Anyway to link the CAD from ACC cloud file?
Same script is ok for local file, but fail in accessing the ACC cloud version.
Hi,
you must use the folder link via Desktop Connector it seems to me that there is no other solution to date (for non-cloud files)
Is there any chance that i can access via GUID or acc folder path of the dwg file in ACC via dynamo / code?
There is no API call to generate the link to an ACC path at this time, even if you have the cloud path.

Here is a good cheat! : )

The acc_local_path is a ‘best educated guess’ based on the file name and project extracted from the ACC docs.
If the boolean input in in[1] is False then it strips the extension. Handy for writing out e.g. excel files same name as project/family file without the extension. (How I organize associative content)
The code block:
preferred = IN[0];
fnName = IN[1];
ext = IN[2];
loclFp = IN[3];
central = IN[4];
accHTTP = IN[5];
docsFp = IN[6];
OUT = [preferred, fnName, ext, loclFp, central, accHTTP, docsFp];
Man how I wished BlueBeam did this for figuring out output paths!
I would upload the DYF but can’t as my account got munched when I left WM.
