| Jan 1 at 18:31 | comment | added | candied_orange | @DocBrown Dan has edited. Do you require more? | |
| Jan 1 at 18:27 | comment | added | Dan Anderson | @FilipMilovanović Yes the curve can move as a rigid body. and the control line can rotate 360 degrees. | |
| Jan 1 at 18:27 | comment | added | Dan Anderson | @DocBrown it seems I don't even know the correct terminology for what I need, I tried to keep the question specific to one problem but I guess I didn't understand it well enough to make it clear enough. My apologies. | |
| Jan 1 at 18:27 | comment | added | Dan Anderson | @candied_orange ok that makes sense. | |
| Jan 1 at 18:18 | comment | added | candied_orange | @DanAnderson thanks for the edit! "the distance between C,D, and E could stretch but I would like to keep their distances to A, and B roughly similar" I don't have a proof handy but I believe so long as the distance from A to B is the same then the C,D, and E distances won't stretch at all. Only rotate. | |

| Jan 1 at 17:56 | comment | added | candied_orange | @DocBrown you can find my response here. If you still think that OP meant something different please provide a detailed explanation of why so the OP knows what needs fixing. I can't help Dan the way you can because I don't see the confusion you see. | |

| Jan 1 at 16:25 | comment | added | Doc Brown | @candied_orange: I am convinced the OP meant something different than what your answer addresses, and I see your answer just as a wild, speculative guess - which is most probably wrong. I vote to close this question because it is so vague I suspect the OP does not really know what they really want, and asks us to do the requirement analysis for them. But maybe I am wrong, so I am happy to revoke my close vote when we get a question where we do not have to guess what was meant. | |
| Jan 1 at 15:54 | comment | added | candied_orange | I’d rather get clarity on “It is alright if the curved line distorts it's shape”. | |
| Jan 1 at 10:37 | comment | added | Ewan | beizeir curve? make point A be the tip of the curve | |

| Jan 1 at 5:54 | comment | added | Filip Milovanović | Is it OK if the curve moves as a sort of a rigid body attached to the line, or are there constraints that would prevent that? E.g., if you rotate the control line 180 degrees, do the endpoints of the curve rotate as well (flipping their left vs right relative orientation), or should they stay fixed, or at least close, to their original locations? Is the control line allowed to rotate arbitrarily (including extreme angles such as 180 deg), or are there limits? | |

| Jan 1 at 0:21 | comment | added | Dan Anderson | It's a user drawn line it could have more curves or be more straight. | |
| Jan 1 at 0:19 | comment | added | Christophe | It's not a translation but a combination of translation and rotation. It seems that you draw a parabola symmetric to the line, and with a focal that is at the intersection with the line. How do you currently compute the points on the black curve ? | |
