| − | You can either query an external IFC model by loading it via file picker or load the currently active IFC file by ticking off the <code>Load from Memory</code> check box.
| |
| − |
| |
| − | You can either use the pipette to select objects currently selected in the 3D view or using the [https://docs.ifcopenshell.org/ifcopenshell-python/selector_syntax.html Facet Based Selector Syntax] specify which IFC classes will be queried. For example, specify IFC classes manually like <code>IfcWall</code> or <code>IfcSlab</code> or you can use a comma <code>,</code> to select more than one class, like so: <code>IfcWindow, IfcSpace</code>.
| |
| − |
| |
| − | You can save your query as a <code>.json</code> template or load an existing template. Here's an simple example.

| |
| − | Finally, you can save the output to CSV with the <code>Export IFC to CSV</code> button. One usecase of IFC CSV is to quickly bulk edit many values in an IFC file. So after exporting to CSV, you can edit some properties and load them into your model again with the <code>Import CSV to IFC</code> button.
