Cage edit command that can adapt to any form automatically

Here’s a version that should work with any geometry - Breps, trimmed surfaces etc.

Here’s a fixed version that should now work also for cases when points lie exactly on faces/edges/vertices of the cage

I guess this did answer my question. I’ll have to experiment with this stuff to see for my self.

What about polysrf’s? …

I’ll have to post a challenge related to this.

I’m wondering if this could potentially be a type of solution to a problem I’ve seen inherently throughout every one of Rhino’s transformation tools.

Proposal for Expansion(Grow) tools rather than Scaling(Stretch) tools

I have a dilemma. This dilemma is almost 2 decades old now. In fact this dilemma is probably at least 6,000 yrs old. Long story short, make a truncated cone approximately 6 inches in size, with a side angle of say 45 degrees; shelled out to a wall thickness of a ratio of about 1.5% of its overall size – just guess. For example, if the overall size of this object is 6 inches, then use wall thickness of approximately 80 thousandths of an inch. Now, “scale” said object X,Y and not Z. And do t…

I think it would be sweet if Rhino could transform objects without them behaving like a loaf of bread, but rather like a shell that grows.

If I could scale an object non-uniformly, in XY and not Z, and do it in a way where wall thickness doesn’t change, and wall angle doesn’t change. Then that would be great.

Maybe some sort of advanced cage edit tool could be a step in the right direction…

I’m trying to imagine if a cage edit tool could adapt and conform to a shelled geometry to enable the user to transform it while having control over thickness and angle …
