done from the schedule. In order to do this, go to View > Create > Schedule, and create a schedule/quantities table where you will include at least the area. The rooms that are not placed on the floor will have the value “not placed”. From here they can be deleted, removing them completely from the project. CYPE-Revit Interoperability Guide / 12 2. Adjustment of the upper room boundary to the lower edge of the upper slab. Currently, Revit’s IFC 4 exporter has limitations when exporting rooms bounded by floors and ceilings. As opposed to IFC 2x3, it is not able to correctly “trim” the shape of the room with its horizontal bounding elements. This means that after exporting, th

e IfcSpace will ignore its clash with the slabs. Therefore, to ensure that the volume of the room is correct when exported to IfcSpace, a higher negative offset equal to the thickness of the slab must be entered. This consideration is only necessary for the development of thermal and acoustic studies. CYPE-Revit Interoperability Guide / 13 3. Check that the volume of the rooms is being calculated. To guarantee that the areas and volumes correctly export to IFC, it is advisable to go to Architecture > Room and area, click and open the dropdown menu > Area and volume computations. Once you have accessed the menu for calculations of area and volume, the “areas and volumes” and “at wall finish” options should be checked. CYPE-Revit Interoperability Guide / 14 4.4 Walls It is advisable to observe the following guidelines to ensure that the walls are correctly exported from Revit to IFC, and that the entities are legible by CYPE software. 1. The use of upper and lower const

raints for slabs and roofs, avoiding the modification of the wall profile sketch. 2. It is recommended that the walls go from level to level and that there is a wall per floor. This is especially important when exporting to modelling programs like CYPECAD MEP o IFC BUILDER. Otherwise the import results in these programs may be unpredictable. 3. The use of the WALL OPENING BY FACE tool instead of drawing openings in the sketch of the wall. 4. It is imperative that the walls are a single integral element in layers- as is outlined in Autodesk’s official documentation. It is not recommended to work with exported models where each wall layer has been modelled as a separate and independent wall type/instance. 5. It is preferable to create linear walls instead of wall by face. If the export is made to non-modelling programs (like CYPECAD MEP or IFC BUILDER), it will also be possible to export more complex walls, with the limitations inherited from Revit's IFC exporter developed by A

The correct definition of the FUNCTION type parameter (exterior/interior) of all the walls according to whether they are enclosure or partition walls (for thermal or acoustic analysis programs). CYPE-Revit Interoperability Guide / 16 4.5 Floors The floors are usually defined by perimeter. As with walls and roofs, it is best to model trying to obtain shapes that can be generated in IFC by simple extrusion. To this end, it is recommended that: 1. Use the floor by definition of boundary lines instead of “floor by face”, although the last option will also be possible in non-modelling programs. 2. Sloped floors that exceed levels should be avoided. In this case it would be advisable to make an independent sloped floor in each level, with the meeting points of the floors being at the upper and lower edges of the respective levels. This is especially relevant when exporting to modelling programs such as CYPECAD MEP or IFC BUILD

Instead, for sloped floors, the definition of the family’s inherent slope arrow is recommended. CYPE-Revit Interoperability Guide / 17 4.6 Roofs For the same reasons stated in previous sections, it is important to model in such a way that the IFC file can read the entities as simple extrusion profiles. To this end and to optimise the best communication between programs, it is recommended to employ, as much as possible, the following modelling practices: In general: 1. Create the roofs from the “Roofs” group and not from the “Floors” group. This will allow thermal/acoustic analysis programs to be able to distinguish between both elements and correctly perform the calculations. 2. It is recommended to create roofs by footprint and not by extrusion. 3. Associate the roofs to levels to be exported

This slope entered in Revit won’t be useful data for further calculations and analysis. CYPE-Revit Interoperability Guide / 18 4.7 Links One of the limitations of Revit’s IFC exporter is the export of links to IFC. The exporter has many problems with the geolocation of links (correct export when coordinates are referenced to the Reference Point), and their correct relative positioning if they are moved or rotated. As for links where symmetry has been applied, the export does not work. Therefore, the best way to guarantee a correct and stable export if the project shares Reference Point Coordinates will be to bind all the links that you want to bring to IFC and export the unified project. This can be done in a separately saved temporary file whose purpose is the correct export to IFC. To attach, select the link and click

on Modify > Link > Bind. The binding of all the links can be difficult at times, since big projects can contain a great number of objects and geometry, and Revit is not capable of supporting many elements simultaneously due to excessive RAM usage. In these cases you must be bear in mind that the important thing is not to transfer the whole model to IFC, but only the elements relevant to what you want to do. It is therefore recommended to delete all categories that do not serve this purpose, optimising the file’s entities and being able to finally carry out the attachment of all the links. Even though the Open BIM plugin for Revit will try to unify all the links into one IFC file, binding everything will be the safest option if we face any issue regarding the model federation.

