Fusion 360 - Projecting Sketch To Surface - Hairbrush Model Part 2

Hello guys welcome to part two of our fusion 360 tutorial on creating a model of a hair brush, so in part one we did 3d sketching and surfaces and creating that surface into an actual, solid body. That'S what we were left with so i'll. Just take you back through that, so we had a 3d sketch from that 3d sketch we created the surface. The surface has no thickness to it. You can 3d print that, for example, and then from that we were able to create a body actually had some thickness to it. So what we're going to be doing in this part is creating a sketch that we can project to a surface. So the first thing we're going to need to do is to create an offset plane or offset from the bottom here and we'll go up. It doesn't really matter about how much, but we'll say, 20 as long as it's above the top of our object here. Okay, now we'll create a sketch on this plane, so we'll be hovering above our object and we will project and we'll project by body, so that gives us this round ring there. So this is an exact kind of outline of what's below. Okay, now we're going to choose our offset tool and we'll offset by five and then we'll offset by 10., we'll offset by 15. we'll offset by 20. and then finally we're going to draw a center line. I'M just going to draw like so and then we're going to constrain that it's midpoint to there. Okay. So now i can stretch this out to the lens that we want it to be. I go finish sketch. Okay, so now we have a sketch of an outline. You may be wondering exactly what this is all will be made clear later on, but this is going to be the paths that we're going to use to arrange the bristles of our hairbrush. So what we're going to need to do is project these onto the surface. Below okay, so the way we do, that is, we are going to have to create a new sketch, so we'll create a new sketch and it can be on pretty much any plane that we want, but um we're going to select the bottom plane. For this. We'Re still in our sketch sorry, i need to finish our first sketch. First there we go okay, all right so now we'll create a new sketch and we'll put it on this bottom plane here all right. So now you can see, we've got two sketches visible. We'Ve got our sketch that we just drew, which is the geometry that we wish to project, and then we have our new sketch, which at the moment is blank. So what we will do is we'll go to create project, and this will be project the surface. Instead of our usual project, this projector surface that we're going to choose the faces that we're going to project to will be these faces below us and the curves that we're going to project will be all of these. Above here now, it's giving us a warning here. Have certain selected curves that couldn't be projected sure why but some of the curves it's saying cannot be projected these outside ones. Here we don't need. We only need to project these inner ones, see if it still gives us the error. Okay, so those are ones that we wish to project and we're going to project along a vector rather than projecting to the closest point. So presenting to the closest point will not always get us to the place where we want to be. But if we project along a vector it will just go straight down. However, projecting along a vector is giving us a problem, select the vector we're going to project on straight down. There we go okay, so now we have our projected geometries, you can see it's gone straight down from where we were before and basically draped it over our object below now, uh we've got a couple of curves missing, select and also the center line. Okay. So that's everything selected. We go to okay and finish sketch. Now, if we hide our previous one, you'll see that now we have drawn out projected onto our surface the sketch that we had before okay. So these are going to form the paths that we're going to use later on for forming our bristles of the brush okay. But before we get into that we're just going to model some more parts of the brush. Okay, so uh we will use the um sketch tool again create a new one, this time we'll do it on this geometry. Here again, we will project and we'll protect the body we'll check this okay and then we'll offset this by about three millimeters. Okay, now we can finish the sketch and we can extrude this down, we're not going to cut we're going to join or actually create a new body from this. Rather than joining it and we'll come down seven millimeters, okay. So now we've got two bodies here: okay, so this lower body and the upper body. So these are two different parts of our brush. This lower body now we're going to add some fillet to the edges and i'm going to actually extrude this in one millimeter again on these edges. Here, we'll add a point to a point. One two yeah point: two radius there. Okay now we'll also add a radius on the bottom, like so, okay, now we're still going to need a handle for this brush. Okay, but this is our starting point of the main body of the brush, so we're going to need to add a handle to it, and we may also want to add some um shape to the bottom rather like we did on the top part. So we'll create a sketch. This will be a 3d sketch first thing we'll do is we'll project. This then we'll create a three-point arc. So just like what we did in the first tutorial, but it won't come up quite as much just a little bit then we'll create our three-point arc again. The other direction there again we're going to break these the separate parts and put in our cross lines. So we can also break the projected piece. Okay, so now we will go to our surfaces create a patch again, then we will mirror this and we'll stitch those together. Then we mirror again mirror plane will be here, okay, and we can stitch this together. Also, okay, now we're going to do the same before in part one of the tutorial we will thicken. This object create a new body from it. Okay, then this body i'm going to move down one millimeter, then we will combine these two bodies together. Now we have our two separate sections of our brush here, so we can now name these so um we'll call this the sponge, that's going to be the part that the brushes are inserted to, and we call this part here, the body okay. So we still don't have a handle yet and we'll cover the handle in the next part of this tutorial, and what i'm going to do now, just to finish this off is give this some color. So our sponge here and we'll work more on the actual materials later on, but for now just to give it some look, choose a fabric for here and we'll make this gray fabric and then plastic for the brush body i'll make it a red plastic. Now we'll do some work on the actual materials later on um, changing the colors and so on, but for now that's as far as we're going to go in this part of the tutorial change, our display settings i'll just show you what it looks like if it's Um just shaded only so there we go so obviously we have a little bit of issue with these joints here and the textures but, as i say, we'll cover texturing later on, but that is our basic shape in the next part of the tutorial. We will be looking at adding a modeling on the handle and then finally, we'll be going back to our projected geometry here to create the actual brushes, the cones of the of the hair brush. So thanks for tuning in and i'll see you in the next part of our tutorials
