I have two parts that I arranged using only the default studio tools. My grid is set to 1/5th (0.2) of a stud, both wedges are sized (1.4,1.4,1.4), and I moved them around using purely the default dragger and R/T. I cannot union the two for the life of me and they give me a -9 error and move the the origin after the union fails. If I union them after they teleport to the origin the operation still fails. If I copy and paste them into a new place and attempt to union them, they fail again. This is making me tear my hair out because I’d never something this simple could throw an error.
