Hi Gaieus, hi Jean. Interesting approaches and shows that there are many ways to create the basic dome. If I understand you correctly Gaieus, unlike Jean who creates the support beams, then builds the glass done from a follow-me mid-profile of one of the beams, you are suggesting creating the dome shape first, then extruding, or do you mean using a "follow-me" cross-section of a beam along the length of every third or fourth arc? I'm not sure if "extrude" implies push-pull, and if it does, I'm not quite sure how this would be applied to the segment radial line.
Either way, my problem is that once the basic dome exists, however it was created, I wanted to further subdivide some of the lower panes so that the surface area for any given pane doesn't get too large. I was surprised that when I used vertical rectangles to intersect the circles, then connected the intersection points, the circles still selected as one continuous ring... the radial segments didn't chop the circles into separate segments. Strangely enough, I just did a separate test and it worked fine this time. Anyway, I created a 1/8 segment in my model this way, and got the surface just fine using the sandbox from contours tool. As it was a component used 8 times, I saved a bit of size in a huge model.
It was very worthwhile to hear your different approaches to making the dome, however, a good learning experience. Thanks!
