outline and extrude inner

[Inktvlek]

I'm not sure about the 'extrude inner', isn't that just the offset?

As for outline, I would move (in this case) the pivot to the center (as you have done in the picture) and then just duplicate with scale... Is there a big difference between duplicating a feature with options like scale, move, rotate etc?

[ambient-whisper]

some apps call that "inset"

you can get a similar result by extruding and then moving/scaling the points along their normals. not sure how its done in maya. but thats how it works in other apps

create outline : offset curve

extrude inner : the regular extrude tool but you just click on any scale little cube (x, y or z whatever) then tou tweak the center cube (light blue) of the manipulator.

It does quite the same as in c4d except that the manipulator tool doesn't center itself automaticaly, you will have to clic on the little blue circle before.

Hi Okno,

As far as I can tell, Maya does not contain these functions out of the box, yet I'm sure there are scripts that will reproduce the results.

I am not able to recreate the extrude inner without manual tweaking.

For the outline, you can use duplicate curve on surface to get copies of polygon edges. but this requires manual selection of the edges, then manual curve attach to create a single curve. For anything complex it is easier to set a point snap and just draw a new curve along the edge you want.

I doubt this is much help, except to cornfirm your observations.

If anyone has more insight please say so. But as was said in the original post... extrude inner is not the same as extrude + scale, so don't keep going down that road.

Inset

Hmmm, I think this feature come out of the box as standard feature on edit polygon>extrude face. It just maya called it Offset instead of inset.

Scaling might not do the job, because offset has different behaviour than scaling. Just make sure you have your face keep together on

:)

[Electrofirma]

Yes!

Thanx Misterdi!

Okno, to control this offset(inset), make sure that history is on, and select the word 'offset' in the channel box and middle button drag in the viewport.

Thanks again Misterdi. It is neat learning about this program, especially when it is powerful little features like that.

if you plan on lofting, you probably want to set your subdivison density to 1.

Ah, just like I said! Thanks for clearing this up! (I was not completely sure about it since I never used C4D)

I don't believe I didn't know about that! :rolleyes: Cool

It appears to work best - on polys anyway - if the shape you're offsetting has no internal edges. Then you achieve a uniform offset. If that makes sense.

[misterdi]

Even if you have internal edges, it should work. Just make sure you have keep face together on

:)

Hmmm.. I might be missing something here, but these are the results that I get using offset with and without internal edges and keeps faces together is definitely on:

Without internal edges

[Electrofirma]

Yeah, that's messed up! I've got no explaination or cure.

use my fcOne script to unify the faces into one before you do the op, offset, then, if you want to reinstate the same faces as before, do some triangulation and quadrangulating (or combos there of, depending on what you start with).

/*

fcOne
--------
makes selected blocks of faces into a single.

Usage:
---------
- select faces, call script, fcOne.

- if it abbuts a border edge, you'll get an
error, but it is no harm.

*/

global proc fcOne()
{
select -r (`filterExpand -sm 34`);
if (!size(`ls -sl`)) error "select face blocks to turn into one";
else {
$edgs = `polyListComponentConversion -ff -te`;
$oln = `polyListComponentConversion -te -border`;
select -r $edgs; select -tgl $oln; delete;
}
}



.. use bonus games edge crv extractn script to extract single, connected, crv from contiguous edges.
