Central model and linked model

[venika_saini]

Hello, 

I have recieved a file from our client which is being modelled in 2019 Revit version, and we use 2023 version. As soon as the file opens, it immediately starts upgrading to 2023 version which leads to loss of families and elements moving off axis causing inaccuracies. Moreover, changes made cannot be saved as it calls for Authorization error.

I tried with dettaching the model from central, however it did not work well, tried to manage revit links into the local model which again did not work. 

Here the Architecture is not visible as well, in 3D but is visible in floor plans. Checked with visibility and graphics, view range, Discipline everything seems fine in properties but no luck! Please Help

If you are collaborating with the architect, you should be using the same version.

Is this so?

If you don't have Revit 2019 and your client doesn't have or want to upgrade to Revit 2023 then ask them to export to IFC and link the IFC in your Revit 2023 model.  Do the the same if they need to link your model in theirs.

Based on the information you have provided, it seems that you are encountering multiple issues with upgrading a Revit model from a 2019 version to a 2023 version.

In order to address these issues, you can try the following steps:

1. Create a backup copy of the original file before making any changes to it.

2. Verify that your 2023 Revit version is fully updated and has the necessary service packs installed.

3. Try repairing the Revit installation by uninstalling and reinstalling the software.

4. Try opening the 2019 version of the model in the 2023 version and upgrading it in small increments, checking for any issues after each upgrade.

5. Check if the file has any errors by using the "Audit" command in Revit.

6. Try importing the file into a new Revit project and linking it into your current project.

7. If the file still contains errors or missing elements after following the above steps, you may need to contact Autodesk support for further assistance.

It's recommended to use the same version of Revit for central model and linked model, and to perform regular backups to avoid loss of data.
