This is a reply to the thread where Glenn McCarron is demonstrating his project to make the Eagle Bowl. This reply is in response to how SketchUp can be used to visualize the inside of a feature ring after turning and also to know how big the wall profile will be at the feature ring.
Please let me know if you have any questions. Here is a link to his thread:

WOW, WOW, WOW! This is amazing Lloyd. Ive followed along and understood most of it. I have to reboot to the Dark side (PC) to grab the image to import and then I can try painting and copying.

Lloyd I finally managed to replicate exactly what you have done. The only difference and I suspect it is in the preferences is that I was 1/16 smaller in all diameters. Why do you mark the segment at 15/16 and start your mitre from there vs just cutting a complete mitre. My only guess would be to increase the diameter slightly??

Is there any way in sketchup to make your piece solid so that you could see the result of a cut through a given lamination?

I am really eager to see other of your tutorials. This has been an amazing inspiration to me. Thank you for sharing.

Glenn,
Before I start a new project, I make a quick check to make sure that my saw blades are perpendicular to the work surface and that my fences are correct. This way, I'm confident that all of the opposing faces of my segments are parallel which allows me to work faster. For example, when cutting angles on feature ring segments, I set a stop of my fence so that I can cut the first angle and then simply flip it end-to-end and place the other end against the same stop and make the second cut. By leaving a 1/16" reveal before the angle starts, I can always perform this flip. If I cut to the end of the segment and overshoot this by as little as 1/32", I have to re-position the stop and symmetry is compromised.

SketchUp has added tools and capabilities to make models appear to be more solid but I have not yet experimented with this and I have my doubts whether it work as intended. It's a huge departure from the notion that all objects are made of nothing more than surfaces and lines. I hope I'm pleasantly surprised, though.

I do have some additional SketchUp videos - most of which were made some time ago, but since the tools haven't changed much, they are still useful and you'll like seeing some of the tricks I've learned. Here's the link:
