To see an overview of the revisions in a model, go to the models page, and click on a model. You will then be directed to the overview page that belongs to that model.

The model revision overview shows us the model revisions present in the project. By clicking on a model revision one will be directed to the revisions page. One can then click on "Import" and upload a new revision model.

The following topics will be described in this article:

If you are an administrator or have gotten access to either creating models or downloading and exporting models in project settings you will see some buttons on the top right of the model's page.

Click here to read more about what each action does.

You will be able to find information about the model its right information menu. This menu can be found by clicking on the "i" icon on the top right of the page.

Click here to read more about what kind of model information is available.

Click on the pencil icon to change the name of the model

If there are no revisions in your model yet, you will be able to click on browse to import your first revision.

You can also drag & drop to import a new revision or use the new revision action in the existing item actions menu.

Access required: uploading model revisions from in project settings

This is done by choosing an IFC file from your hard drive.

Although other filetypes can be previewed in the documents section, only IFC files are accepted in the models section.

Click "send" to start the upload process.

When the process is complete Catenda Hub analyzes the IFC file and generates the geometry in the background. For large models it can take some time before the file is ready to be worked on in the viewer. If you wish you can exit Catenda Hub, geometry generation happens uninterrupted anyway. When importing is complete a notification will pop up in the menu bar in Catenda Hub and additionally an email will be sent to you stating that a new version is uploaded to a model for which you have access.

In the past you used to be able to add comments (brief explanation to the project participants about what is new in the revision being uploaded) to model revisions.

If these comments were added you will still be able to see them by clicking on show comments.

It is possible to open specific models in 2D and 3D by clicking on their respective buttons.

Click on the download button to download the latest revision of a model.

Access required: Read access to the document-model

When you open up Catenda Hub you start with fresh memory.
As soon as you load a model in 3D, whether this is via the models section, documents section or 3D viewer revision selector, the model will be in memory.
Even if you close the 3D viewer or click on 3D to disable the model again.
This makes it so that if you would click on 3D again next time, your model will be enabled a lot quicker!
The first time it might take some time to load into memory but then you can easily turn it on and off.
The model will stay in memory until you refresh the page upon which all models get unloaded.
​
One drawback of this is that, as you have noticed in many intensive Japanese projects, the browser cannot always handle having all these models loaded in memory.
If you notice performance is getting slower because your browser is close to the memory limit you can open up the model overview for models you have previously disabled and see the following message:
"This model is hidden but still loaded in memory. To free up some memory click here to unload the model:"

Here you can and click on unload in the message of your screenshot.
​
It can be hard to remember which models you previously loaded and it is pretty fast to load in models so If you are close to the limit I would recommend you refresh the page and open up the models you want instead of going into each one and unloading them.
