Ok im running 4.94 and its been out for awhile and maybe its just me but when a back in a unit i've made is say 1475mm wide and 1210mm high well it cant nest it. even if it 1000mm high it cant nest it. The sheet stock size is set to 1220mm wide and 2440mm in length. It is almost like RN thinks its a grain back which it isnt. I do hope this is happening to other people and not just me! It comes up with \" warning cant nest the following\". This never used to happen and this has caused alot of problems for me with parts missing and when im doing a 100 sheet nest its hard to know if a part is missing. And also when i nested this big job the \"warning can nest this\" only came up for a second and had no info of what it couldnt nest.
It may be worth a quick check of your \"part rotation step angle\" setting in Control Nesting. If set to 0 or 180 CN will not attempt to rotate the part 90 degrees to fit the sheet.
