    Thank you for the quick replies, have tried again & got better results but not 100% yet as you can see in the pics below

    This was after taking Dave R advice & moving the the high side of the profile so it is at the centre of the circle. Thanks for the alternative suggestion Dave, i shall give it a go.
    Could you tell which technique works better with a curved headed fluted pilaster

      You're getting closer. The problem with the hole is caused by SketchUp not creating tiny faces. There are a couple of fixes. First, reduce the number of segments in both the path and the arc on the profile. The other is to scale up before running Follow Me. My choice would normally be to reduce the number of segments. Unless a single flute is the object of the model and will be viewed in close up detail, you don't need very many segments anyway. You could get by with 4-6 segments on the arc and 8-12 on the circle for the path.

      As to the "curved headed fluted pilaster" I'm not quite sure what you're describing.

        Thanks Dave I will give it a go πŸ˜„ Probably not using the right description "curved headed fluted pilaster"

        below is a picture of what I mean

          Ah, I see.

          It would be much easier to insinuate those flutes the way I did in the blog post but you could draw them so they have the shape of the core box bit. Using just native tools, I would create the ends much like you are doing now and the part in the middle by creating the curved paths and running a profile over that. For that part think of the space through which the cutter would pass and draw that. Let me see if I can make you a quick example before I have to leave for work.

              Woo hoo!

              So here's a quick example of the arched flutes or whatever they are called.

              Pilaster1.png
              The set up. I'm only drawing the waste wood and not the unneeded geometry that wouldn't intersect the wood. I've got three profiles for the arcs and one for the end. We really could get away with a single arc for the Follow Me path for all three profiles but I put them all in so you could see where they'll go.

              Pilaster2.png
              After Follow Me has been run on the profiles. The end shape is copied into place near the ends. They also get copied to the opposite end and flipped along the red direction.

              Pilaster 3.png
              After the ends are moved into place and the unneeded lines deleted. These flutes are now ready to move into place on the board. After intersections are created, the skins over the flutes can be deleted.

                By the way, here's the flutes drawn as I suggested in the blog post. Much faster to draw and I think they'll pass.

                      do you have overlapping or reversed faces in your model? I am looking at a faint line right above, upper left, of the left door. It looks like the material goes a shade darker. If it's supposed to be the same material, then it means there's an issue with your modeling.

                        Nice work c-man.

                        Andy's right. why is the pilaster on the left a shade darker than the rest?
