I’m a grasshopper beginner and this is my first real question please.
Other things equal, is it possible to have Grasshopper parametricise the rounded corners of a rectangle, where those corners are
i.e. to adjust the rho or point for the conic corner to pass through
Ideally, to adjust the corners of a conic-cornered rectangular
Thanks for any suggestions.
Do you mean something like this?

Thanks for your suggestion.
Yes, something like that, although those corners are regularly rounded corners, i.e. a simple arc radius at each corner with straight lines joining them.
A conic-corner is more like the curved corners of a CRT-type TV screen.
(The value of having a conic corner, for example on the base of your file, is that it should be possible—easily or at all—to loft it with a circle at the top.)
I have done a quick search already and cannot see that Grasshopper can do conic-corners. If it cannot, I will fall back on something like the definition you’ve shown.
and cannot see that Grasshopper can do conic-corners.
edit: but this only manipulates the rho value; there is probably a way to make the interpolated version (like in rhino) but I sadly don’t know how
edit2: btw if you put in “0.707106781186548” for the weight you get a circle
Thank you so much.
You’ve given me a flying start to Grasshopper (in v.6 MacRino).
My gut instinct is to put you on ignore right now. (done!)
I’m having trouble to create conic-corner-cubes with perfect curvature.
I used “rounded rectangle - conic corners” and “rail revolve” to create a few rounded cubes in-between a sphere and a cube. The curvature of faces parallel to the revolving axis (as shown in front view) looks perfectly smooth; but the curvature of faces perpendicular to the revolving axis (as shown in top view) has sharp turns. In rendering mode, it looks slightly edged.
Is there a way to create these cubes with perfe…
@Joseph_Oster common, cut him some slack – the question (his first) was reasonable and friendly,
also the linked discussion is about constructing “conic” cubes by hand in rhino, not 2d curves in grasshopper,
