SubD switch view between SubD and Low Poly Rhino 7 WIP

Rhino SubD
1

Is it possible to switch view between subD representation and its cage polygonal representation?

For instance I would like to model an object for a while like meshes, then switch to subD, and the switch back to lowpoly and so on.

Similar to Maya or fusion. It def makes the workflow nice.

It is not possible to do so for now?

I’m not sure, I’ve not tried 7 yet.

You’ve indicated you’d like this ability, but as of yet have not elaborated why. Perhaps the developers might benefit from that insight? I think I recall this being asked before as well, but similarly to Michael, have no v7 experience either.

In my case, and with respect to T-splines, I’m often toggling back and forth while defining form because I’ve learned to spot aspects of the box poly cage that are: useful towards the desired form; problematic and need to be cleaned up in pursuit of form; just easier to perform significant manipulation in box form.

Sometimes it’s more effective to work in box form, and other times in smooth form. Generally both, depending…AKA - toggling. I surmise I’d be hamstrung without this ability unless Rhino SubD is fundamentally different.

Hi @Petras1
I don’t think there’s a direct way (yet!?), but you can use ExtractControlPolygon on your SubD to get the underlying mesh and the use ToSubD to, well, make it SubD again. It could probably be scripted by someone more talented than I.

That and the benefit at least in Maya’s case is that the “smoothed” version is actually just a live preview, meaning the complex geometry is not actually made until you convert it to the real sub-D or smoothed polygons. This keeps the model light and you can work on complex forms without lagging the software.

Key point!
