As per the docs of dynamo primer solid.union joins the solid into one single solid but it doesn’t work like this in dynamo i have tried framing and columns and did solid.union it doesn’t make them one single solid ever after lacing set to cross-product.

Can you post your graph showing the preview data (expanded results)?

My guess is that your data structure is in a nested list, but we can’t solve what we can’t see.

I think the issue is you’re lacing with cross product. Solid union will join a list of solids. No cross product required, and ideally one list if you’re trying to join it all in one.

Try a listflatten before solid union…and as Gavin say no crossproduct needed…
