Custom User Field for the name of the parent 3d object?

I would like to make  a custom user field for resources that displays the filename of the 3D Object that it is derived from. How would I do this?

  • Hi Arpit,

    I'm just getting into UFs and how powerful they are. I got the formulas working to show my 3D object's name and immediate parent's name, but I can't get the root filename formula to work. Same error:
    Error: cannot parse UF in formula for UF[Root Filename] : Error: unknown element in formula starting [LEVEL_1.NAME ]

    Here's my UF window

  • Hi Gary, 

    Can you confirm if you are seeing the same colors in the Formula as well - 

    Try typing out the formula instead of copy/paste. Also make sure you are running this for the 3D OBjects, and not Resources.

    If everything looks the same as the screenshot, then I am not sure what the issue could be. You can probably remove all the data besides a few geometries and send over the SP file for review as well.

    Otherwise, I will recommend reaching out to

  • Hi Gary, 

    Additional to to Arpit's check item.

    Can you tell us what is your SYNCHRO build? Are you using Because the LEVEL_ command is only available in build. 

    If you use previous build, you can use PARENT.PARENT....  command and count how many level is the root level. 

    Best regards,

  • Ah, I am on Synchro 2020 Pro x64 which I believe is the latest version of a now dead product.

  • Hi Gary - what exactly did you mean by "a now dead product"? We released SYNCHRO 4D Pro recently in June, 2021. 

  • Hi Jacqueline, Thank you for taking a month to misread my comment and give bad information. Can you confirm the following statement is true?

    "Please note that SYNCHRO Pro as a separate product from 4D Pro is no longer being offered, but 4D Pro continues to support an .sp file-based workflow in addition to opening cloud-hosted projects from SYCNHRO Control."

    I found this on the descripton of a recent video on your youtube channel here:

    Going from Pro to 4D Pro is a huge price difference as well as involving many features that are simply never going to be used by our firm. Trying to push up this way is making us take a deeper look at your competitors.
