Radiate command - Radial symmetry in SubD >>New feature<<

We (by we I mean the devs) are working hard on radial symmetry, Give the Radiate command a try and let us know your thoughts. (7.5 and above)


great that this is in the works :slight_smile: The interface for defining is weird though. Please have another look how it was done in T-Splines.
Also, I think you are aware of this, but there is no way to see which geometry is the ‘parent’ part and here it is even more important that the changes can be made to any part of the symmetrical shape. Right now moves work, but extrusions do not (on ‘child’ parts).
Would be nice if axial and radial symmetry can be applied at the same time.


Agreed on all points, thanks for this-
It’s an early work in progress for sure, look for further development and refinement based on all the comments that come through on this thread.


Radiate not work here, RH_SR5 2021-3-23
Rhino crashes or nothing happens…

+1 to all the points @Gijs listed.
Other then that is works already quite well.

Bridge also works in Radiate mode… only that it will let you go though all the bridge steps only to undo it all on Enter if one missed the parent Radiate.

The Bridge creates a self-intersecting geometry at the Radiate axis, which can be the intended result, but an option to auto join at the axis would perhaps be very nice to have. [eventually]
Is there a limit to the number of segments allowed?

thanks a lot


Perhaps Try 7.6.21110.13002, 2021-04-20


yes, we def need a visual on parent/child-

agree on auto join on self intersecting stuff

I confirm It works on 7.6, didn’t work on 7.5.
my wish is to have an interactive way to update the number of clones through a parameter that I can edit. also if it is possible to adjust the angle.
+1 for the auto joining of clones
+1 for Parent/Child visualization

for this, you’d need to run it through grasshopper-

Can’t wait for the Reflect + Radiate Grasshopper components with auto joining of generated clones

Thanks for adding the visual shade cue the the command.

I have a question regarding the Yellow 90 degree lines that comes up when the Pick point dialogue appears…

  1. which part of these yellow lines determine the pick point?

  2. it is confusing as these yellow lines behaves as one would expect in a Perspective view, while the Top view is active [and Max]

  3. I feel it would be helpful if the Radiate dialogue [ suggest not force] recommended number of devisions in accordance with the selected SubD object ! For example : here is have 16 devisions in this Torus, so a Radiate devision of 16 / 8 / 4 … will work without breaking the subD object, but other devisions will.

thanks a lot

osnaps are super helpful when placing the locators.

I agree some intelligence in the segment numbers would be helpful, I’ll write that up-


Yes for sure, Only that the logic of these locators is not immediately clear. Of these 2 yellow lines, which one should point to the location? or is it meant to define the general area between the 2 lines…? And why are they behaving perspective like, in an orthogonal view?

Thanks a lot

the space between the lines is the slice you will define for the parent object-

Thanks a lot, yes now it is clear.

It’s the use of words [pick a point] in the dialogue, that created confusion. Perhaps " define a parent segment/s " would be better use of words?

with best regards

Radiate command documentation is here: Reflect
Its little movie describes it as a command which blends several SubDs into one SubD. In reality there is no blending and not much difference between the Radiate command and ArrayPolar + History.

The same documentation file describes RadiateFind command. This command does not exist.

what service release are you running? You may be an update or two behind this command documentation-

both commands showing here in
Version 7 SR9
(7.9.21189.11001, 2021-07-08)

Rhino 7.7. When I check the updates in Rhino 7, it says “This Rhino is up-to-date.”

it’s coming to you soon!

The Radiate command still does not work in Rhino 7.10 :tired_face:
