 Hey what's up folks welcome back to another layer by layer in today's tutorial we're going to take a look at making some Kumiko inspired patterns on different projects. So Kumiko is an awesome Japanese inspired technique of woodworking, creating these really fun patterns and I thought it'd be kind of cool to show folks in Fusion 360 how you can kind of create some different patterns. So the traditional way to do it is kind of with these thin strips of wood but in this project I kind of have it wrapped around the cylinder to kind of make a bit of a of a vase or a vase or a planter. Anything cylindrical that's kind of a neat way but I also wanted to show folks how you can CNC mill some engravings of these patterns on some tiles. So here I have this in the render workspace and I'm just kind of showing off this wood. So if you wanted to cut this out of out of some wood using something like an engraving bit this is a kind of a fun technique to do that. So well let me jump back into the design workspace and kind of talk a little bit about creating the shape. So in Google you can kind of search for it maybe get yourself a Kumiko book that gives you the dimensions and the degrees of how to create these shapes and there's a number of certain patterns and the pattern that I've chosen for this project is the Asanoha. So the Asanoha is kind of like the the hollow world I think of Kumiko woodworking. So let's go with that. So the Asanoha shape is what we're going to do. So let me start a new design and the first thing I want to do is pull up our user parameters and we're going to create something called like tile size. So I want to do the size of our tile and let's just kind of make it a hundred millimeters. I'll do another one. Let's do the tile height how thick we want this thing to be. So I'll put 12 millimeters and then I'll put here the the engraving depth or the cut depth. So the cut depth how far we want to cut our pattern into our piece of wood. So I'll put two millimeters and that's it for now. So those are the user parameters that wouldn't work with this. So hit OK and I'll create a sketch. It's going to be on the floor plane here and I'm going to use a two point rectangle just a basic rectangle. But what I want to do with that rectangle is have it centered in here into this into the center origin of our grid. So I'm just going to draw out a rectangle and I'm going to worry about dimensions just yet and you can see here that I can drag this around and it gives me some nice horizontal constraints and the next thing I'll do is I'll grab one of these select one of these lines and then give it a dimension by hitting the D key on my keyboard and instead of typing out a value we already have one so I'll do the tile size and hit enter. Now we want this to be symmetrical so what I'll do is I'll select this line and that line holding down shift so it selects both of them and then I'll apply a equal constraint the meaning that both of these lines will be equal. So hit that and now they're equal. So now whenever I change this dimension here and I use a parameter panel this whole shape will change. So now the next thing to do is how do I get this rectangle to be perfectly in the center of this center origin? Well one cool thing is we can use lines to do that for us in constraints. So I'll bring up my line tool I hit the L key on my keyboard and then I'll just roll over one of these until I hit this little triangle. The triangle lets me know that's the middle and if I click that that actually locks it to the middle with a midpoint constraint. Now I'm just dragging my mouse don't click yet and if I start dragging over here you'll see I get a little little plus sign here and that's the middle don't click that yet if you just drag over you see fusion starts giving me a dotted line and that dashed line kind of lets me know that it's guiding me straight so let me keep going until it locks it there so it's nice and horizontally constrained so I can click that and then just finish off by closing it out with that midpoint constraint there and now we have these two lines that we can use now if I select click and drag I can just drop this onto the center and now it's locked in place excellent next thing I'll do is I'll double click on one of these lines it'll select that line there and then on my keyboard I'll hit the x key or this one here this little icon here and it'll change it into a construction line and that just makes it so now these lines are being used for placement instead of like actually cutting sections of my rectangle and that's it now we have our tile ready to go so I'll hit the e key that'll escape me out of the sketch mode and bring me up to the extrude and I can start extruding for the distance I'll type in the height the tile height that we set and that's going to be 12 millimeters so hit okay and now we have our piece of stock ready so let me hide let me name this let's call it base profile I think that that works well and then I'm going to use one of our construction windows here the construction menu there's an offset plane so I'll click that and then I'm going to click the top surface of our tile and then I'm going to go negative because I need to go down and then in parentheses I'll type out the the cut depth and then enter that and you'll see that it's two millimeters going down and that's where we want it so now we can actually select that create a new sketch and then this is we're going to start creating our Kumiko Asanoja pattern so let's bring out the line tool and basically what we're going to do is we're going to start by creating kind of like a quarter of the shape and then kind of use patterns circular patterns to kind of complete the shape for us and since we're kind of creating tool paths infusions manufacturing workspace we've got to be really smart about the elements and if we were to draw out the whole shape we actually won't be able to