Short Answer
If your model appears "zoomed far out" when opening, the cause is almost always the model itself: the IFC contains large coordinate offsets because survey or coordination points are located far from the origin. The "Home" function in the viewer toolbar immediately re-centres the camera on the model; the clean solution is an IFC export in which the model sits close to the origin.
Issue Description
When you open a model, the building looks tiny and far away, as if the viewer had "zoomed far out". The viewer places the geometry exactly where it is located in the IFC — with large coordinate offsets, this is correspondingly far from the origin.
Signs of This Issue
- The building appears tiny and far away when the model is opened.
- The model contains survey or coordination points located far from the origin — often visible as triangles.
Root Cause
The IFC contains large coordinate offsets: survey or coordination points are located far from the origin. The viewer places the geometry accordingly far from the origin — as a result, the building looks tiny and far away when opened.
Step-by-Step Solution
Immediate workaround in the viewer:
- Click the tool button (wrench icon) at the bottom right of the viewer to show the viewer toolbar.
- Click "Home" (the function for resetting the view). The camera is re-centred on the model.
Clean solution before upload:
- Export the IFC so that the model sits close to the origin: remove the large survey/coordination point offset in your CAD software, for example via the project or base coordinates.
Common Mistakes
- Only resetting the view: for heavily offset models, "Home" helps only to a limited extent because the large offset in the IFC remains.
If the Problem Persists
Contact support — we can often correct the offset for you before the model is imported into vyzn. We are happy to take a look at your IFC.
