 Rhino 3D knowledge to students and professionals learning variousRhino3D techniques. We are going to talk about this  pendant designs today. 

I will showyou the detail of the top part. How I built each parts, and construct it intothe solid. We won't talk about the bail and a chain in this tutorial but you canfind a link below to see the detail tutorials on specificthe chain and the bail. Are you ready let's get started!   if you go to the Google and search forthe old design you will have a lot of black pendant  and white image which is actuallyeasier for us to trace in the Rhino so go ahead to pick up any of the  designthat you like as a reference. We don't have to build exactly the same, but someof the design have very intricate scroll design, for example, will be great for adesign reference. So pick up the image that you like, and save it into somewhereyou can find. And we'll use that to trace in the Rhino. so when we are in the Rhino.Let's go to the top view and type in "picture frame" for the Rhino 5, or "picture" inRhino 6.

 And we're going to the image that we saved. 

And bringing into the topview, you can pick up any of the image that you like. In this case, mydemonstration will working on the one in the left. So I want roughly to scaleinto the size that I like. In this case is roughly over...it's about 40 millimeter roughly, and we can always change the size later. Solet's go ahead to lock this one and since my image is black, I'm going tochange my line into... my layer into the red color, so my line will be easier (to see). My planis to use "sweep2 rail" command, so we will need to create a curve for it. Let'suse the curve tool and I wanted to starting from inside of this sphere, sowe can have intersect and  we can boolean it laterso let's draw the first one, then you can always use F10 or turn on thecontrol point to find the best curve on it. Alright so I'm going to draw onemore time this one we're gonna draw somewhere from here and try to find thebest curve here. Alright, here I want to show you a little pendanttrick instead of tryto trace this puffy part. I usually like to use the blend tool because it's comeup better. I'll pick up this end and this end, and you can also edit the controlpoint to make sure it fit well. Once you have done that, you will have threedifferent section.

Let's go ahead to hold the SHIFT key and join them together.

After joining we would like to split into half, and you can always make surethat your Osnap either is on the midpoint or the quadrant is on, and weuse the point to separate them into two half. So those two will be our rails andlet's go to the perspective (view) now. we need to make a cross-section, so let's usethe "arc" tool and in the arc tool, on the third one, is"start, end and direction" of the arc so we will do is we will go into theperspective (view) and let's snapping to the end point and the end point coming to theright view, and holding the SHIFT (key) so that way you pendantwill have a 90 degree. Alrightso to create this surface, let's go to use the.... under the "surface" you have "Sweep2 rail", and this is gonna be rail 1, rail 2, cross section, and that's how weget this really smooth surface. Alright, then the rest of the 4, I'm going tofast forward here, so you can see in the fast pace here. but it pretty muchwill be the same. As you can see here. I try to trace all the lines for our railsfirst, and you will need to reuse the the first model or the first shape to reusethem so rail, so after I create a first shape I will need to explore it thecurve back to three sections, and use where is overlapping to be the firstrail on all of them, so you can see how I built this with "Sweep2 rail" command.

This is a nice model, but one thing for metal casting is... if you look at this profile its connecting this way. That means this is almost no thickness onwhere is connected. That means when you are casting. It may cost the issue sowhat I'd like to do now is just a little bit change there. I'm going to close allthe forms first, and make them into the solid, and try to overlap and scaleit up a little bit. It might changejust a little bit, but it will make pendant your model cast much better. So I'm going toclose this one and this one right here. so making another surface. We are goingto pick up this curve and this curve and the command I'm using is living undertheir surface, and this is "surface from the planar curve" that's the command I'musing, so pickup 2 curve and close this end here. and the reason we wanted to dothat is I'm going to use a "cap" command but need to make sure that it's only oneside is flat and it's opened. You cannot have two side open to do the command.So I'm gonna do that to all of them and now what I'm doing is try to jointhose surface together, and then we can use the "cap" command.