select that as as as entities for our tool path for our engraving tool path so we need to kind of do it piece by piece so we'll start with uh with doing kind of one one triangle so I'm gonna start from the middle I'm gonna go up go across and then kind of close it off making this kind of triangle shape next thing I'll do is I gotta give it some dimensions so I'll give this line I'll select the line give it a dimension and you can see it's 50 millimeters that's half of our tile size so let's give it a real value parametrically so I'll say title size divided by two and that's it for that next up well I'll put a a degrees I have to say hey how much degrees do I want for this line so I'll say I want have to hold on shift select both of these hit the D key and that starts doing the dimension the degrees so I'll put in 45 and that's what it needs to be and then going back to the line tool let's go ahead and make a line from this corner and we're kind of kind of do something around here and then kind of close it down to this corner okay and then the the next line will be from this this corner to this top corner there all right now you can see I can kind of drag this around and really you only need to do one more degree and I'll select this line and this line give this a degree of basically 45 divided by two and that's 22.5 hit enter and then instead of applying this to like this bottom here like you could do that but actually what we need to do is say hey you know what this line needs to be equal to this line and that's it it locks it in and everything's perfectly symmetrical now so I did that with the sketch shortcuts on my keyboard I have it set up to the letter s and that way you can just type in anything you want you know any constraint you want equal collinear it all shows up there which is great and these these two lines were done with the equal constraint or you could use this up here at the toolbar your constraints are all up there so that's one piece of that triangle and instead of doing it in this same sketch here the second piece to kind of finish off this this quadrant I'm going to hit finish sketch because infusions engraving toolpath you really kind of have to have it piece by piece so I'm going to name this sketch call it pattern a and then we'll do pattern b so let me create a new sketch and then go under here in that plane that offset plane we got to select that same plane because that's where our our cutting depth needs to be so select that construction plane you can see here it's going two millimeters underneath our solid tile and now we can kind of do that same song and dance right so I'll get my line tool and let's go ahead and just hide pattern a and instead of doing this side we're doing this bottom side so we'll start from the middle go across go up to the corner there and then finish off in the middle do our same thing where we can give one of these lines a dimension parametrically tile size divided by two and then we'll do a dimension degree right here 45 hit enter and then we'll do our lines again so start off in the center somewhere up here and then close it at the top and then one middle one go into this corner here same thing we'll do a 22 degree 22.5 degrees and then add an equal constraint to those two lines and now it's ready hit finish sketch let's name this pattern b and those are really the main two elements two sketches that create the the asinoha pattern so at this point we're ready to go into the manufacturing workspace because we are going to do tool paths for cnc engraving so I've got to create a setup and depending on your cnc you'll have to pick well which center of origin how you want your your stock to be set up so I'm going to select this corner in the lower left because that's how my cnc works switch over to the stock tab and let's go ahead and zero out these these offsets for the top and bottom let's say our our tile will be exactly the right size are ready to go so we won't have to worry about cutting out our shape because it's already set as a square so our setup is ready and now I'm going to bring out the engraved tool under 2d hit engrave let's bring this out a little bit for the tool you can create your own tool or you can download a library from the manufacturer of the tool bit I got one from bantam tools they have a whole slew of these and basically I took the 80 degree I right clicked and I hit copy tool and then I changed it to be a v-bit and I'll select that and let me go and show you this v-bit I got this from eventables and this is a carbide v-bit 90 degrees this is interesting because it has a quarter inch cutting diameter inside of an eighth inch shank and if you know the bantam tools that pcb mill it only can do an eighth inch tools when it comes to the shank so this is a really nice tool because it gives you a wider cutting degree than your shank which I think is really cool and this is meant for a really nice carving and the v carving is exactly what we need for this project so pick this up if you got it and if it works you're cnc mill that's awesome so going back over here I have my tool selected I'm not going to worry about the feeds and speeds because that's going to depend on your material whatever you're cutting so I'm just going to leave that by default and really we need to go into the geometry tab and start selecting our stuff so as I roll over some of these shapes you'll see how fusion is kind of interpolating them and saying like okay these are one element this is one element and this is a whole element so let me bring out the actual sketches and just reveal pattern A and I'll work with pattern A first so unfortunately we can't kind of do all of them in one go we have to do them piece by piece and you'll see why in a second so I'll select this piece and by default if we go to the heights tab the bottom height has a offset and that's going to ruin our pattern so I need to zero it out