Toposolid Error: "An error occurred during the sub-divide action..."

[Dean Camlin]

I hate this error!
"An error occurred during the sub-divide action. The sub-divide can not be completed."
It gives me no information to allow correction. Just "Too bad, Bub!"

An error occurred during the sub-divide action message in Revit (https://www.autodesk.com/support/technical/article/caas/sfdcarticles/sfdcarticles/An-error-occurred-during-the-sub-divide-action-message-in-Revit.html) says it's an error and Autodesk is looking into it.
2024 Toposolid error when attempting to split (https://forums.autodesk.com/t5/revit-architecture-forum/2024-toposolid-error-when-attempting-to-split/m-p/11944954#M390392) might have a cause ("it seems that a sketch cannot be created if it cuts through the middle of an elevation point.") and a possible solution " If I use pick lines and offset them 1/8", then the sketch can be created."

It's worth a try. I hope that helps.

PS. Both posts were made before yours, so search the text of your error should have brought them up. That's all I did.
