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

Hi Gary, 

Please try using the following User Field Formula - 

3D.LEVEL_1.NAME 

Hi Arpit, I tried that and got an error:
Error: cannot parse UF in formula for UF[Parent Obj 2] : Error: unknown element in formula starting [LEVEL_1.NAME ]

Gary, 

Can you please upload a sample SP file that I can test the formula out in?

Even screenshots of what you are trying to achieve and how your Resources are set up will help as well.

I can't share due to security and size limitations, but here's my situation. I had to make modifications to a revit model and used AutoCAD to split many objects at once and exported as DWG. This lost most of the BIM information so to try and organize the 3D objects and/or resources, I'd like to be able to see in a user field for either what the AutoCAD layer name is (immediate parent, here it's A-COLS-1) and/or the parent file name.

Thanks for the additional info, Gary.

You can still use the following code to get the root parent file name, though remove 3D when working with 3D User Field - 

Here's what this will look like -

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 synchrosupport@bentley.com

Hi Gary, 

Additional to to Arpit's check item.

Can you tell us what is your SYNCHRO build? Are you using 6.4.1.2? Because the LEVEL_ command is only available in 6.4.1.2 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 6.3.2.0 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 6.4.1.2 recently in June, 2021.
