To open the revision selector, click the button with the “cube” on the top left of the screen in the 3D viewer.

The following topics will be described in this article:

In the models menu you can work with 3D documents while keeping the 3D viewer panel in full focus. Turn 3D documents on or off and choose which revision you want to look at.

The models menu can look something like this.
​

Find the 3D documents you are looking for by searching on part of their names.

To narrow down your search further consider searching in the content panel.
Here you might be able to search by other filters or find 3D documents that have not yet been linked to models or loaded in the 3D viewer.

See the 10 most relevant 3D documents.

Models - Displayed by default

See all the Ifc documents that have been linked to a model.

Your list of available models is based on the access setting of the document that is linked to that model.

3D documents - Displayed when loaded in

Load 3D documents from the documents page to display them towards the top of the list. See here which document formats can be loaded in the 3D viewer.

Load more
To load in more models click on the load more button at the bottom of the revision selector.

When the 2D button is green, the 2D view of that model is visible in the 2D viewer and loaded into memory.

When the button is grey the 2D view of that model model will not be visible and is not loaded into memory.

When the 3D button is clicked it will turn green.

The 3D view of that document will then be available in the 3D viewer and loaded into memory.

While the 3D button is green model objects that belong to that model will be available in the 3D viewer.

After a model has been loaded into memory the 3D button can be clicked again.

While the objects are not available in the 3D viewer, the document will still be loaded in memory. This makes it you can quickly turn on and off documents that you have previously loaded.

Unloading from memory
