Cannot Unbend or Create Flat Pattern

[CJK_Acuity]

Help please! This model will not flat pattern or unbend. All radii seem to be constant and the part is fairly basic. Can anyone see what the problem is? I'm in creo elements/pro 5.0

The problem is in your first two Bend features. The radius cuts slightly into the main bottom surface. You can either adjust the distance or create a Rip inside the Bend features.

I'm on Creo Parametric 2.0 so can only provide screenshot from this release. Note Form features are suppressed due to missing reference models.

Thank you much!

Your part is actually set to the default relative accuracy of .0012. Changing this to absolute at .0005 will also resolve your model.

Have a look at this discussion: http://communities.ptc.com/message/260507#260507

Default sheetmetal part template values are absolute .0005 for inch and 0.0125 for metric.

Remember that you have to enable absolute accuracy in config options or config.pro

enable_absolute_accuracy yes

You can do this option in session.
