Adjusting geometry breaks array

I’m trying to duplicate an extrusion using Curve Array in GH, and finding that adjusting the geometry of my extrusion breaks the array:

Before adjusting geometry:

After:

This is using R8. Any ideas?

3. Attach minimal versions of all the relevant files

Hi Andrew -

Rhino 9?

At any rate, when you select the first object in Rhino, the command line states:

1 closed extrusion added to selection.

When, in Rhino, you modify that object by moving an edge, the command line will read:

1 closed polysurface added to selection.

In Grasshopper, you use the Extrusion parameter to reference the original extrusion object, but when this is modified and becomes a brep, that parameter won’t be able to reference that new object. Use the more general Brep parameter instead:
