Short Answer
Use the «Replay» function. When you import a corrected or updated IFC into an existing variant, «Replay» automatically transfers the groups you have already created and the assigned materials to the new model. So you do not have to group and assign materials to all elements again.
When to Use This
Whenever your IFC model changes (for example a new planning status or a correction) and you want to keep the work already done in the variant (groups and material assignments) instead of redoing it after the swap.
Step-by-Step Instructions
- Open the variant in which you want to swap the model.
- Start the model integration and switch to «Advanced» mode.
- Select «Replay» and upload the corrected or updated IFC.
- «Replay» automatically transfers your existing groups and material assignments to the new model.
Expected Result
The new model is active in the variant and your groups and materials are preserved. Elements that remained the same in the new model are automatically reassigned. You only have to group and assign materials to newly added elements.
If «Advanced» mode or «Replay» does not appear for you, contact vyzn Support (support@vyzn.tech). We enable the function or re-import the model via «Replay» for you.
