Rhino 7- Using QuadRemesh to Reverse Engineer a Scan

Learn how to use the Quad Remesh tool in Rhino to easily reverse engineer a scan of a last and output a clean NURBS surface.

[I.AM.]

I need to acknowledge that Rhino-7 release outweighs all the negatives of 2020. An amazing tool I was glad to purchase and start using!

WOW. I just learned Rhino last week, and I was able to pull a clean Sub D model off of foot last .stl I got off of Etsy. This video was essential for me. Thank you so much! One thing to add, I ran quad remesh twice and that seemed to help as well.

converting a mesh to subd was shocking. But this all depends on intent. When you start manipulating the vertices and you don't have any deviation analysis, well you can't call this a reverse engineering product. But Rhino is working on it and that's awesome

Thanks a lot Kyle for this workflow. reduces the anxiety to fully get a grip on my SubD-pipeline. Will still switch between Modo and Rhino to develop the designs. this one is massive.

you're a great teacher...thanks for sharing!

wow great tutorial i am really impressed!

Great tutorial!
Thanks for sharing with us.

Very nice! Now all you folks need is to employ XYZ Transformation & Pivot Point nodes with Hierarchical Modeling, and you will have a fairly complete concept design tool that can prepare production data for complex products. Why not add some deformation tools while at it? I would love for Rhino to eventually become Maya killer(I have been using both for the last 20+ years because I have always needed both). For freelancers and small studios, the combination of Rhino 7(and Grasshopper) + Blender + Fusion 360 looks like it will be the ideal combination for the next few years. Please keep up the great work!

I used quad remesh on my shoe last, and 3d printed the object and it came out much smaller than the original 3d scan.
I wish you would show how to use quadremesh on a shoe last and get closer Dimensions to the original 3D scan of the last.

All the SubD point relaxation / edge loop re-fitting could of course be done a lot easier, faster and with greater precision in polygonal modeling software - the unsubdivided SubD state being exported into a mesh and edited with a Shinkwrap modifier on top of the original unorganised shoe mesh. The presented UVN method of rearranging the SubD points might lead to more arbitrary results as opposed to vertex editing with a Shrinkwrap.

The re-fitted base mesh could be then brought back into Rhino's SubD state, then converted into NURBS surface set, etc.

Hey Kyle, does the sub d in Rhino 7 have a snap to mesh feature? Thinking of dragging control points and having them drag along the mesh "surface."

Easy to do it with half, but doing it with the full last is a headache.

Rhino 7 is Beta now. Will they release soon?

rhino is a little like 3ds max now - same old software (with archaic gui) with couple improvments - bam! - new version. No wonders since competition is weak.
