newbie - rejoining multiple curving surfaces script?

Hi!

I am trying to reverse-engineer an exploded surfaces and remerge them together using a grasshopper script. I am quite new to grasshopper and was wondering if there is already an existing script out there that does this? and if not, how can i begin to make one?

Thank you in advance!

Hi nice,

I believe [Brep Join] is the component you are looking for.

Hi Nikos!

Thank you for your reply. However, the brep join commands makes it into a polysurface. I want my surface to be NURBS so I can pull up the control points and adjust the curvature. Is there another component I need to use instead?

You can try to use merge all faces to see if you can reduce the amount of faces to 1. There's no guarantee your surface can be merged into one single surface.

Hi Arend,

Is there no way to merge all the surfaces into NURBS?

There are several apps which specialized reverse-engineering design out there. You better use that kind of apps like T-spline.

i guess if you have a scan data, it might be usually obj mesh, not a poly-surf.

In the T-spline, append face command with re-topo snap makes you get a fairly close T-spline surf based on your initial scan data.

and also you can modify design while keeping the curvature continuity. and finally you can convert T-spline surf to Nurbs.

Converted Nurbs surf is usally poly-surf, but still maintaining curvature continuity.
