I want to bend a flat steel plate so have modelled what the part would look like flat, before being bent, and then used the Bend. Just applying one bend works great but presumably because the bent part is quite complex, the second and third bends slow GH right down. [image] Is there a better way …

Is this any better? I assumed, based on your bend curve, that the inner triangular portion wouldn’t be affected, so I removed it and added it back at the end. [Canvas at 18;09;32] STUMPY-b.gh (21.1 KB)

I don’t know what your ultimate intention is so I can’t say. In this case, the threefold symmetry made it that much easier though.If you perform it on a flat plate and then thicken, you’re confronted with the problem of offsetting everything normal to the surface, at the same distance, in which case…

Yes in this instance what you have done is a nice solution. This example made me think about what is the best way to model pressed metal components. Press tool design software often has to start with a model of the finished, pressed, component and flatten it to create the 1st press operation which …

When you’re into actual manufacturing, the problem of deformation comes into play. I don’t know much about how it’s addressed. Would those holes in your piece, after being bent, occlude whatever what was supposed to go through them? I’d be interested in how it’s approached generally im Rhino myself,…

The holes (or cut outs like a dog bone corner) are just to allow the thickness of the material to deform… If you look closely at either end of the bend axis there is a strange deformation. I was surprised that the Bend component created that but it looks remarkably like what actually happens when yo…

Well, I assumed the holes were meant for attaching, so shows you how much I know.

The BEND component works way faster with a Mesh than a surface or Brep… I tried with a flat surface but the 2nd Bend component is slow and the 3rd is like 60secs to calculate. Tried with a thickened mesh and all 3 Bends can be done live with a slider. Does anyone know why the Bend component is so…

Thanks! I like it fir this examole. For other situations maybe it’s better to bend a flat surface or mesh and thicken it after the bending?
