How did you define the surface?
The cutter has exhibited wonky issues for me cutting complex volumes with complex surfaces.
I find the loop tool and loft tool are limited in their handling of complex/natural curves and defining sheets based on them.
One solution that has been robust for me is if you can build a volume incorporating your cutting surface. If you can build a solid volume the program seems to then be able to handle the cutting operation without issue (I’m guessing the volume-volume intersection testing is more robust/less path dependent).
I choose low opacity option (for visualization) only to show that the surface is lying inside the volume. The volume is actualy solid. But the sheet failed to cut the volume.
Right, I figured you’re tying to cut the solid with a sheet body.
What I am suggesting is to build a solid from that sheet body (ie a simple projection ‘vertically’).
Then once that sheet body is part of a new solid, go back and cut your original solid with the face of the ‘new’ solid.
Given the simple example you’re showing I’m assuming you’re trying to cut a complex solid with a complex surface.
My suggestion comes from trying to do blade grid blocking in Coreform. The above method allowed me to be partially successful before giving up and doing the blocking in my CAD program.
Can you reply with a “minimum working example” journal script that replicates this error? Or, if you can’t provide the journal file (i.e. can’t send an imported geometry file) could you instead provide a stripped down Cubit file that replicates the error? For example, you could delete all the volumes except for the culprit volume and surface.
Have you tried the sheet extended from surface or tool webcuts? e.g.
It is true that very complicated surfaces and/or very nasty geometry can cause even these methods to fail, which is why it would be helpful to see your specific problem, but let’s try this out first.
I have tried your suggestions but it does not work.

For my previous problem, I finally fixed it by changing the spacing between each point when I create the surface. Then, webcut sheet extended command is able to cut the volume.
Since I need larger geometry, I recreate the geometry and use the same spacing size to create the surface. But again it is failed to cut the volume. I have tried to use webcut volume 1 with sheet body 2 and webcut volume 1 with sheet extended from surface 2. But both do not work. I have tried also to smooth the surface data. But it still does not work.
The error says :
WARNING: Cutting Sheet does not intersect the original volume.
The original volume is restored.
No volumes were webcut.
