Reference between fold and unfold model. SheetMetal

[mirkomaga]

hi, I need to derive the transformation matrix between model and sheet metal. I need to associate the folding edge of the flat model with the edge of the model, what can I do?

There is no single transformation matrix between folded model and flatpattern.

You can try to use this two methods FlatPattern.GetFlatPatternEntity and FlatPattern.GetSheetMetalEntity

or you can try to use planar sketch and set CopyToFlatpattern to true. Later on you can get two transformation matrices from this two sketches and calculate your own transformation between folded model and flatpattern for specific sketch (planar face).
