Solid.byunion throwing error

The error shows up when toposolid has complicated surfaces, is there a way to fix this
Thanks

I have rhis issue with topo solid only ,when i use floor all is good…

As noted in the other thread: anyone who wants to help needs an RVT with a dataset to reproduce the error, and your graph to do the same.

Provide a simple RVT to produce the problem (ie: two topographies with the minimal amount of points to cause the issue), and an indication of the first specific warning - both the location and text.

Hello,
I am currently working on a cut-fill script and have encountered an issue that I could use some assistance with. I am using the solid.by union node in Dynamo to perform a union operation on a list of solids generated from the TopoSolid. However, this particular node keeps throwing an error, and I’ve been unable to resolve the issue.

To troubleshoot, I attempted to create floors from the same TopoGeometry, thinking that the TopoSolid might be causing the problem. Surprisingly, I encountered the same error during this process. Additionally, I experimented with flattening the list of solids before feeding them into the solid.byunion node, but unfortunately, that did not yield the desired results.

I’m reaching out to seek your expertise and advice on how to resolve this issue. If you have any insights or suggestions on alternative approaches, I would greatly appreciate your input.

Thank you in advance for your time and assistance.