 Let me flip it to theother side, so we can see better that's hide one. Alright so now we canuse the CAP command to cap all of these. okay so now we have this as I wastalking about earlier we need to kind of scale it up a little bit, and I'm gonnabring it back to my drawing here. I don't want to be too much difference,because we scale it up we can kind of bring back together like this. So theyare kind of overlapping which also create a thickness in between. So I'mgonna bring this back here a little bit. and bring this one back here. Alrightso you can see they're overlapping and if pendant we are we're selecting all of them and use the "boolean unit" so there will be a goodpiece and has a thickness on it. Even though we are going to mirror to theother side, it's also going to increase the thickness, and I will ensure a bettercasting quality. Now I finish this part on the top I'm going to just drop asphere roughly about right here, and we can scale it later once we mirror to theother side. Let's work on the part in the middle. Let's go ahead to lockthis one that we already did, and for the second the middle part, we are stillgoing to use the "sweep2" so let's creating the first rail roughly aboutright here, and you can always turn on a control point to adjust the points to fitinto your design more.

 And this one is just for our reference, so I'm not gonnamake a hundred percent fit, but just want to show you how I do it for theadjustment. Once we've done the first rail. The second rail we are going to goroughly from here. Again, try to follow your design aspossible. In this case, it's not gonna be 100%, but one thing I would like to dohere is make sure that it's get inside of this shape there. The reason is thesame, we want to make sure that it's gonna be pendant overlapping, so this is somepart that overlapping so we can do a better boolean unittogether so you can go ahead to adjust the curve to make sure that it fit wellokay so then we are going to creating the circle. I'm gonna use the diameterbecause I'm going to snapping into the endpoint right here and right here.Now you see that's a circle it's what we want it to be vertical so going to thetop. There's a vertical, you click on it. It will be vertical right there, andlet's do one more time, endpoint to endpoint, before you click on thesecond one you want to use the vertical option.

 So let's take a look on theperspective so here's what we have on that, and I'm going to use the samecommand "Sweep2 rail" and this is our rail 1, rail 2, and cross section, crosssection. so then we can have something like this. Alright,you can also.... one things we can do is before we do that, we want to "recordhistory", and let's do one more time "Sweep1 rail", rail one, rail 2, crosssection, and cross section. So now once we have done. and if we feel like okay thisis not too good of the curve, I can always turn on the control point, andedit. So that way you can make sure the the form is intersect with it, or youfeel like okay this curve might be too bumpy, and I want to move a little bit soyour shape will follow it. Okay and you can spend some time to find better shape. Okay so now we are done with it. I'm notgonna spend too much time to adjust it. Let's go ahead to finish with twospheres. So let's go to the top view and I'm going to drop two sphere right here.First one is roughly going to be here, and it's roughly going to be that bigAlright, the second one will be somewhere herelike this big here. So let's go ahead to cap this one and it will say you breakthe history.

That's alright, because this is already perfect and we don't need tochange too much.

 Alright so once it's CAP, I'm going to boolean unit thosetogether. Alright so now it looks okay but when you're looking at the renderview, then you're going to see this line here and it's not gonna look good. Let'stake a look on it so what the goal is try to make it look as smooth aspossible, so we're gonna go back to the ghost view, and right here we're gonnause the fillet command right here. Let's go ahead to fillet. 1 might be toosmall, let's see. Yes, a little bit too small, so I'm going to try 2.25 and see what happened. Alright it looks smoother so I'm going to try 2.5 here as well. Okay so now we have this one. Let's do a little bit test here.Now this is the showing the high of our first part. The second part apparently isa little bit too fat, so I'm going to do 1D scale down, so it will look something...it's more appropriate to the first part that we have.Maybe a little bit thicker right there. alright so that was the first part, andI'm just gonna simply mirror to the other side, using the endpoint as my mirrorpoint, and let's mirror this one to the other side, alright so now we have donethat part, let's go ahead to finish the third part. For the third part we aregoing to separate them into the three section again.

