    Hello JMB,
    please have a look at this post https://docs.unrealengine.com/en-us/...asmithMetadata
    It shows how to organise your metadata in Revit, how they are carried inside Unreal and how to retrieve them using blueprints.

    You ll also need to create a widget blueprint to contain the metadata and place it in your scene https://docs.unrealengine.com/en-us/...reatingWidgets

    Finally you ll have to do a piece of blueprint that will do the following:
    - On click, do a ray trace to know which actor has been selected. https://answers.unrealengine.com/que...to-target.html or please have a look at the existing product viewer/multi viewer templates.
    - Refresh your widget blueprint, used to display metadata, with information related to the selected actor. https://docs.unrealengine.com/en-us/...dgetBlueprints
    - show your widget blueprint, used to display the metadata information: you can choose make its position fix and always have the information in a corner such as shown in the video or you could also make your widget a 3d element and place it in the scene (near the hit point from the mouse click)

      THX for your answer Flavien,

      Now, I have all the steps to reach my objective

      Unfortunate that this exemple is not present in the new version of Unreal Studio. Lots of people working in the BIM (Building Information Modeling) is interested by this fonction.

      The new functions of 4.21 are great, Good work.

        Hi!

        I digged up an older project with something that would get you started. Can you access this link?

        https://epicgames.app.box.com/s/mh1s...dgiqrf3jpqkdyi

        I contains a project with revit data imported from 3ds max and a BP widget to display it on screen at play time.

          Exactly that I looked for to begin my project. I start to understand the nodes, step by step.
          Thanks for the gift.
          See you later.

            This Project helped me a lot too, Many Thanks, but i'm wondering if you can help me achieving the same result and callout to use for the VR Controllers.
            As I'm producing this project for desktop and VR and i want the callout function to show in both modes, not only with just the cursor click.
            Thanks in advance.

              and I'm also wondering if there is a way for the callout to show different metadata keys not just the one specified in Blueprint which was "Family_and_Type", I can imagine lots of scenarios but was asking what is the shortest one with least effort.

                  Where is the file? It seems to have been removed. Would love to take a look at it.

                    Hi !

                    I would be interested too in the construction of something like in the topic image of this post

                    But the file given by pf_breton seems to be inaccessible or has been removed.

                    Is there a possibility to access it or have it again ?

                    I've made some searches but no favorable outcomes this far.

                    Thank you all !

                      I have not found anything helpful either even though I have read through the documentation. I want to control revit object visibility based on values in the metadata

                        Actually I'd like to check out the file too if it can be made available again

                            Hi, thank you for the sample file, I am however finding it difficult getting around to using this. I've loaded in my exported datasmith file into the project and the metadata shows on the details tabs. However when I click 'Play' these doesn't show up when selected.
