#Union not unioning

I'm trying to Union two objects without success. I made the first object from a 12x12x1 grid. After some manipulation of the grid I hacked off the faces that made up the depth of 1, so it was just a 12×12 object with no depth. I bent it so it made a semicircle, then mirrored a copy of it. Then I tried to Boolean/Union them together. What I got was an intersection! It seems that Union doesn't like one-sided objects. I've run into this problem before. Any ideas on how to get around it without changing the geometry? I did a Create/Object/Attach but this leaves a seam, even if I do smoothing. Lerv, Michele

As you said, you can't use booleans with one-sided objects. You can try it with a two-sided grid, and then after the union, delete the other side. Or you could try selecting intersection or subtraction, and see if that gives you the intersection you want. – G
