Uploading a model to the IFC web server

User access:

To upload a model to the dRofus web viewer, full Model server access rights is required. Please contact your administrator if you wish to upload a model and do not have the necessary rights.

Upload model

  1. Log into the dRofus web. Read more dRofus WEB access

  2. Select “Model Settings” on the left. When no model is uploaded, the only option is to create a new model.

  3. Set “IFC configuration”. Read more in the next section.

  4. Navigate to “Upload IFC Model” and click on “Select”. A window will appear

  5. Select IFC-file from the computer.

  6. Use the tick box to select if “Rooms are included from model” in the IFC

  7. Select Upload

Once the task is completed, a notification will appear beneath the model stating "Processing is complete." Subsequently, the uploaded files will be displayed in the following manner:

Please be aware that models - especially large ones - take a bit of time to upload. First the file is uploaded to your dRofus server, then from there to the Catenda IFC (BimSync) solution. Then, the model is processed meaning all fields are interpreted. All of these take time, but you should wait until all are finished before you go on.

Matching keys in dRofus and IFC

To be able to see the dRofus data and the geometrical model as one integrated whole, you need to set up the right keys for matching on both sides. To do this, click on the tab "IFC configuration". 

Here, you should be able to select the field in dRofus that should match a field in the IFC. Ant of the Room Properties that are defined for the project on the dRofus side can be selected - on the IFC side you can choose any field you want as long as you know the name (select "custom" as shown below, then type in the names).

If you don't know what the field you want is called, save and click on a room in the model. Then choose to see "IFC data"

on the room, and you will see the content of the IFC with the labels used...

When you think you have the right keys for the room, try to run a "match test". This will check the model to see how many rooms are matched using the chosen keys. If you are unsure of what fields to use, you can also choose to "get suggestion" - this will look through the ifc model and find likely candidates.

For the occurrence matching and the item matching the process is the same, though you have somewhat less help. To find matching fields, we recommend using a tool like Solibri to find what fields there are in the ifc. If the IFC file contains no matching fields to those you have in dRofus, you will need to do a new ifc export (or dRofus update from the model to get the keys into dRofus).

When this is done, you should be able to set a 2d floor plan of your model on the right side, like shown below.


Once the model is opened, for example for rooms, you should make sure you have included the "Match" column to your list, to be able to see which objects are linked and which are not. The easiest way to do this if you don't see it in your view, is to choose add/remove columns, then choose "Restore default". Match is one of the columns in the default setup for both rooms and occurrences.

Open model viewer

  1. Select "Viewer" icon, in grey.

Note that you need at least 3=read access to model server to see the Viewer icon

If a model is uploaded it will be displayed.
