Preparing & uploading models

What is a project in vyzn? A project is the top-level container in vyzn that groups related buildings. → What is a building in vyzn? A building is a structure within a project. It contains one or more variants. → What is a variant in vyzn? A variant is a planning state of a building with its own models, assignments, zones, and calculations. Multiple variants of the same building can… → How are project, building, and variant related in vyzn? In vyzn, the project is the top-level container that groups related buildings. A building contains one or more variants — each a planning state… → How does vyzn calculate the project-specific thresholds? The thresholds are project-specific, not fixed table values. Per zone, the formula is: base value B × zone area A ÷ EBF. The rows are summed to… → What level of detail should my models have? Less is more: simple models speed up upload, processing and variant studies. Ideal is a lean model that still contains all relevant components –… → How can I isolate or hide individual elements in the viewer? Right-click an element in the viewer to run actions such as "Isolate". While holding the Ctrl key, you can also draw a selection rectangle to… → How do I create multiple variants that I can compare? In vyzn, variants are technically versions of a model: you create them via the «+» icon, choosing between «Variante erstellen» (create variant,… → How long does it take to upload a model? Uploading a model typically takes 3–9 minutes. The exact duration depends on the size and complexity of your model. The process is being… → Can I import zones and rooms from IFC (IfcSpace/IfcZone)? Yes – vyzn imports rooms from IFC (IfcSpace) directly during import, including name, storey, gross floor area and volume. You can see them in the… → Can I select local climate data or weather stations, and which locations are available? Yes — when creating or editing a building, you select the appropriate climate station in the "Weather station" field. For Swiss locations, the… → How do I update my model with the Replay function? The Replay function reuses the settings you have already made when you re-integrate a model, instead of starting from scratch. Open "Re-integrate… → How do I manage multiple variants without losing component and material assignments? In vyzn, each variant of a model carries its own component and material assignments. To make sure nothing gets lost, duplicate variants instead of… → What requirements should my model meet? Ideally, you provide an architectural design model as an IFC file (IFC 2x3 or IFC 4) containing the most important building elements such as… → How do I handle IfcBuildingElementProxy elements? IfcBuildingElementProxy elements are not lost during IFC import, but by default they end up in the catch-all category "Building element proxy" or… → Do I have to start from scratch every time I have a new model? No, you do not have to start over. In vyzn you plan iteratively across all phases: work you have already done, such as component assignments,… → How do I manage zones in vyzn? You manage zones centrally in the zone management area: this is where you create, edit and delete zones and assign elements to them via… → What kind of 3D models can I use? You can use 3D models in the IFC 2x3 or IFC 4x format (regardless of the CAD tool, e.g. ArchiCAD, Revit, SketchUp, Vectorworks or Rhino). You can… → Are there modeling guidelines or naming conventions I need to follow for the IFC export? No, vyzn does not impose a binding, documented modeling or naming guideline – the IFC import is deliberately tolerant. However, the cleaner the… → Can I combine multiple models (architecture, HVAC, structural)? Yes, you can keep several IFC models per building, for example architecture, structural and HVAC. The uploads coexist and a new model does not… → What should I look out for when exporting a model from CAD? Export your model with the unit of measure set to "meter" and without IfcBuildingElementProxy elements. Disable the option "Split multi-layer… →
