New Project - Open Dynamo File with InstanceByPoint > Run > Error

As you can see from my screenshot, I have a dynamo file open with the three node-workflow to instantiate in Revit an 2d array of cubes. As I run the definition I get this error.

The only way to avoid this has seemed to be by replacing these components with new ones…

This has been the workaround, but it would be great to know how to fix this/if there is something that I’m doing wrong.


I need some input to reproduce this at my end.

Is this file created in old version of Dynamo 0.6.3?

Can you try running same file on top of family document. (right now you are running on Project document)

If possible share your files.



revitTEST_attractorPt0 fam_Box_6by6Hi Ritesh,

Thank you.

Hey Lv2311, thanks for sharing your data sets. I am able to download files and also able to reproduce your problem.

I logged a bug to track this internally. MAGN-3906

I will get back to you once it is fixed.

Note: If you use Construction Template then you can place your families to Project Document. The crash is happening if you use other three templates.

Thanks and sorry for the inconvenience.
