The Update IFC Model Dialog Box
If necessary, edit the names of the old and new IFC model in the object tree to distinguish which model is which. Select the object types to be imported from the new model.
Updating the model proceeds in two steps in the dialog box.
Phase 1
- Existing model
- The title shows the date of creation of the IFC model.
- Updated model
- The title shows the date of creation of the IFC model.
- Import parts deleted from Vertex model
- If you want to re-import the parts you deleted from the old IFC model, select Import parts deleted from Vertex model.
- Object Types
- Select the object types to be imported from the new model. If you have imported only some of the floors from the old model, only the floors in question will be imported from the new model as well.
Click OK to proceed to the next step.
Phase 2
- Existing model
- The title shows the date of creation of the IFC model.
- Updated model
- The title shows the date of creation of the IFC model.
- Changed / Deleted / Added / Possible pairs
- The table shows parts that are different from the old model in their own tabs. All the other parts are hidden in the model window. You can show and hide parts in the object tree while the dialog box is open.
- Changed - Click a row in the table. The program shows the old version of the part in the model window. Other parts will be hidden. Double-click a row. The program shows both the old and the new version of the part.
- Deleted - Click a row in the table. The program shows the deleted part in the model window.
- Added - Click a row in the table. The program shows the added part in the model window.
- Possible pairs - The new IFC model may have parts that are otherwise similar to the old model, but for some reason their unique identifier (GUID) has changed. In this case, the program interprets that the part has been removed from the old model and added to the new model. The part is shown on both Deleted and Added tabs with the note Has possible pair. You can confirm that this is the same part, regardless of the changed ID, by selecting the part on the Possible pairs tab and clicking Confirm Selected. After this, the selected part is shown on the Changed tab.
