Summary | 0000743: Conflicting auto constraints | ||||
Description | Hi, (at first I thought) this is not a big deal, but I still wanted to report it. there is ability for auto constraints to create conflicts. Take a look at the picture. you see that right and left side have length constraints that are almost the same, and when you add additional line, it adds auto constraints coincident and horizontal. However, this causes conflicting constraints to appear. At first I thought this is not a big deal, but after thinking about this little deeper, I think we recently had occasions when people would have conflicting constraints that were added automatically, and they had no idea why - I think they were auto added as orizontal, vertical... This can be a problem when you have really big sketch. usually you draw it and then constraint it. If you, after that, go modifying it by adding new lines, sometimes conflicting auto constraint can appear, and you can get confused in the big forest of constraints which one is problematic. Usually there are two auto constraints added - coincident or point-on-geometry is first, and horizontal or vertical is second. Suggestion would be not to add horizontal/vertical constraint if it will cause conflict. Regards, Petar | ||||

Mhh, normally (at least me) you do first the sketching shape (closed loop) and then adding length and angle constraints. If you start with length constraints, I think you have to switch off auto constraints. Generally its always possible to shoot itself in the food with the constraints. And since logari did a very good job explaning stuff like that in its solver messages I don't see a point in that bug!? |
|
Apologies, my trackpad is a little too sensitive and I assigned this ticket ot myself. Corrected. My question is about the fate of this ticket, can anyone weigh in? |
|
Punting this to @logari81 to decide the fate of it. (hope that's ok?) |

There is no image anymore. I do not know what to check... |

Cannot be reproduced with the information left. |
