Short Answer
Yes, component assignment is largely automatic. When you import your IFC model or create a version, the 3D elements are automatically grouped, and each group is assigned a suitable default component from the vyzn catalog. You then review this pre-assignment in the component mapping and override it where needed.
Why It Matters
The automatic pre-assignment is a starting point, not a fixed result. You do not have to assign every 3D element manually; instead, you review the assignment and replace it wherever it does not fit your project. Since the default components come with KBOB-based environmental data, you start with a usable data foundation right away.
How It Works in vyzn
- When you import your IFC model or create a version, vyzn automatically groups the 3D elements according to SIA 2032 – for example, exterior walls above/below grade, interior walls, floor slabs, storey floors, roof, windows, doors, columns and beams.
- The grouping is based on the IFC element type, the location relative to the insulation perimeter, and the position (e.g. against the ground).
- Each group automatically receives a suitable default component from the vyzn catalog with KBOB-based environmental data. Currently, the default components correspond to a solid construction method.
- In the component mapping, you review each group and override it conveniently via product selection.
- In addition, you can choose how the elements are grouped: by element name, IFC type, SIA 2032 groups, via AI-based "Deep Auto" clustering, or by any IFC property.
Practical Example
You import an IFC model, and vyzn automatically forms groups according to SIA 2032. The groups are pre-assigned default components in solid construction – for example, a concrete facade with an external thermal insulation composite system (ETICS) for exterior walls, a flat slab for storey floors, and triple-glazed windows for windows. If a default component does not fit your project, you replace it in the component mapping via product selection.
Frequently Asked Questions
Is the automatic assignment binding?
No. It is a starting point, not a fixed result – in the component mapping you review each group and override it via product selection.
By which criteria can I group elements?
You can choose the grouping: element name, IFC type, SIA 2032 groups, "Deep Auto" clustering, or any IFC property.
Which environmental data do the default components include?
The automatically assigned default components from the vyzn catalog come with KBOB-based environmental data.
