Load IFC or FRAG
Purpose
Open a model file into the viewer.
When to use it
Use this at the start of a session or whenever you want to add another model to the current workspace.
Where to find it
Top toolbar: `Load` button. The structure panel can also add another model.
Main options or inputs
- Accepted formats: `.ifc` and `.frag`.
- `.frag` is the preprocessed fast-loading format generated by ExyViewer.
How to use it
- 1. Click `Load` and choose an IFC or FRAG file.
- 2. Wait for the viewer canvas and structure tree to populate.
- 3. If you are working with multiple models, use the structure panel to unload or add more files.
Expected result
The model appears in the scene, becomes available in the structure tree, and its data can be used by the analysis panels.
Notes and limits
- A model must be loaded before visibility, markup, IDS, clash, classification, drawing, or reporting tools become useful.
- FRAG files are intended for faster repeat opening, not for authoring changes back to IFC.
Best practice
If you review the same large file often, export a FRAG version once and reopen that for later sessions.
