Rhino 7 SubD Fleur de Lis ring

hi i'm travis serio with robert mcneil and associates and today i wanted to show you how to build a fleur-de-lis ring in rhino 7 using the new sub-d functionality this is pretty cool so check it out all right to start i need to draw a fleur-de-lis and i'm not very good at that without looking at something to trace so i'm going to come up here to the viewport layout tab and click on this add picture plane and through the power of hollywood i have a fleur-de-lis right here ready to go so i'm going to draw this out into our top view and then just sort of haphazardly align it center-ish how's that and i'll scale it down a little bit and then in the front view i'm gonna drop it down below the z a little bit i'm going to start tracing over this thing and i don't want the picture frame and my sub d objects kind of fighting for who gets to be on top so we'll push that down a little bit the next thing i'll do is i'll switch it to this other layer and then lastly i want to click the paint tube here and adjust the transparency so that i can just see it and that way i can see my grid and stuff through there finally let's lock this layer so that i'm not accidentally selecting it every other moment okay so uh if you're already a rhino user you probably have seen this shape and you would say i would draw a curve here and maybe mirror it to this other side a couple cross sections sweep sweep done right so that's certainly a great approach and um one that you know we'll get it done every time and look really well i want to do this with a sub d though so that we have a little more flexibility over some of the push and pull and so i'll travel up here to the sub d tools and there's a few different ways we could do this with sub d i mean you could still draw the curves and sweep it and then convert those to sub d's or sweep as a sub d up here but um what i wanted to show you is how to do this sort of flat and push and pull the faces around and then thicken that up and so um that's a really popular workflow uh known as edge extrusion uh or face extrusion so let's do that one way we can do this is with a single face and that lives right here and then we can append to that face and extrude out edges the other way is we could start with a simple plane and since the center part doesn't really bend like these edges do i thought it would be fun to do it with a plane and i've already like a good cooking show have this set up to two by six i think i tried it two by ten and it was too many and then i did two by six and it worked pretty good so uh like all good cooking shows we'll just go ahead and draw that out here and then i'll sort of align it with what feels like center there now if you've watched any of the other sub d videos and i hope you have by this point you'll know that control and shift lets you select either the verts or the edges or the faces in our case uh we were in wireframe so you couldn't see the face but i've i've switched this to ghosted so what i'll do is i'll i'll just drag select with ctrl shift selected and just using the gumball start to just scale these to where they fit our shape going from top to bottom i'm not super concerned with the first pass of them lining up perfectly we'll come back and push and pull a little bit more to make them fit a little better so we do the first pass and then i usually go top to bottom and then back up once the once the shape starts to look more refined now i'm a little larger and i think this one could move up and then possibly oops possibly come in here a little bit all right i'm not going to fuss with this too much okay so there's the center shape done relatively quickly just by using a basic plane we could then take that and use the offset sub d command up here in the sub d toolbar we'll offset at a distance of one it's traveling up in the z axis which is good i don't want both sides enabled here i do want solid equals yes so we'll say go and shade that and we can see that that's extruded everything nice and solid for us but it's left us with this hard crease so i'll select that edge loop of the crease and click remove creases so this turned out really nice and it reminds me of one of those spoons you eat like the little ice creams with out of the maybe i'm just hungry um so let's do let's do an edge in here because the floor has sort of these sharper lines uh down the middle of them and i want to recapture some of that so we can use the insert edge loop and i'll select the main one running down the middle there and i'll right click and then i want to make sure that i have both sides equals yes i'm in proportional mode over absolute i like this as it's kind of giving me a nicer flare here than um absolute it absolute's trying to keep me that set distance apart all the way and so i like that it keeps the top a little better there and proportional so i'll go with that and then i'm holding ctrl shift and grabbing that center point there for both the top and the bottom and that gives me a little bit of definition and contour like i want if you wanted it to be sharper than that you could either add more edges through there uh or you could sit and refine that edge spacing to give you the look that you want okay so we're going to call we're going to call this one we're going to call this one finished so that was with the the plane the next thing i'll do is with just the single face and so let's go back to the top view we'll come up here and find the single face which is right here and then i'll just draw one to get us started so we're going to pick four corners and tada and so that gives us just a single face if we hit tab we can see the four corners here in the box mode or even if we hit f10 to turn the points on we can see where that lives it's a little harder to kind of point and grab those individual points when in this mode i got lucky right there sometimes i pick the edge to where i can see where that point is going to be and then i can i can jump in there and get at it but what i'm going to do now is i'm going to run the append to sub d command and then it wants to know what we're going to append to which is our new face and then i'm going to do some some command line tricks here and make this thing do some other stuff yours will probably say n gone in the polygon type by default so as we extrude out here it'll want one two three four five six seven eight is it's gonna go on until we right click to stop but i want it to know that i'm done drawing after i make it to a quad so we'll change that to quad and then i want to do it from an existing edge so i don't really have to snap to anything so we'll say that's good and then multiple faces are good so now as i move around out here since i told it to use from edge you can see it highlights those edges so i'll click on one and then i'll immediately just start picking the next two points since we did quad it knows the first two points are chosen for us already from the edge we started with this edge so that's point one and two and then we're just establishing points three and four and then if for some reason you mess this up uh you can just do undo up there and then rhino forgives you and you're allowed to continue see i don't i didn't like that so let's do this one more time and there we go okay i won't fuss over this too much uh so this looks a little goofy we'll come back and clean that up but i'm going to select the the piece here and click append again and then just real quickly i want to do the bottom portion and you know when you're not um when you're not talking about it and just doing it you tend to get it done pretty quickly all right okay so now there's really a lot of uh faces in this thing or i like to think of them as a little brick pavers in a sidewalk for whatever weird reason so sometimes defining these