Hi, I keep getting this message after trying to unfold a tube with a cut down it's side.
Sketch Arc length 1108.78mm chord Length 0.2mm Radius 176.5 Angle 359.94
Base Flange direction 1 = 420 sheet metal parameters T1 =2mm reverse direction radius 174.5
sheet thickness 2mm bend radius 174.5
Error Unfold1 The specified bend deduction value for the given radius and thickness is invalid. Try using a different bend deduction value, or use a different bend allowance type.
Now here is my theory, if Solidworks knows that the bend deduction value to be invalid, then it must know what the valid range is!
So could it not be helpful and show what the valid range is instead?
k factor 0.9525 works and the tube unfolds.
Is there a way to work out the bend deduction from the k factor?
