Hello @spindeli! Thank you very much for sharing. May I ask if you could, please, share either the place or more details that could help us reproduce?
Thank you again!

the errors can disappear when you rotate or move object sometimes. Also error appearing sometimes on new parts you creating and when you try to union balls

also there is a little more info in this topic

Hey! Thanks for reporting this issue. Can you enable the “Studio Solid Modeling improvements” beta and check if these errors still persist?

The error is gone, but instead of unioning normally, it turns into something weird.

Before Unioning:

After Unioning:

Hmm @spindeli I’m glad the first issue is fixed but We’d really like to take a look at the problem if you could forward a RBXL file for us to try to debug it? Feel free to PM @pho01proof or @BelgianBikeGuy (or any Roblox employee responding here) if you don’t want to share it publicly

this is the example model that keeps bugging

Also for future, this is not only model that bugging, ALL ovals, ovals unions and rarely some other normal parts bugging a lot too.

CSG error -15 mainly happening because of cylinder parts and cylinder unions

And it keeps bugging on every games i’ve made or just new places
