IFC Export Georeference Doesn't Match Model Georeference.
Mihail Rizov replied to Jack2022's topic in Site Design
Hi @Jack2022, Prior to Vectorworks 2024 Update 4, IFC model origin is always the User Origin. (Site Data, like Ref. Longitude/Latitude are for informational purposes only in the receiving applications) Best Regards, Mihail Rizov -
Hi @aage.langedrag, This is not a straight-forward process and the first step is to deliver IFC 4x3 support for export/import, default mappings and script/SDK (2024 Update 4). The next step is to integrate it in our libraries/content - this will happen in 2025 (not sure about the exact date). Regards, Mihail Rizov

Hi @Poot, All of the objects have IfcBuildingElementProxy or IfcGeographicElement assignments. And after removing IFC Data from Site Model-Nord 1, all 8 objects are exported. (There is no IfcSiteModel - maybe, you meant IfcSolidModel - this is not an entity, so it will not show up - please, do not use it)
-
.... This is the file for IFC4. Multiple Site Model to IFC4.ifc
-
Hi @Poot In your file all Site Models are assigned to IfcBuildingElementProxy. You have to select one of them to be your site (speaking for IFC2x3, as per the settings in your file). Just click on it and remove IFC Data (Data pane/Detach button) - in that way, it will have the default IFC assignment - IfcSite. (I selected Site Model-Nord 1, for example) Multiple Site Model to IFC.ifc

HI @Poot, According to Implementers Agreements (which are an addition to the documentation), an IFC file should have only one instance of site. (Please, see here - https://standards.buildingsmart.org/documents/Implementation/IFC_Implementation_Agreements/CV-2x3-141.html) When you export an IFC model, there is always site instance exported (it may have no geometry, but it's mandatory for the spatial structure and georeferencing). If you need more "sites" to be exported - they should be marked as IfcBuildingElementProxy (IFC2x3) or IfcGeographicElement (IFC4 and above) and you can use properties or property sets to describe them as sites. In order to export a site model with a geometry: - Check the option Export Site Model in Data tab/Export Options; - Assign a layer with DTM (or other object representing the site geometry) in Layer Mapping to Site (Vectorworks Story Name); In IFC2x3, IfcSite will contain both data and geometry. In IFC4 - IfcSite will contain the data/properties and the geometry will be in IfcGeographicElement. HTH and regards.

IFC ceiling grid made manual does not export in 2023
Mihail Rizov replied to ida's topic in Architecture
Hi @ida! It depends on the version you use - US release of 2023 SP7 is on Aug 22nd, but the release of localized versions depends on our distributors. Regards -

Hi @ida, This is fixed and will be delivered with the next updates of Vectorworks. Thanks and regards -
Creating IFC Custom Properties Sets from a xml file
Mihail Rizov replied to GatRed's topic in General Discussion
HI @GatRed, In 2023, custom property sets are saved in the Data Manager settings (data mapping settings). Saving and loading them in another project will do that. Regards, Mihail Rizov -
Hi @Hans-Olav, Sorry, there is no function for rotation - it can be done manually in IFC file directly (search for placement of the IFCSITE second vector (RefX) and replace the default (1., 0.) with the calculated vector. Regards, Mihail Rizov
-
Hi @Hans-Olav, You can shift your model by using the Data Manager: - Invoke Tools -> Data Manager; - Type IfcSite in Objects box; - Select IfcSite in the list below; - In the middle list (below IFC Data Sets), expand IfcSite; - Double-click on RefElevation - Define Mapping dialog will be shown; - From the popups, select Fixed value (Real) and type the desired vertical offset in mm (can be negative, if you have to dive your model); - Click OK, then again OK to save and close Data Manager and export your model; Regards, Mihail Rizov

