Help with a weird problem in Maya

#1

Hey, I’m realitivly new to Maya and I’m having some issues I haven’t experienced before.
I have this model of a ring that I have triangulated previously for printing purposes. However I’ve had some issue with the thickness of the actual ring and wish to change that, so normally I’d just extrude the inside or something to add thickness to it, but to do this easily I’d need to change the mesh back to quads (which is something I have done before with this same model). However it’s not changing back to quads this time and I’m not sure what else to do other than sit here for like 3 hours selecting all the faces individually.
Anyone able to help out with other options or why it might not be going back to quads?

As a last resort I might have to open a previous version from before first triangulating it, but since then I have made some changes I’d have to redo, so if I can avoid that, that’d be brilliant.

You can select the inner edge loops. Right-click on your model and choose Edges, to go into Edge Selection mode.
Double-left-clicking on one of the inner loops edges. And then shift double-left-click on another of these inner edge loops.

Then you can do: Select > Convert selection > To Faces.

And then maybe use the- Shift with period -keys to grow your selection.

I hope this can save you time in the future : )

Try turning off the “keep…” Attributes in the options of the quadrangulate command.
