hi folks,

ive got a problem, or, better said, i am wondering, if there is another, better approach to what i am wanting to do. maybe, first you go to this link http://www.digitaltrashkids.org/poly/ and look at the pics, to figure out better, what i am talking about... there you see the cover of this sphere, where i am wanting to make something like a handle by inserting two new edges and inner-extrude those red-shaded polys there... but when i am doing so, i cant avoid tri's and that's my prob... i dont want any tris there, coz when i am subdividing the handle then a little more at the edges for later meshsmooth, i cant use the polytools in max anymore (like edgeloop and stuff..) i think, i am already started totally wrong, am i ?? i am really new to max and some help is highly welcome, so maybe somebody of you has a cool tip or approach for me... thanks and peace out...

I wouldn't cut as you're doing in the second pic. I would instead remove that inner vert, make the whole circle into one polygon, then manually create the two red lines as edges.

Several ways to do those steps, don't wanna walk through it right now. Reply if it isn't clear.

yapp, that was exactly what i needed. thanks for this... i was very confused on how to go on with that... but if i remove the vert and make the circle into one poly, won't the new poly become flat and lose it's convexness?? i will try...

think about it. as it was originally, it wasnt really convex - it was simply a single point that described its 'convex-ness'. thus it was conical.

so imagine you cut it the way the previous poster described and re-instated the convex nature by adding a few points along the new edge and pulling them out. get it?

to do this accurately, you can create a proxy spline by adding another loop of verts around the exisitng model, dupe-detaching the resultant spline, and using it as a snap to reference.

repeat with varying resolutions of loops to go from conical to convex.

Personally, I say Splines are the way to go.

Alright, I made my own real quick like in EPoly mode. Target welded the inside vert over to the side. Selected all of the inside lines and Removed them so it's one big poly. Then I got busy making horizontal cuts. Just for fun, I also tossed in an extra vertical cut. Basically what posm said, but my own flavor.

you guys rock!! thanks, i will try later this day... this is so cool, cause i'm learming very much about subDiv-modeling at the moment and this makes me really happy, yeap!!! will post this afternoon...

i finally tried to do it with the technique, stroker showed (thanks for pic) but i am still having a problem, because some of the new parts aren't sub-divedable anymore (i think..) and are causing strange artefacts after meshsmooth... please follow the link, the pictures are commented... and muchas gracias for all helping hands, that rocks! :thumbsup: this becomes a very cool lesson for me in sds! here' the link to my prob: http://www.digitaltrashkids.org/poly2/

so, the link again, it got killed by some reason: http://www.digitaltrashkids.org/poly2/

Before you start adding chamfers, select the correct edges, the ones I outlined in green...

you can assign seperate smoothing groups to the inner faces. in the meshsmooth modifier enable the seperate by smoothing groups checkbox.

chamfering the correct edges, like shown in posm's post seems harder then i thought first... pretty cool, that there are so much helping hands here! :thumbsup: i hope, i don't annoy anybody with stoopid newbee-behavoir...

ok now, i'm still in trouble here: http://www.digitaltrashkids.org/poly3/ i did as i am told, but everytime new trouble comes around... but i want to learn this stuff... !*'## just take a look... and thanks...

Dont know if this might help, but if you're about to chamfer a selection like this, select all from the beginning. Chamfering one selection, and after that some edges you forgot comes with extra work fixing the mesh.

When chamfering a single edge with all quads surrounding. four tris will appear. A good way to get rid of them is to use this technique.

Shows edges selected and chamfered.

The bottom of the insides is a bit funny because I turned those into one big poly. Had I left them quadified, it would look better. For some reason I polyfied them and left the center cut in that middle part. I'm a nut like that.

Many ways to skin a cat.

I think proteus2002 has the right idea. Smoothing groups will handle this much better. Need a group for the base of the intrusion, a different group for the 2 sides of the handle, another one for the curved sides of the intrusion, and a fourth SG for the top surfaces. No chamfers necessary. They're messy anyhow, as Egyt shows.