toggle more options in IFC_ExportNoUI(path)
Mihail Rizov replied to matteoluigi's topic in Vectorscript
@matteoluigi, Please, do not forget to save the document after IFC Export. -
toggle more options in IFC_ExportNoUI(path)
Mihail Rizov replied to matteoluigi's topic in Vectorscript
Hi @matteoluigi, Yes, that was the intention. In order to setup layer mapping and options, it is not necessary to make an export - open IFC Export, setup all and press Save Settings. Regards, Mihail Rizov -
Can not map IFC Material properties
Mihail Rizov replied to arquitextonica's question in Troubleshooting
Hi @arquitextonica, There is something that is not very clear, it seems to me you're trying to workaround something else. Please, explain me the reason why the user will model a wall with exact materials - this is why all packages have a library of materials with all data/physical properties/etc. - and after that will want to override the properties of the material. If it is something different - the user should create another material with the desired data. So, simply my question is - why do you need to replace the original materials? (The name of the material is not just a text - it is unique. BTW, in IFC material assignment is not a property - it consists of material instances (material/material list/material layers/material constituents), auxiliary instances and relationships between them.) Regards, Mihail Rizov -
Can not map IFC Material properties
Mihail Rizov replied to arquitextonica's question in Troubleshooting
Hi @arquitextonica, "Material" is a quasi-pset that was introduced to allow the user to define materials for objects that do not have a proper material management. During the export, it is converted to material instances and relationships in IFC. (Later, the other purpose was Data Tag/Data Visualization usage) So, it is ignored for objects that have material assignment UI, like walls/slabs/roofs/columns/structural members. Regards, Mihail Rizov -
Can not map IFC Material properties
Mihail Rizov replied to arquitextonica's question in Troubleshooting
Hi @arquitextonica, From your post, it is unclear what kind of objects you're using (plug-in objects, custom objects, custom geometry, symbols,...). Please, send us a very simple file and an explanation what is your goal. Regards, Mihail Rizov -
Hi @zoomer, Thank you for your information. I'm attaching the IFC-exported file from our latest changes. A few things to note: - Please, do not attach IfcSite to whatever - an IFC file should have no more that 1 (one) IfcSite, it is added automatically (even if not present in the model) or it is the first DTM object in the layers assigned to Site in Layer Mapping/IFC Export dialog; - If you are not sure about IFC designation of an object - please, use IfcBuildingElementProxy. Another option is to choose Extended Vectorworks Model View (Export IFC Project -> Data tab -> Model View) - this will export any object that has 3D geometry as IfcBuildingElementProxy, so you don't need to bother with attaching IFC data; - When you attach IFC Data to a group - this means you want to create an aggregate IFC Entity - e.g. complex roofs/stairs/ramps can be created and exported to IFC in this way. In your file, there are multiple groups with IfcSite and many symbols with IfcSite inside - sorry, this does not make sense, so I detached IFC Data from your groups before the export. Regards, Mihail Rizov TEST_IFC_EXPORT.zip

Hi @zoomer, We are aware of that issue and we're working on it. Could you tell us did you draw all your objects in 2022 or the model was translated from 2021 or an earlier version? Thanks and Regards, Mihail Rizov

Hi @GatRed, This function duplicates the direct IFC syntax, like IFC.'IfcFurnishingElement'.'Name' - same as GetIFCProperty('IfcFurnishingElement.Name). Regards, Mihail Rizov

Hi @Arielus, Coordinates and elevation in IFC are given in the site (IfcSite). You may find these settings in IFC Export dialog, Site Data tab. Regards, Mihail Rizov
-
Hi @Laura Stone, Sorry, we can't try this, because we don't have the full model - we have only the excerpt you sent here 😉 Export Site model affects only the export of DTM object that is representing the site (and its layer must be mapped to Site story). Regards, Mihail Rizov

Hi @Laura Stone, I can confirm that assigning materials in Revit works only if the geometry is extrude/solid and not in case of surface geometry. IFC sends the geometry as is and in case of Aligned Slab, the object geometry is mesh (surface geometry). Regards, Mihail Rizov
