<p>Very nice. Seems to work well on breps with planar surfaces but not on curved surfaces like the top of the "?". Good work on handling the data trees of surfaces, curves and points.</p>

Joseph I wasn't theorizing - my disclaimer was that I could have misunderstood, therefore I did ask if by uniform he meant proportional. That's all. I do get it now upon discussing it in detail. Thanks for disproving what I wasn't asserting hehe<br />

Cheers

<p>Here is a go at the tilted rectangular box at the bottom of the "?". The diagonal lines are an indication of failure. Four of the six faces work but two are twisted garbage. This is the kind of typical Grasshopper nonsense that will drive you up the wall! And it won't work with the curved top part of the "?" anyway. I give up, this is impossible. :)…</p>

<p>Seriously, this reminds me of solutions I've seen somewhere for thickening a complex bottle shape, but that didn't involve miter joints between adjacent surfaces. Nope, impossible. <em>(kidding...

<p>I see,</p>
<p>Your original post <em>does not</em> mention you need a controlled offset, it only implies you want clean intersections - thus it becomes tough to understand what you're after. Still, in the file I sent all faces are planar, other wise the cap component would not work :)</p>
<p>Alternatively, you can <em>still</em> measure the distance (face to face) and display it graphically, even while you're scaling via volume. That gives you a pseudo controlled offset.</p>

<p>Once again, I might be misunderstanding <em>which offset</em> you want to control: the planar offset of each mesh face <strong>OR</strong> the offset of the polyhedron towards the inside.</p>

<p>This is really funny. You're taking the same steps that I took. But there are conditions to take in count before.</p>
<p></p>
<p>Because it has to be manufactured, we need to control the offset distance. Using an scale doesn't make the resultant breps uniform. That's why I was telling to Joseph before about the normals of the vertex and the cross product.</p>
