I’m receiving weird results when subdividing particular objects using the 3D Subdivision tool.
Example 1: I just had an object turn into a cube while I was attempting to slice it into pieces via 3D Subdivision
Example 2: I start subdividing the object and it vanishes. I have done a lot of subdivision on the objects in this file and this is the only one that vanishes.
The selected object is probably not a valid closed shell. For such object it's recommended to modify the default subdivision options.
Try changing the settings in Options>3D View>3D Subdivision:
- Change the Toolkit to Advanced
- Change Triangulation type to Always triangulate
- Disable Try sewing to solid
