How to Create a CAD Model from a Photo in Fusion 360! FF96

hi folks let's take this 3d printed knife handle and less model it in fusion 360 using a pretty cool trick welcome to other fusion Friday [Music] [Music] how do we do this as an entrepreneur I need to be able to build stuff an experiment in prototype and my belief is fail fast and fail cheap so if I need to get a 3d model of this made pretty quickly and I don't have the 3d model I've only got the part take a quick picture of it create a new component call it a knife handle insert attached canvas terrible name great feature what face are we going to put it on I'll pick between the green and the red which is the XY plane click here on the mountain to pick my image knife handle and for now we're just going to click OK so one of the things I like about this is it's not the pet perfect picture I didn't take my time to set up really really good lighting it does help to have high contrast and obviously to be aligned overhead from it next we grab our trusty dial calipers and pick two points I'm going to pick the outside most points it's just the easiest measurement to grab and I get 3.5 to expand the knife handle expand canvases right to click and choose calibrate take the leftmost point representing where the calipers would have touched and pick the out in the side most point over here as well 3.5 - we did this way back when fitting a mag well into a stock and we got within four thousandths of an inch pretty cool right see for circle what plane do we want to sketch on this plane right here we're gonna start sketching so my rule of thumb when I reverse engineer things is I tend not to worry too much about the hole locations precisely if I can recreate the whole stack of holes in other words if I'm off a little one way or the other from the part doesn't always matter since in this case we would be Deary creating everything else around it kind of center over here you'll see you do get a lot of perspective distortion from that angle the through holes are about 187 316 so different dimension 0.75 here we'll say equal I'll click this one and that one let's move it over about there now those two I want to stay in that location I'm gonna click on the white dot hold down control key click on the next white dot and I'm now gonna click fix it will turn them green and I can no longer move them to sketch the outside of this s4 keyboard shortcut KRC for arc three-point arc pick a point and I try to look for kind of change in direction so we'll see if we can get one from here to here that matches one two three there we go my screen recording software doesn't seem to like doing this all at once so that looks good now we've got a little bit of a problem here I can tell so I'm actually just gonna start a arc from here come back there we go something like that I don't like that corner we'll come back to it click there might be able to get all the way through here maybe not now it's a different radius see that it looks great and then it doesn't work so here so you can either try to drag this back which worked here or you can just delete that arc and start over I'm actually going to move it back to this point here right click hold down and swipe up or repeat the same motion so in other words that lets you do a new three-point arc click on that arc click on here in the end so yeah there's the prop we need to we're not gonna be able to do that last little tail part so see how it move the first one let's say I didn't want to do that if I like this first one again I'm going to click once HitFix now when I create my second arc I can't it won't accidentally move that one like so and keep going away all around here the fewer the arcs the better and I'm no industrial designer but one trick is keep your arcs tangent to each other makes the part look a lot better most of the time so what do I mean by that like click I'll hide my canvas real quick if I click tangent I keep this arc tangent to that arc very subtle change it helps a lot that's a problem you keep it tangent you keep a sweeping motion now it can be really difficult to keep the parts matching or it can go haywire like you just just saw it did right there see that that's no good obviously so that's one reason why I can really help to lock down certain segments that you think are in a really good place see that it's moving that around so let's undo some of that okay I'll keep the thing on so I don't like that there we go that's the problem that's just not gonna work so I'll just lock that one down without it being tangent now I'll create this if I can create tangency between these two there we go look at that it's actually pretty nice and it's a trade-off are we trying to match this design perfectly or are we just trying to get our own design that has a good flow to it last SARC between there and there pretty good you pull that point up just a hair pull it out a little I kind of call this freeform design you can hit D for dimension and click on an arc and actually set an actual radius interesting maybe that is a 13 inch radius regardless pretty darn close we've got some cleanup to do though first let's extrude it leaf or extrude click on it point to five let's fill it it s fil choose the 3d or solid model fill it walk around the edges and we'll say point one inches click OK now question is you want to do corner fill its or edge fill its first let's try that we can actually keep this fill up I think rewind our timeline and do again s fil and say we want to put some fill it's on the sharper corners here something like that click OK and we can then fast-forward to the end one last thing I want to show you that's kind of cool we need to counterbore these two holes if you look at the original part there are a couple counter bores we can do that all on one sketch which i think is a really elegant way to do it right click on your original sketch one edit sketch c for circle let's say they're quarter inch do the second one and make it equal the first one stop sketch so now the problem is that that counterbore extends from this top face down about 60 tooth out the sketch is on the wrong plane leaf extrude I'll click the first counterbore and this second one now change your start from the profile plane and let's change it to from object now we're able to click this top plane and now see how the arrows pointed up that means if I type a negative it's going to cut negative point oh s--- oh six to five and now we've been able to keep everything on one sketch plane keeps things cleaner it means you have to do less projections you can see your dimensions and relative sizes all on one plane and we've been able to extrude from multiple services folks hope you learned I hope you've enjoyed I'd love to hear from folks that are designers knife makers and industrial designers I'm sure there are better ways we could do this CAD whether it's like we did the video on splines or just general shapes but I got to say looks pretty good folks take care see you soon [Music] you
