Cura is SO poor at arranging object


Recommended Posts

Posted · Cura is SO poor at arranging object

If you have 4 simple object on a plate, Cura cannot arrange them, although there is plenty of room on the bed. But Cura can show a lot of messages that it can't arrange them, that you have to click to get rid of. DO any of the Cura developers / product owners ever use Cura and an Ultimaker? I wonder

    That’s a um3 print area. The dark grey areas are no-print areas. The switch mechanism, bed clips, or if you use dual all that + prime tower

     

    oh nvm you mean the warning msgs. Yeah, annoying thing when many pop. You can disable some auto arrange options on the preferences to remove that ones

    I know the areas. But I can easily arrange them inside those areas (as shown on the picture) but Cura can't even arrange TWO of the four inside the area. Then what is auto arrange worth, if it can only do it when it is super easy?

    This is because auto-arranging is a pretty damn hard problem for a computer. Humans are pretty good at it, which is why most people seem to think that it's easy. Getting the automatic system to the same level as a human would probably take months (if not years) of development.

     

    Cura right now uses a rather naive aproach; It tries to put the largest object in the middle first and then add the other objects. In case of a number of objects that share almost the same size, this is a pretty horrible way of doing it. But if you have a number of models with different sizes, it gets a whole lot better.

     

    The current implementation isn't the best, but it's already quite a lot better than the "old" way of doing it, which was just adding the model to the right of the existing model.

    Ah - thanks - never thought it was hard (maybe for the reason you say). So then it is up to me to find a good algorithm and get back I suppose :-)

    ... but it would be nice, though, if Cura didn't move all away from the plate and spent time on all those messages I have to close manually. It should just do its best and make the one, that are not fitting striped (like now)
