Hello all! I need some help mirroring a piece that has a circular pattern. The part I want to mirror can be seen in the first image. I want to be able to create this exact design but on the bottom. Essentially, I want to mirror this piece using the bottom base as the mirror plane (preview of what I want can be seen in second image. Though, for some reason it throws an error " Rebuild Error: Could not attach patterned faces to the solid to form a closed body." This process works if I don't include the groove that i created with the circular pattern feature. Though, I want to mirror BOTH grooves not just one of them. How can I mirror this without throwing an error? Thank you in advance!
