In response to this post from two years ago, I’ve fixed the issue that the @varunbose was having when trying to export multiple NWC’s.
For what it’s worth I’ve been able to add some functionality to the graph as well as rewrite most of it into Python.
Intended experience
After running the script, the User is presented with an input dialog window to specify two variables:
Search String (searches all 3D Views for Name.Contains(Search String))
Output Directory Location.
A Summary Dialog will present itself to the User (at end of script) with a click-able output Link, as well as a list of all Views that had attempted to export.
Brief Explanation
The Dyn exports NWC(s) for each view that it finds, to the specified Directory Location.
Then a Revit UI summary Dialog pops up with a link to the Directory Location, and reads off the list of all views that it attempted to export (if a view is void of content then it does not export an NWC for that view.)
Issue
It runs fine on my machine, however when I sent a copy to another machine and attempted to run it, it did not actually export any NWCs. It showed the Summary Dialog just as it should have (running through the Dynamo Player.)
Work-around
I had to go into the editor and add/subtract an input to the NWC_Export python node, then it ran successfully.
Query
Has anyone else run into this similar issue? If so, have you found a work-around? We’re running Revit 2020 and Dynamo Revit 2.3.0.6270
In previous revisions I had combined most of the nodes into one single Python node, but I was having reliability issues with that configuration. I’ve since pulled the Python node apart as well as isolate the Python nodes out of the individual Data-Shapes Multi-Input nodes so that other users won’t need to install any additional Packages (temporary work-around) for the Dyn to run. I don’t know if that is upsetting Dynamo for some reason.
I’m now trying to get the GeniusLoci.ExportNWCinDocument Node working, but I think there is something wrong with the code.
Traceback (most recent call last):
File "<string>", line 77, in <module>
File "<string>", line 27, in ProcessParallelLists
File "<string>", line 27, in <lambda$4780>
File "<string>", line 59, in ExportNWC
TypeError: expected NavisworksExportScope, got NoneType
Above is the output that the Python Node is giving me.
My Dyn seems to be working as intended, it’s just the actual Python Nodes themselves that have been giving me consistency issues. I may try throwing those problem PyNodes into their own Custom Nodes to see if that will help anything, but I’m trying to get it working consistently without relying on outside packages (if possible.)
Good morning. I am trying to get this to work with being able to export to DWG and NWC at the same time. I have always gotten then DWG to work but the NWC does not work in player and is spotty at best in Dynamo. Any help would be great.
I am aware of this issue which seems to be happening with every Navisworks export node that I have seen.
You may need to switch between false and true of the “RunIt” input before the export begins.
The script of the Export NWC in Document seems correct to me when I refer to the Revit API and the same code in a C # addin works fine but Dynamo seems to need an additional transaction.
