ok I have a piece of a model seen here, and I basically want to add another oval division inside the same oval shape. I don't want to just cut because it wouldn't be perfect. So how should I do it? I tried to shift-rescale the outer oval but I couldnt get it to work

select an edge
click ring
click connect

i'm sure there's a million ways to do this but the first that comes to mind is select the outer ring in editable poly-border, create the shape, extrude and boolean-subtract to the original, convert to editable-poly and rebuild the hole and cut your polies to match...

...because the edges all share the centre vertex.

Just select all the edges that radiate from the centre and then click connect.

that would also work dizzl8r... but it's a very "roundabout" way of doing it.

Not sure if this will work but give it a try...

Vertex mode. Select middle vertex and chamfer.

Duno if it makes any difference using mesh or poly


OR

Select outer edges and chamfer

I would simply select all the polys, (or 'tris' I think is the correct name) extrude them up an incredibly small ammount, and scale that in. That will produce that extra ring of edges that you want, that's if Im understanding the question.

ohhhhh, I now read thats the first thing you tried. Well instead if 'shift/move' use the extrude function in editable poly. :)

Any of the methods work... select all edges and connect, sellect all polys and inset or any of the complicated ways of doing this simple thing... :)

Try them all out... :)

And another one:
make it a editable poly, select the inner Polys and use "Inset" from the "edit Polygon section.

hope that helps

thanks for the replies guys (no rhyme intended for those offeneded......omg)

a couple things I forgot to mention:

1. it is an editable poly
2. yes, there is a single vertex in the center
3. its not a flat shape, there is a small depth to it, but you can't see it in the picture, but if you look at the bounding box you can see what i mean.

Spindle - that would not work, I do not want to increase the actual dimensions of the shape in any way.

Ok, you know when you create a cylinder primitive how you can inscrease the divisions horizontally, vertically, and on top? Well I want to increase the "top" division here just once. Its easy to do with a primitive, but I'm trying to figure out how to do it manually here.

I will try out your suggestions later today, and thanks again

dude, with all due respect (not trying to be rude)...(and not trying to rhyme either):
we have provided you with more than one way to do what you are trying to do. It appears to me that you need to go back to the manual and learn a little more about the poly tools max has to offer. I recomend working through the tutorials that ship with max and don't try to just start modeling as you will end up frustrating yourself.

actually I've been modeling with max for a long time and have completed 90% of the tutorials, (and all of the modeling ones). And I searched the manual a good deal and couldn't find the answer. Also, the way you suggested, by clicking ring and connect wont work because that won't do what I'm trying to do.

how about the inset method? or evan the round-about boolean method that dizzl8r suggested. if neither of these will work then please try to explain a little more what you trying to do becaue I can't say that I understand. maybe take another screen shot a slightly diffrent angle and draw what you are trying to accomplish on the pic.

Sorry, I wasn't very clear, I know. When I get home later today, I will try out all the different suggestions to see what works and then take a ss and post it later.

EDIT:

this is what I'm going for:
(excuse my bad drawing, assume the inner oval is perfect =)

I still think Ring>Connect will work. If the size/postion is not correct you could select one of the edges of the new division > click loop > Change your restraints to Edge > and then scale/move the new edge loop to its correct size/location. At least this is the method I would use.

ok... is this what you want?

I made this in under 20 seconds... create a cylinder > convert to editable poly > delete all but top face > inset: 1 > collapse selected faces > select radial edges > connect > select all faces > scale to create oval shape > done.

Now, this takes no time at all... and is a very basic operation. You can easily scale the inner oval by using "constraint to edge" and using the scale tool.

Best of luck

Spindle - that would not work, I do not want to increase the actual dimensions of the shape in any way.
I tend to think it would, when I said to 'extrude by an incredibly small ammount' I assumed you would realise that you can just select all those vertices and scale them in, or select the faces and push 'make planar'. This of course may alter the position a MINUTE amount, but if you are worried about complete accuracy just use the align tool.
Maybe some of the other methods may be more suited, but I think its a bit blunt to say "that would not work".
Hope you get it sorted. :)

Edit: ok here is an even simpler method with no special tools: Delete faces, select the edges, puch shift and scale them in (half way), push shift and scale the edges that are now selected in again this time to the centre, weld the remaining vertices. Problem solved, and this time with complete acuracy :)

well ok, I'm not going for absolute accuracy, its just when you said extrude, I said that it wouldnt work because i was thinking that it wouldnt be flat but it would seem that i completely forgot the existence of the "make planar" button while I replied. =)