To avoid these possible issues and errors, a good practice is to create a temporary copy of the local file that is detached from the central file. This can be done by opening the file from Revit’s file opening manager, where the box “detach from central” must be checked. Ideally, the worksets will also be discarded. This temporary file will be needed only when exporting, and it only needs to be created once. Once the IFC file has been exported with the necessary entities and the correct import has been checked in the corresponding specific CYPE applications, the temporary detached .rvt file can be deleted. It is important to carry out the export with the free CYPE for Revit PLUGIN and following all the guidelines in this guide to guarantee an optimal interoperability.

Changes made in the CYPE applications will be synchronised when the linked IFC files are overwritten, and their updated information is transferred to the central model. CYPE-Revit Interoperability Guide / 20 4.9 Origin, base and survey points In Revit there are three origin or reference points: the origin point (invisible and linked to the survey point, the real centre of the file), the base point (circular, local project centre) and the survey point (with a triangle symbol, global centre of the project) This is especially important when working on projects that contain linked files, as it is very easy for such files to be moved from their federated position in the export process.

is one of the biggest limitations of Revit’s IFC exporter. In general, it is best to export using the survey point in order not to lose the georeferencing of the model. However, due to the limitations of Revit’s native exporter, this guide recommends using the survey point if linked files exist. The other solution is to connect all the links when exporting (in a temporary file whose sole purpose will be the generation of the IFC) and also export from the survey point. Otherwise the federation of the linked models will be compromised, and it is very likely that they will move from their correct position in the export process. CYPE-Revit Interoperability Guide / 21 4.10 Phases One of the limitations of Revit’s IFC exporter is that it only allows one phase to be exported at a time. In any case, the phases won’t be relevant for CYPE’s calculation and analysis programs. As such, the best and most stable way to export to IFC will be to delete the phases that have elements th

at we don’t need, and to connect the phases that do, leaving the project with just one phase. This can be done in MANAGE> PHASES. When we connect phases it’s important to check that no element information is lost –in particular, the rooms – and that in the Energy Settings and Revit’s IFC Exporter, the phase that we are left with is selected. This would only need to be done when exporting to IFC. In order not to lose project information, this can be done by previously saving the file in a temporary parallel copy that will only be used for export. At the end of the process we will be able to bring to Revit the different calculation IFCs generated with CYPE programs, and assign the linked IFCs to their respective phases.

ulation and automatic generation of the justification report. Furthermore, it will be possible to consolidate the information in BIMserver.center or in Revit via IFC. For good communication between Revit and CYPECAD it will be necessary to: 1. The columns will be exported as IfcColumn, which CYPECAD is able to import as native columns. 2. Model the slabs as Floors, which will be imported as boundaries that can be converted into native CYPECAD slabs at the click of a button. In CYPECAD the structural elements can be defined in detail (beams, columns, slabs) with their respective characteristics, as well as the stresses exerted on the structure. For an optimal communication between Revit and CYPECAD, this should be done through the free Open BIM plugin for Revit. Once the calculation has been completed the file can be exported from CYPECAD to IFC, which will contain the geometry, analysis data and justification report. Moreover, you will be able to obtain automated rebar plans for al

CYPE-Revit Interoperability Guide / 23 6 Installations 6.1 Calculation of general installations To calculate small or medium sized installations and automatically justify specific code checks it’s common to work with the CYPECAD MEP tool. From this program you will be able to resolve all of the code check sections related to energy efficiency, noise protection, fire, plumbing, sanitation, HVAC, solar thermal, lighting, electricity, telecommunications and lightning conductors. By exporting to IFC with the free Open BIM plugin for Revit and then importing the IFC by searching in the local folder C: > bim_projects > project folder > IFC, you can quickly redefine all the construction elements of the project and automatically generate all the required calculations and justification reports.

BIM workflow, extend the possibilities of CYPECAD MEP whose approach is more general. They offer the designer and engineer design tools that reach higher levels of detail and definition in installations of energy efficiency, fire protection, plumbing, sanitation, electricity, HVAC, noise protection, etc. Many of these applications have been custom-designed with particular products from specific manufacturers, and allow users to calculate specific systems with automatic justification of the corresponding application codes. Furthermore, the decentralisation of disciplines into more sophisticated applications makes it possible for several users to work collaboratively on the same project –with cloud synchronised tools for tracking changes, discipline coordination, clash detection and multiplatform augmented reality. The communication with these applications is similar to the case of structures – using the free Open BIM plugin for Revit. Simply export the architectural elements and the

spaces with their respective IFC Classes in order to be able to calculate the corresponding installation. Once the calculations have been carried out, they will be updated in BIMserver.center, where you can continue developing the project alone or collaborate with other users, or consolidate the information back into Revit. CYPE-Revit Interoperability Guide / 25 7 Energy calculation 7.1 Spaces Revit spaces are also exportable entities to IfcSpace, so you can work with both rooms and spaces in Revit and achieve their export to IFC in the same way. In any case, if both entities exist in the project it must be ensured that there is no overlap in the exported IFC; that is to say, the mapping sheet must be configured so that the spaces are not exported. To do this, go to File > Export > Options > IFC Options, and write “not exported” in the boxes referring to the spaces.
