Maya Inset - Is it possible in 2016(7)?

gestoryscht

Hi, it's me - again.
This time a question about the general modeling toolkit of Maya.
I want to inset a whole pair of polygons, like in Blender Inset, Modo Bevel and Max Inset, but I can find any solution. I've searched now and the only thing I can find, are posts from 2010 and some rant about it.


I want to achieve this

The extrude offset method produces double polygons
How?

Stavaas

If you use the translate tool you get those weird edges, but if you use the Offset in the pop-up menu your edges should stay nice and straight

Okay, this is really weird. Now it works.
I restarted my computer and Maya, selected the faces and now it works like a charm.

Before Maya produces artefacts - because of overlapping polys. Now everything is right ^^
Anyway - thanks for your help!

Stavaas

No problem, Maya is a bit wonky sometimes haha

Okay, back with the same problem.
To be honest - I dont get it ~

1. Select faces and run Extrude. 
2. Make Offset exactly as you want. Once done don't deselect anything and...
3.  ...grow selection only once - Shift + >
4. Invert selection - Select > Inverse 
5. Press "Delete" key.

PS. Once you have it deleted and if you don't delete history you can go to channel box and select polyExtrudeFace you created for it. 
Now you should be able to adjust Offset again without that additional geo getting in the way.

Well, actually this sound very sophisticated for a task like this and in the case there are more loose polygons, the method isn't very practical, because the "islands" are get deleted, too.

Is this really maya does the job?

Klaudio2U

If there are more "islands" of faces around and those islands are all combined under one object with the one you doing extrude - this "bug" will not happen. 
This only happens when doing extrude on mesh/object that is not closed or water-tight (i.e. cube) and has no "islands". 

Workaround i mentioned is actually fine, for me at least, and it's literally Extrude (Offset) > Grow selection (Shift+>) > Invert selection (Press and Hold Shift again and drag marquee selection square across all components) > Delete....takes 1 sec do do it all.

Okay, to sum it up - it isn't really possible in the newest Maya version - just with a workaround and for me it is a bug.
What is the logic behind this?



For the future I will use your workaround, but I hope Autodesk will fix it some time...
Anyway. Thanks for your help!

Klaudio2U

Ah yes, unfortunately the only thing is to manually delete that additional faces.
I also wish this doesn't happen by default and actually i sugested fix for this issue exactly, together with some other extrude stuff, quite a while ago on Maya beta forum but...

if you extrude a plane (all faces including borderedges) maya tries to create a volume...
if you extrude first downwards and do the inset in a second step it will work...

gestoryscht

The thing with the volume sounds logical and I figured it out, too - but this can't be the real reason for this problem. Please take a look on my last screenshot comparison. On the left hand was the exact same setup like on the right side. The only difference was, I mirrored the non-manifold element and et voilà the inset works fine.

i found a workaround recently for those transitioning into maya.

Panupat

That's a nice workaround onionhead.

Anyone knows if this has been fixed in Maya 2019?

Hi, I figured I would just comment on this thread since its the same issue I just noticed. Surely this isn't still a problem in 2021? What am I missing?

Maya2022 does have some improvements for inset.

What improvement?

Maya 2022 still extrudes and cant just Inset.

Its doing what i would expect. Its an extrude.