and that's the only thing we really need to change nothing in the passes it doesn't need to have any multiple depths because we're just doing such a shallow cut at the v bit just needs to go down and plunge do one depth and not multiple depths but that's it you just really have to clear out that bottom height and your geometry selected you just need one shape and then hit okay so then you get a little preview and if you go into the simulate tab you can go to the end of the tool path and see how uh how this shape turned out you can see okay it looks great look how wide that chamfer is it's really really nice you hit play obviously and see how it's going to do it very nice clean you know uh path very clean path it's very simple so let's hit exit simulation and let's make another one grave the tool's already selected for me because fusion kind of thinks like hey that's the same tool go into the geometry tab and pick a different triangle let's pick this one up here and then we we got to keep doing this heights and then here at the bottom height we got to clear out that offset so just put zero and hit enter and that's kind of it for that so now we got that bit and then we just need to do this last triangle here um so engrave geometry select this now you'll see that it doesn't actually select kind of this thing it does this whole thing here this whole triangle but that's fine that's actually okay so i'm gonna leave it that because that we just kind of need this line these other these other three lines we created for us already we just need this one here and even though it's going back again on this line it's kind of going to clean it up for us a little bit so that's kind of nice again we got to go to heights and we got to clear it out so we have to keep doing that but uh we won't have to do it for all four quadrants because we'll use a circular pattern and that's it for that so that's okay now we have our three individual engraving tool paths and if we have the setup selected like that and hit simulate we can kind of see them at the bottom here run through it go to the end you'll see okay that looks good very very good and uh let's hit exit and now let's hide pattern a the sketch and bring out pattern b and we're going to do the exact same stuff so engrave tools already selected let's select our whole triangle here heights zero out the height okay create another to this shape heights zero it out hit okay we got one more to do engrave geometry select your shape go to heights and then zero it out and then hit okay all right we end up with six individual engraving tool paths and if i hit the setup go to simulate and you can see at the bottom here that either they're individually selected because they're doing a group of engravings but at the end of the tool path you see that's exactly what we want if we hit play that's pretty much real time speed of how it's going to go very very fast not a lot to do there so uh that's really nice and at the end there you'll see that that's just one quadrant now we need to create four of these copies in a circular pattern and let me show you how to do that so let me hit exit simulation i'll uh click on one engraving hold down shift and click the last one that'll select all six of them and then right click on that engraving one and then right over here under add to new pattern and select that and that's going to make a pattern now we want to change the pattern type from linear let's make it circular and now we need to select an axis so let me let me pull up the origin here it's hiding under the models let's open the origin i'll zoom out a little bit to give me a bigger view of that z axis that's what we want to select the z axis so with that select i need to update the the number of instances or the copies from two let's add four leave the angle at 360 and hit okay that's that's all we need to do there in order to kind of preview it though we do got to go in the simulate mode so let me click simulate and then over here go to the end of the tool path and then fusion will render it for me and look at that that looks freaking awesome that is exactly what we want so now we have our parametric tile we can change the depth cut we can change the tile height all that stuff through a user parameters and this is a really quick way to kind of create a kumiko inspired engraving with cnc which looks out really fantastic so this doesn't take too long it takes maybe five minutes on the mill depending on your feeds and speeds but it's really cool that it's driven you know with parameters and uh it's it's it's patterns and stuff and when you break down you know patterns by its element it becomes a lot more i think efficient when you're when you're planning out your tool path so that's all cool and everything that's great for cnc milling you can right click and post process get some gcode out of that and run it on your mill which is super cool but if you go back to the design pattern you'll notice that there's nothing here everything we did was in the the manufacturing workspace for for cnc milling uh in my kind of fun experiment you see i created this in the actual design works we actually modeled this stuff so i'll show you how to do that and i'll give you a quick look here if i go to the end of my tool uh my timeline you can see that i have this kind of fun art framed bit where i took uh nine of these tiles and my idea is to make nine of these different ones and then cnc them out of different uh species of wood and kind of create this checker pattern and then maybe a frame i think that'd be cool but if you want to you know render it out you still have to figure out how to create um a full you know shape here in the 2d workspace uh so let's do that in the same thing here uh so we'll just use the exact same pattern so let me uh keep this open and i'll hit the extrude key so we'll start extruding not don't select anything yet because you have to