Details
The user has a Sheet Metal part which looks like a helix with holes along the
whole length. After 360° the holes are lost in the flattened part.
Solution
Unfortunately Solid Edge often has problems with flanges/features exceeding
360°. Consequently Solid Edge loses the holes which are positioned after the
first "round" of the flange. Unfortunately Solid Edge will not allow you to
create a pattern in the flattened part, however a workaround is still
available.
The trick is to create a second part, which will be used as the flattened
model.
1. Open the part in question.
2. "Save As" -> and define a name e.g. flattened.psm (this will be the part to
be used as flattened model).
3. Unbend the model, using the edge nearest to the holes as a base.
4. Now simply move the Unbend feature to directly before the Pattern of the
holes. The Pattern should automatically find the "straight" edge instead of the
helical edge, then update the hole pattern.
This should now show a flattened model with all holes. Use this model for
further processing.
