Rhythm - Workset.Create Not Working

Hi Guys,

I was trying to find a way of creating workset through Dynamo and found few custom nodes for making worksets. Tried all of them and return in “Null” . I’m not sure what I’m doing wrong and read an old post here : http://dynamobim.org/forums/topic/rhythm-workset-create/. Based on that my system should work with this node.
I’m running revit 2015 R3.

Can anyone suggest solution for this ?


Hi @Hagani_Ginting ,

FYI, Workset.Create method was introduced in Revit 2015 (R2) http://thebuildingcoder.typepad.com/blog/2015/02/revit-2015-r2-and-the-read-write-workset-api.html

Hi Kulkul,

Thanks, but I’m pretty sure I’m using Revit 2015 (at least it shows as Revit 2015 on desktop shortcut), isn’t that considered as Revit 2015? Also checked the version and running R3.

Your currently using below R2 Version. For more information on versions and updates refer here https://knowledge.autodesk.com/support/revit-products/troubleshooting/caas/sfdcarticles/sfdcarticles/How-to-tie-the-Build-number-with-the-Revit-update.html


Ahhh I see…

Thanks a lot, will try again once the system updated.


@Kulkul, Hi Kulkul

I’ve updated my system to the latest build and still the node came up with "Null’. Do you have any idea whats going on here ?


Just checked, it’s working. Grab python script from workset.Create node, connect to flatten and paste output here

@Tomasz_Puchala Hi Tomas,

the error came out as per below :

Warning: IronPythonEvaluator.EvaluateIronPythonScript operation failed.
Traceback (most recent call last):

Hi @Hagani_Ginting

You need to update which is (Subscription only release) Release 2.

@Hagani_Ginting, you need to be on a release that includes R2 as indicated by @Kulkul.

This method was added to the API for the mid year Revit 2015 release, for subscription customers only. The other part that adds difficulty to this is, you will have to uninstall and reinstall if you installed the wrong version.
