Here's a look what it looks like with tabs and with them chopped off. Not sure how people fell about butchering lego but the piece is useless with them  on to me. It's an odd shape as well, think it's 11 studs across which gives it that slight overhang. It wouldn't work with the digital moc as I have an office in the dome so I only need half a dome so you can gain access to it.