smooth curvatures can be much easier if you don't have quite as many faces to contend with so what i try to do is i try to delete some and see how many i can get away with deleting before i get myself into trouble and i can't make the shape anymore it's always easier to control this stuff when it has fewer edges and faces in it i couldn't really see where those end ones were so that makes a good reason to go with the box mode okay so we can keep chasing this or we can just say that it's good enough for our tv broadcast here like any good cooking show okay so let's let's say that this is this is good enough um it's really not but i want to fix that inside edge but i'll leave it alone okay um i want to repeat that offset again this time the arrows are pointing in a direction that i don't want so we're going to say flip all and go ahead and hit go just like before remove those edges now to get this sort of sharp crease in here we need to get an edge loop running right down the middle and um if we if we double click this and say okay uh first let's not do both sides it it doesn't it doesn't loop through like like i want so that's no good if you look at the icon here on left click it does a loop and so a loop is when the edges are end to end if you look at the right click tool tip it says an edge ring and a ring is more like ladder rungs uh where they go this way like the cross sections so i'll right click to get a ring and then if you just pick one rhino is super smart and figures out that you probably wanted all those which i do so then we'll say okay and again i'm in this proportional offset mode because i like it and i want to go i want to kind of go out towards the edge here and i'll show you why in just a second now i want to take that one instead of right clicking i want to left click this time and get that loop and then i'm going to come back in towards the center and maybe this time i do absolute so that i can drill down exactly where i want it and i'll put it there and so this gives me two loops that are kind of near each other that are going to create a lot of dramatic influence as we start to play with them now if you if you double left click this it can be hard to sort of hold control and deselect that stuff without deselecting everything but if you go into selection filters here and put it in edge mode if you double left click that now when you hold control and fence select those it unselects what you're looking for there and i'll pull these up and then i'll pull these back down and start to create some of that inner contouring so that makes that a little sharper okay and i and i told you i wanted to fix that it's just making me bonkers all right i promised myself i wouldn't get lost in the details because it's easy to sit and explore shape with subdi that you kind of gotta know when to just leave it alone and finish it okay so that got a little bit thicker so i can just do that and scoot that down and then we could mirror this to the other side and then for the band across the center there i think just a simple primitive cube would get the job done so let's come up here and say we want a cube we've got two by two by two that's fine for me i'll make it a little larger than what we see in our image here i think to square off the bottom a little bit i'll do that i'll hold um control shift and just sort of flatten that out well it's sort of like a twinkie shape there then maybe up here instead of extruding i could just scale it inwards a bit and then maybe maybe we pull it down a hair to give it more of a bend okay that looks that looks pretty good we could sit and add more detail we could add some ribs to this by um offsetting both sides here and then pulling in the center and start to give it a little bit more of a little more flair to the floor okay we're finished with our image now let's see i haven't really paid much attention to scale and the other thing that i haven't paid much attention to as to how center we are with the uh well that's pretty close but um not bad for not paying attention um now let's put a put a ring out here and get this thing connected up so i'll make a circle from origin past 0 here and then 16.5 is a u.s size 6 so i'll just right click and accept that and now this is only about uh a little under a millimeter so that's that is no good at all so we're going to transform that again and what i want to do is i want to scale it 1d up a little bit and then i also want to see how big this thing is it's pretty large across the top so let's um let's scale this down some and we might actually we might pull all this down a little bit okay so that fits up top pretty well again with the scale 1d and so that should go across the finger pretty well in fact let's go ahead and these aren't quite sitting on the finger rail neither is this one and then there's our cube let's take all of this now and we'll run the transform bend and i want to find the quad of that circle hold shift for ortho i've got symmetric equals yes but it looks like i've got a funny snap there so let's say into the quad there we go now our bend is looking a little better i'm going to snap to the other quad point now we know we have a nice arc going down okay so now it's conformed to the finger rail there's there's certainly some more refinement that could be done to the shape which we can still do but i'm going to go ahead and just draw a two point circle from the edge here two millimeters thick and then we'll run a sub d sweep one on this rail and this cross section all right so here comes the shank and we're set up at eight by eight and that looks good if anything you could decide whether or not you wanted more cross sections in it but i think eight by eight is really good so we'll go ahead and say go there and then selecting the faces i'll just delete those okay let's hit delete and then i just want to fill this hole up and so i'm going to click fill hole and this is the boundary i'll right click and i'll select automatic and rhino did an excellent job there of figuring out a nice quad patch at the end so next i want to connect these two together using the bridge command and so with faces still selected i'll do these two but we only have one here so let's go ahead and grab this edge we'll turn off the selection filter let's grab that's not going to work we need to use the ring so we'll say that's our ring and we'll just go right in the middle and then let's go ahead and go back to faces so u and u will bridge to you and you oh yeah i never get tired of that and then holding shift you and you will go to you and you so let's repeat the bridge and there we go now uh instead of doing all the hard work again let's just run reflect so we'll say reflect along the y-axis keep this side right click and there we go we could also go ahead and just start establishing that everywhere so y-axis keep the side go why not you as well y-axis right click oh i got too speedy click that side there we go i forgot to click okay so now um let's get rid of this crease that's on here i don't really care about that anymore there's still another crease sort of shooting through here so we'll get rid of that and then if i select both of these we should be able to just pull that down back onto the rail um in hindsight i would have made that just a little bit thicker but it's going to work for uh for our example here and so there we go it's it's ready to go if we wanted to square up the finger hole a little bit we could pull these edges out and then it'll be less round but still like a comfort fit on the inside then lastly let's go over here and find a material so let's say metal and how about silver but i'll make it just a little bit lighter assigned to objects record mode there we go okay well i hope you enjoyed it and you learned something from this and thanks for watching