change the type from extrude to thin extrude it's a very special uh extrude and i'll start selecting these lines individually like this and now they're all selected um i can go under the wall location i want to be center because i want this i want my extrude to kind of come out from the center of this and for my distance here i'm going to put four millimeters and you can see that it's going there like that and i'm actually going to change the wall thickness to also be four millimeters now i'm going to change operation from cut to new body and that's to create a new body and i'll hit okay now i want to differentiate myself from these two bodies so let's open the bodies and you can see here we have body one body two and i'll bring up my appearance's panel to change the color and under solid wood unfinished i'll give this a maple and that looks cool okay next up uh let's hide pattern a sketch and bring up pattern b sketch and we'll do another extrude change the thin extrude and select our lines again let me hide body two and then select that last line using the exact same values we want distance to be four wall thickness to four the side needs to be center it needs to join but not body one let's hide body one and bring out body two and we want it to join with body two so i'll hit okay and let's hide the pattern b sketch now you can see here i have a couple of these spiky edges so let's clean them up by just holding down shift and then we'll select the faces that are kind of a part of that spikiness so like these here like this and fusion does a really good job of kind of cleaning these out so i just selecting holding down shift to to kind of do the group select and with all those surfaces or faces selected i'll hit the delete key and fusion does a great job of just removing those and keeping it healed and it's even a a thing here a feature in the timeline which is cool so that's our first quadrant and we need to kind of make another circular pattern but of the body so let's bring that out i'll type in circular and select circular pattern it's going to be this body my axis is going to be z again so that's that blue line and my quantity is already updated to four angular spacing is full hit okay so now i need to group or combine all of those copies together so let's use combine select them all and we'll change the operation from cut to join and i'll just join those together here cool and now i'm going to hide body one and i'm going to look underneath our kumiko kind of shape and i need to apply a chamfer but instead of selecting all these individual lines i could just select the surface and apply a chamfer to that so let's do that chamfer and then i'm going to put one now you know the thickness is two millimeters because our wall thickness was coming from the center but if i put two fusion craps out and with an error so i'm going to give it a little bit of a hack so instead of putting two i'm going to put 1.999 and fusion will just say okay that's totally fair and i'll hit okay and that's a little hack that you have to do sometimes with the chamfer but it's a perfect chamfer all of these edges now have been chamfered and that's awesome way better than selecting them individually let's bring back body one which is our tile and now we got to do subtract these two from each other so i'll do that with the combine my target body is our tile and our cutting tool or our tool body is the thing here let's change the operation from join to cut you kind of get a little bit of a preview of it you can't really see it that well so let's hit okay and then that's it that's that looks perfect and it's parametric so if we wanted to come up here and make it 150 it scales it perfectly so let's bring that back to 100 because that'll mess up our tool paths but we can update the tool path and if you want to go down of a deeper cut you can do that as well but you have to tie the thin extrude that we did to it which i didn't do but you could do that and that's it you can kind of 3d print this or mill it out like we did and that's really awesome but then you might be wondering well how did you do this how did you do the circular thing it's pretty much the same kind of sketch workflow but instead of doing extrudes i'm actually doing an emboss so i basically created a sketch projection of the kumiko kind of frame and then just use that to be my to be my sketch for for wrapping it around the cylinder now the emboss only works with cylinders it's not going to work with a revolve shape or a sweep shape or a lofted shape it only works with cylinders so just that's the one caveat with the emboss the emboss tool but check out my emboss video for like for more a full breakdown on how to use the emboss tool but that's basically what i'm doing here it's a deboss which is cutting in and then i kind of use the circular pattern to wrap it around the cylinder and then i shell it out so that's how i created the internal shape there but yeah i will share these files as a downloadable link so look in the description of this video and you can grab these you can make a parametric i think it is yeah it's parametric for me so it'll be parametric for you too so you can change this out i have this fitted inside one of my ikea planners which looks really cool you can you know make a drain hole or a saucer for it and all that stuff but you now know how to break down the kumiko asanoja pattern into its individual elements and then like just go to town with like what kind of project you want to do whether it's like a milled project or see a 3d printed thing um it's so fun to kind of create these geometric patterns you know inspired by the kumiko woodworking techniques so that's going to do it for this tutorial i hope you folks enjoyed it let me know if you make a cool kumiko inspired project that's going to do it for this one folks i'll see you next time but until then remember to make a great day bye folks
