MAX5: Help with boolean/shapemerge problem

[jadedchron]

sift thru the sticky subd thread. if i remember right they talked about this

[gaggle]

Yeah stuff in the Sub-D thread indeed.

One thing though, Rhino is a NURBs modeling tool I do so believe, so trying to use the same workapproch in MAX isn't guaranteed to work as nicely.

Your screenshots looks to be in the right direction? Specifically making the little ring that sticks out from the surface around the holes, could be as simple as selecting a ring-loop, making a spline out of it, and setting that spline to renderable?

I died in the Sub-D thread. I'm waiting for the simplified version to surface...

But for now, can someone help me on this idea?

I know I could just boolean the shape out with a solid object, but that doesn't seem like the right way to do it, and it doesn't help me with getting the ring around the edge.

I did get the shapes on the cylinder as you see. But I can't select the poly's between the edges it created, I don't know why. I also shapemerged the outline on there, but it went crazy when I did some extruding/beveling.

It doesn't look like a hard thing to do, but i can't figure it out. Help me, [insert your name here], you're my only help.

Befuddled,
Sledge

Howdy !

Like Gaggle mentioned, Rhino is a full Nurbs modeler, and as such does this kind of things a little better than Max does, but we're speaking of Nurbs.

Now if you want to do this, say, with EditPoly's, you still might want to look up that sticky thread, or look up any good Subd modeling tutorial.

You could simply make your polys a rounded shape by adding a couple edges, chamfer that a little, extrude the middle polys to create the "hole" and with extra polys resulting from the chamfer, extrude a little and chamfer edges to get that rim around the hole...
i think that could do it... ?

Thanks for the feedback. That's makes more sense, but I'm not sure where to add the edges. Any chance of a couple of screen caps?

I'll do some more fiddling with it tonight, or maybe tomorrow...

There's a lot of edge-/chamfer-stuff in that stickythread. Honest! Scouts honour and everything.

[sledgeweb]

Yes, but it's all theory and broad examples... it might be useful to me if I could get a concrete grasps on it by solving my problem here, but right now, it's over my head...

OK, I know I can use the slice plane and insert more edges. This gives me the basic shape on the surface. Although it doesn't have rounded corners... perhaps it needs to be chamfered. Then I can neg. extrude, etc. But it doesn't leave me with a ring around the edge. As you see, I created an edge, but it's square. If I meshsmooth the whole object, it get's funky.

What I'm wondering is:

1) Is this the best way to go, or should I be doing a boolean or shapemerge thing?

2) How do I get the ring around the edge of the extrusion?

*bump*

Just hoping for more help. When the power comes back on, [been out since Saturday night (ice storm in Lexington)] I'm going to work on this some more - if my computer still works.

[jadedchron]

be a good idea to sift thru that sub-d thread then :z

[sledgeweb]

I sifted, and sifted, and sifted. Actually, I read the whole thing. But it's not helping me right now. I really need a dumbed-down example, then I can apply that to the theoretical sub-d thread. First, I just need to mess around with the basics.

Is it too much to ask for someone to post a couple screen grabs demonstrating this?

[Searcher]

Maybe it is easier to model that insert as a seperate model and then attach it in?

[sledgeweb]

I tried something like that. I created that polygon seperately and deleted the existing, and tried welding the new one in. But it messed up the curved surface of the cylinder. It made that polygon flat... didn't work.
