How do I make a fluted column like the one in the picture

I finally got it. But it wasn’t as I would have expected. I was working with the columns in actual size, 3" in diameter, and was using a flute that was 1/4" across. I couldn’t get the flutes to lathe with the ends rounded. And then when I attempted to embed them into the column, intersected their faces and attempted to remove the outer half, the whole flute disappear and all that was left was the outline on the column’s surface. I tried this multiple times. Finally I tried to do a sample flute lathe, Follow-me operation, but made the shapes much larger. It worked. It created a properly shaped flute-shaped cylinder. So I decided to scale the entire column up 300%, went through all the steps again, and it worked! The flutes behaved properly and were perfectly shaped into the column. I then reduced the image after making the whole thing a component, by .33% and everything stayed put. I know I’ve read somewhere that SU does have trouble working in smaller thresholds. I suppose this was an example of that. Anyone have any opinion on the subject?

Which leads me to another problem/challenge. When I attempted to import this model into the kitchen model, I ran into a stability problem that was nerve wracking. The object would appear on the floor with the “Move” icon on the screen. The twirling rainbow would start turning and the object would jump to another location, then another whirling rainbow, and this went on and on. After a number of tries, shutting down all other open aps, and rebooting, I finally got it to stand still, so I could actually position it where I wanted it. I think my MacBook Pro w/ El Capitan OS X 10.11.4, 16 GB ram, 500 GB SS Drive, Intel Core 4 I7 2.5 GHz processor and 2 GB ram was meeting its limit and I still have a lot of kitchen to “build”. I’m attaching the whole file for your edification.

I just tried uploading the file and it says it’s too big. Perhaps, that’s why things are behaving so badly. What are some techniques for limiting the number of elements in the drawing so the system can hand it?
