+- [x] A **lock system** should be put in place to allow two different scenarios:     
   1. The user wants to work strictly with IFC objects (strtict mode) or 
   2. The user wants to mix IFC and non-IFC (FreeCAD-only) objects (hybrid mode).

 - [x] A better **display mode** that allows to load all files the same, fastest way. That display mode should handle edges and transparency properly, so there is visually no more need to load the object shapes (heavy) on file load.

-- [ ] **Refine the lock system** so it handles the following scenarios: 
-  1. There is no object in the document, or only IFC objects. Locking and unlocking should happen with no needed user interaction
-  2. There are non-IFC objects in the document and the user wants to lock the file. The user needs to decide what should happen with the non-IFC objects.
+- [x] **Refine the lock system** so it handles the following scenarios: 
+  1. There is no object in the document, or only IFC objects. Locking and unlocking happens with no needed user interaction
+  2. There are non-IFC objects in the document and the user wants to lock the file. The non-IFC objects are converted. This is fully undoable. [b739b77](https://github.com/yorikvanhavre/FreeCAD-NativeIFC/commit/b739b77a7068fe80c92481c519cafa9fb9b76431)
 - [ ] **Handle project creation**: At some point along the project development, users typically want to "go IFC". They should be halted, be asked which IFC version they want to use, and if they want to work in a locked or unlocked environment.
 - [ ] Create an **advanced external reference object**, that is able to handle not only FreeCAD files but also IFC files and possibly other formats too, such as DXF or mesh formats like OBJ, if possible, based on [App::Link](https://wiki.freecad.org/App_Link) structure.
