      Partly this issue is due to follow me requirements (answer: get Profile Builder). Partly it's about working with SU arcs. True arcs would not give the problem in OP's setup.

      I wonder in regards to half arcs and quarter arcs, and even in respect to the cardinal points of circles why does SU draw them one way (Noted 12 in picture) and not the other (noted 13)? I know that segments of equal length are given for arcs. But is that really any use?

      Both arcs are from the same circle, or (for SU) represent the same half circle.

      What if every arc started with half a segment. Or an alternate (hold option key down) provided this feature? I think the arc marked 13 gives a better shape and can be more usable in drawing, if those were the issues. Would it break some rule of logic, geometry, or SU?

        Assuming that the baseline is the same length, those two arcs do not share the same radius - the 'across the flats' version is slightly larger. This is because SU always takes the radius from centre to an apex - the standard arc has lines slightly within the drawn diameter, and No.13 extends slightly beyond.
        Whether this matters probably depends on what you're modelling and what the purpose of the model is - but I think there does need to be a consistent method of determining the 'nominal' radius, for those folks who need to dimension their drawings.
        A quick way to draw the alternative would sure be handy though.

          Actually they are from the same circle, so the base lines are not the same. So I see, the way SU defines the radius this would mean arc #13 would have other problems and an arch drawn with it would not dimension properly. I keep wanting to put "circle" and "arc" in quotes. The same issue we beat to death here, but not quite, regarding finding points that would easily be defined by a true arc.

            Doesn't TIG have some plugin that draws arc in this way?

              Sorry I must miss something! 😳
              How do you draw the "13" arc for have perpendicular segments without a rotation?
              If you make a rotation, what is advantage to have odd number except kabalistic πŸ˜„

                      I did that but you showed it in more detail. Thank you.

                      Although it would be nice if SketchUP did real circles without vertices, we have to live with what it does do. It's not that difficult to set up the Follow Me path and the profile perpendicular to each other.

                        I wonder if the OP has quit?

                        Lot's of great answers here but so far silence from Anarchist86ed.

                          That's how you do it.

                          I would think the answer to the second question was obvious, the point of our conversation.

                          I will continue to wonder about other ways of doing things and try to understand what is the reasoning.

                              I wonder if you are Anarchist "86ed" (see english idom) you've been kicked out of the anarchists , or if 85 other anarchists are boss of you? πŸ˜‰
