I used bevel on onr of my cubes. Then I use Boolean union to join this cubes together with other BASIC solids (the ones created under Blender mesh function and I did not manually edit the vertices or faces etc). This works fine. Then when I try to use the resultant object in other boolean operations, Blender complains:
Both Meshes must be a closed mesh
and I confirm that the resultant object from the boolean operation above is the culprit (by attempting to union it with a primitive UV sphere directly from the add mesh function.
Now, how can I fix this problem to make the object resultant from that boolean operation become a “closed mesh” again so that I can use it in other boolean operations?
I would appreciate any prompt help because my assignment is due tomorrow.
