SheepMetal additional transformation data

Hello community, @felix.brunold ,

Is there currently a way to get additional transformation data out of the unrolling process?

Particularly interested in transforming additional curves (e.g. product tags) from the 3D brep geometry to the unrolled flat pattern geometry. Would be a start to be able to get plane-to-plane transform data for each face and then one could easily map things from the 3D object to the 2D unrolled sheet.

Thank you!

@Dragos_Naicu currently this feature is not available yet since I’m currently working on a new unroller that should be faster. With that new unroller architecture, the idea is to also allow attaching further data to the unroller.

As a quick fix, I could expose the transforms just probably with curves going over bends. I’m not sure how well that would work since the unfolded surface is shorter, and for the quick fix, I most likely would not adjust for that since I’d rather spend that time on the new unroller. But if that’s already what you need for planar stuff, I could expose that. What do you think?

@felix.brunold thanks for responding. If you can expose that, would be nice to try.
But I wouldn’t want to divert you from your unroller path.

Really appreciate it. Thanks!

@Dragos_Naicu I just made a beta release with the new unroller. (need prerelease toggle check)

With the unroller map, you can now add points or curves, and they get properly projected to 2D with k-factor correction, and the unroller should be quite a bit faster. Currently I’m tracking only objects that are directly on the face and on the right side of the sheet that gets unrolled.

Thanks @felix.brunold !!

I will test it as soon as I can. Will let you know of any issues.
