Varian....I am copying and then pasting. going to another window to reselect it..and then moving it....but when I do, I can no longer see the original object....or the objects underneath it....eg. I made a block... made a colum to sit on the block..and I lost the block. I lifted the colum above the block height and dropped it. It landed on the block. I go to move it..and the block is no longer visible to enable positioning of the block. I copy the column...paste it, reselect it...move it..and the block and the original column are missing. Yet the colummns and the blocks are there in the camera view...just not in the viewport Im using.....totally weird :/
