Rectangular Optimization bugs

[Tommy Wieler]

I'm really loving the new Rectangular Optimization feature in CN. Here are two bugs I've discovered so far.
1. Does not obey Priorities. When assigning different priority levels to different parts in the nest, the old Next X and Nest Y options both obey the assigned priority. The Rectangular mode does not.
2. Does not use Offals. Completely ignores any added sheets, and begins every nest with a new sheet.

the off falls have to be rectangular.

Priorities does not work with Rectangular, it is greyed out when Rectangular is selected. I'm guessing you were able to set priorities when in True Shape, then switched over to Rectangular and it didn't work.

Thank you both for letting us know about off falls, we will get help manual updated for next version to note they must be rectangular.

I've noticed that the rectangular nest also overrides the keep flip ops together parameter. Not sure if this was intentional or not, but I noticed that the drawers for the job I first used the rectangular nesting on, ALL the sheets were flip ops, instead of ganging them all up for the first sheets.

Correct, that option is greyed out when rectangular is on and noted in the help manual as unavailable. There are some presort options for True Shape that we can do such as keep flip ops together, but it just isn't an option for rectangular.

Thanks for clearing that up, I'm looking forward to using this new feature, and seeing where yield is truly improved, and where it just makes sense to keep using our previous settings.

I've noticed that this option also has trouble with added sheets. If there are added sheets of ANY material in the queue, then the rectangular optimization starts with the partial sheets, even if the material specified is completely different thickness. Still happening after the last CN update.

Stuart,

I see the same thing and reported to the software engineers. Thanks for letting us know.

This seems to still be a problem, even after the latest control nesting 7.09 update. Nearly got me today with a similar sized off-fall left unused in my list.

Stuart,

You are correct, this was not fixed in this past release, but is for the next. And to answer your next question, no I don't know when the next release is.

No worries, I know you guys do the Lord's work over there!
