Layer names (Rhino) to create Model Object Categories using Rhino.Inside?

Hi,

Since my first post, I found the ‘Organize Rhino Geometry into Revit Subcategories’ video:

I followed the steps and built a grasshopper file copying what was shown in the video:

My intention was to create sub-categories under the Revit main category ‘Casework’ that would make it easier to edit the object styles. The sub-categories creation has worked:

The problem is the import of the items referenced on that layer into Revit. The GH file shows a Revit component has been created:

Nothing shows in Revit:

If I ‘Select by ID’, an element has been created:

I’m hoping you’ll be able to shed some light on this issue as it’s been frustrating to say the least.

Thanks in advance,

Rob