 So first section that'sgoing to go from here. That will be our first section, and let me make themsmoother okay the second line is going to go fromhere. And don't forget to make sure that has intersect. So this is roughly will bemy second section there. Alright and you probably kind of guess what I'm going todo here at a tip. Instead of trying to trace it I'm going to use the blend toolto blend it together. So that will ensure a better smoother form. Alright so now Ihave this I'm going to join them together, and actually I'm going torebuild this one. It's another trick here to show you rebuild. You canrebuild it's really close to what everybody has. But by rebuilding, itwill make it much smoother. So look at this part has a flat section, so nowI can move it out a little bit and all other form will follow. so it will besmoother. And of course after rebuilding, you kind of need to adjust what you havethere to fit into your design, so here's our perspective we are going to use thearc and then we're going to use the third one "start, end, and direction" sohere's the arc and let's take a look on the right view.holding the SHIFT, so that way we have the cross-section vertical. And with thisone let's split into two.

 So rail 1 rail 2, so using a sweep 2 command,rail 1, rail 2, cross section, and that's how we get that one. We wantto close this form by the command for "surface from planner curve".We're gonna have this curve and this curve and join them together, and "cap"them. Alright so now I can just simply mirror this guy back to the other side.so now we only need to.... the last part we need to do this section here is the toppart. So what I like to do is go back to the top, then we're gonna draw a line, a curve.Let's go inside of this form so we'll ensure we have a better boolean later on, andwe want to mirror that to the other side okay and try to blend again. I use a lotof blend in this tutorial, I just want to show you a different way of how I workwith curve, and we want to go to the perspective, and then let's go ahead touse the the same command for the arc and the snapping into the endpoint,endpoints, holding the SHIFT at the right view and to create this arc.

Let's goahead to split this into two, and we want to split with the point right inthat quadrant, so we cut those and let's go ahead to Sweep 2, So this is therail 1, this is the rail 2, cross section. Let me go ahead to close thisshape. on surface from planar curve and that's join those two and cap aswell Alright so now we have all the partready and we can simply just boolean all the parts together, but before we do thatwe want to check the thickness if that is what we want. So let me hide thebackground and let's take a look at this one. Alright so we want to take a lookon the side (view) and make sure that they all look nice, before we do all the boolean.So I'm going to pick up this shape and this shape.Let's go to the right view and we want to pick up the shape over here, and let'sgo ahead to do the mirror. Alright, so the middle part, it might be too much. SoI would like to scale it down a little bit, so it's not stick it out too muchright there, and rest of it look nice so we can boolean at this point. The finalpart is actually quite easy. Let's turn down our drawing again, and I'm gonna doa little bit change here.

 I'd like to have a cylinder and simply snappingsomewhere in the middle. somewhere like this, and I can just haveit pick up any of the shape that I have. Somewhere about the one in the middle. Solet me pick up this ball here, and the cylinder, and let's do the align. So nowit's align, I can do 1 D scale it down. Maybe a little bit wider. Okay and you canalter your design, if you need to. Let's give it a little bit fillet edge to looks nice. Let's go ahead to do another cylinder, and this time, Iwant a snapping into in the center and then roughly about this size. Alright sothe very last part... oh... we want to giving a little bit radius, so it looks nicerthere. Alright so very last part we're gonna use the straight line, holding theSHIFT coming back here another shape will be right here and with those two shape, I'm going touse the command in for the corner fillet "fillet corners" and then they set it upfor... try 1.

 Let's see how it turn out. And right here maybe I need to have abigger radius. I can simply just pick up those 3, and delete them. So they willcome up a very large curve there. Let's go ahead to extrude those two shapes bygoing to "extrude planner curve" and pick up this one, and that one, and wewant to make sure they both solid, and we'll be right there. For pendanta betterrendering, I will suggest you to giving a little bit fillet edges both top and thebottom. Alright we can now turn off the background so I'm goingto unlock it, and hide it. So now this is our key. The only thing left for us todo is Boolean, so this is the tutorial today for making this key. I hope youenjoyed please comment below let me know how you doing, and if you have anyquestion that I can answer for you.
