Not reducing sheets size when deducting

Thanks. We currently edit it in the Optinest editor, we also flip the piece in both the X and Y directions so we can still keep nesting to the bottom left corner. It would be a great aditional that would save time and not waste an of the material by triming it down.

Hi all,

I’ve sent this request to the developer team and they are looking into it.

However for the time being they have a lot on their plate and it’ll probably take a bit of time to get something added.

For the time being, either you run a tool around the offcut to trim it to the Optinest size or edit the offcut in CAD or the Optinest editor to fit the real size.

In a lot of cases editing can be useful to trim the offcuts to manageable shapes.

Here’s quick video using the Optinest editor to adjust the size of the an off cut:…..ab6c00391b

Hi Ness

Yes I will second this as we get the same issue.

For two sided the offcut needs to be totally accurate and the allowance on optinest of 5mm (same as kerfworks) means the offcut is reduced by 10mm and this then needs to be manually adjusted.

Thanks for making this remark.

This is something that we haven’t looked into yet. I’ll ask the development team if they can do something.

When deducting a not complete sheet of nested items to save the offcut. The offcut size has got all of the area where the items are place removed but it also removes a section around the original perimeter of the sheet.

We use sheets that are 2440 x 1220 in optinest with a panel trim cut of 5mm. If we nest on a single piece and save the offcut the overal size of the offcut is now 2430×1210. If we do it again it reduces down to 2420×1200 etc etc. We are finding ourselves manually then going in to edit the DXFs back to the full original size of the sheet. 

I understand that the celarance is also taken off for the tool diameter on the nest, but if the overal perimeter is not touched by the tool I cant see a way to not get the deducted offcut to reduce in overall size.

Is this an option somewhere?
