Inventor nesting

Hello,

For some reason when I use inventor nesting, all of my parts separate onto different stock sheets even though they are the same sheet size. It only happens when I auto nest straight from an assembly.

The parts will not rotate to find the best location and improve efficiency.

As you can see the 12mm rectangles wont rotate to fit in the sheet.

I feel like I have tried every function on here, am I missing something?

PS this doesn't happen when open a blank nest and import random DXF files, only when right click on an assembly and click nest parts.

This is really strange. I see on second picture there is sheet 3 and part Solid30 1. In the brackets beside part name is number 7 but there is no seven parts on that sheet.

Please check your "Remnant optimization". You can try "Minimum lenght x width".

Thanks for the response @Murat.Sözen .

I tried this and it does not work.

I just don't understand why they will not lay down or rotate to maximize the sheet efficiency.

See the other stringer actually fits quite easy in a 3m plate if it rotates, but it wont put it in the nest or even put it in another sheet because it standing up straight. If they are on their side they will all easily fit on a standard sheet.

Its like they are locked from the model and remain on the same pitch as the staircase

Any other ideas?

I've always found Inventor Nesting to be a bit finicky, but even this seems really odd.
I doubt this is the problem, but for the sake of completeness try doing a Right-Click -> Properties on one of the pieces and make sure the 'Orientation adjustments' are good, like so

Another thing worth checking too, but in your 'Process Material Library' make sure the 'Cost' of whatever material the parts are using isn't set to 0, since I've seen that cause odd behavior.

I'd also say that it's strange how it appears you have 3 sheets in there with identical nests on them, as my experience with the nesting is that in the case of identical sheets, the nesting will only show 1 of them and have a 'Sheet Quantity' to account for the others.

Dear mods, shouldn't there be a separate forum for "Autodesk Inventor Nesting" software? I must say that it was a brilliant idea to call one software "Inventor" and then create a bunch of "Inventor something" products sold separately. Really helps to know what we are talking about.
