scrap flip horizontal - some symbols are wrong
I'm doing some drawing of extended elevations, and have noticed that some symbols do not respond appropriately when the scrap they are in is flipped (horizontally). Line arrow is one of them - the arrow head swaps ends in the flipped scrap - it should not. Using reverse is a workaround if the scrap is always shown flipped, but if it is flipped in some maps and not others (say, using revise) then this behaviour becomes a problem. I recall there are other anomalies that I discovered some years ago, but not sure if I posted or not. See the embedded image. One is text strings, <left> remains <left> when it is flipped, and perhaps is should instead become <right>? Another was joining of lines, which just behaved badly. There are probably other symbols, and I imagine there might be similar issues with flip vertical. However most of the time flip horizontal is just fine. Bruce
– the arrow head swaps ends in the flipped scrap – The should be an automatic decision if arrow is (mostly) horizontal - where the flip of arrow is correct - or (mostly) vertical - where it is not. m.s.
The bottom line is, features that are adjacent to each other before the transformation, should remain so after the transformation. With arrow heads there is no question that this should be so, regardless of whether there are coding gymnastics required, or whether the object or transformation is horizontal or vertical. With text string justification, it is not so clear, and ideally there should be a statement that controls whether text justification (left or right,) changes with flip transformations.
