Some help please

Here's a Tutorial on doing it one way...

Dave R · 28 Feb 2008, 14:47

Thanks TIG. You beat me to it.

Mike, do you still want me to do that for you?

GreyHead · 28 Feb 2008, 15:44

Here's an example - the method is pretty much the same as Dave R's except that I intersected one link of the chain with the plain band to get curved surfaces. Looking at it the band is a perhaps a bit thick.

In a similar vein here's my tutorial version but with a rectangular extrusion rather than a tube...

Made one ring and copied an array using the protractor multiple paste method.

It seems everybody wanted a piece of this one...
Here is my tutorial.

Thanks for all the input guys, I'm sure that I'm gonna have some more questions as I continue.

just in case it's meant to be braid-like.... i guessed a certain reference point which was close but not totally right.. if i have to do it again, i'll be able to fix that..

alpro · 28 Feb 2008, 18:15

Yes Jeff, that's exactly what I was looking for, I guess I should of said braided instead of intertwined. I really appreciate everyone's help on this.

i don't have time for a tut right now but i can show you how i did it later.. in the mean time, it looks like a lot of people are into trying this shape so maybe someone else can do it..

for now, here's the skp of my version..

ok, so i figured out how to draw it more to my liking but doing a tutorial for this thing might be a little bit much.. it would be about 25 scenes with weird to describe curve manipulations in there.. if someone really wants to see a step-by-step, i'll do it but i'm going to hold off for now.. it will probably take ~2hrs to put together..

it's sort of similar to TIG's method except i used two circles to begin with instead of one (one inside of the other).. i then alternate between the two circles which allows for the weaving..

here's the fixed version skp..

With our combined IQ well in excess of 'genius' we have got some great ideas here.

Alan Fraser · 29 Feb 2008, 09:12

I haven't had time to go through all of these, but it seems that you might also be able to do it by producing a ring of braid that is only skin-thick, then using Vector PP on it. Did anyone try it that way?

eric,

why step 8 (intersect with model)?

TIG,

great tut. could you tell me what happened from step 8 to 9? the circles are smoother and the proportions are different.

alpro · 29 Feb 2008, 13:09

This is why I love this forum, so many people willing to share their time and expertise, that just doesn't happen on any other forum, this is definitely a community. This is also why I love SU, so many ways to get the end result.

If you read the notes on page 8 you'll see that I based the steps on 8 sides with no scaling to make ellipses. Then I just re-did one on page 9 with 16 sides and scaled a bit flatter. I didn't show the steps as it would have taken too long... It's quick to do, but slow to de-construct into a tutorial step sheet...

GreyHead · 29 Feb 2008, 17:29

Here's a version done with Alan's suggestion for Vector PP. The model looks good.

Because if you do not then the points where the components intersect each other will be visible.

I tried the vector push pull but got some odd results. Maybe because my curves had a large number of segments.
