Cell Fracture creating a block from a curved surface

So I’m trying to use the cell fracture add-on to destroy a curved wall.

However, when I apply the modifier, I end up with this?

I’ve tried increasing the size of the model, as well as increasing the amount of particles to fracture into.

Any thoughts?


Using defaults and GP drawing approx like yours there were no fracture issues:

Your mesh could be an issue - what if you increase thickness a bit? Does it have Subd modifier on while you try to fracture?

Cell Fracture requires a considerable thickness to be accurate, and your mesh is paper-thin.
Fortunately, the solution is laughably simple:
Scale up everything 100x, then back down the same amount after fracturing.

lol, thanks guys.
