Creating Precise Offset Planes, Notches, and Fillets in Fusion Modeling

Now let's start adding the details to our rail. First we need, you guessed it, a construction plane. We'll go to Construct menu.

We want Offset Plane. Now we want to click the plane that's right in the center of our model here. We'll click right in the center.

And we can offset that plane. I want to pull it back. We're getting negative numbers again.

And I want to pull it back right to the face of the rail. And we know that is 30. So 30 millimeters is right at the face of that rail.

Once we've got that, we can click OK. And there is that plane. Now let's give it a name.

It's called Plane 3 right now. Let's call it Side of Rail. OK.

So there it is, Side of Rail. And I want nothing selected. So I'm going to click out in space.

Nothing is selected. And we can start another sketch. So go to Create menu, Create Sketch.

And we can pick that Side of Rail plane. We're drawing right here on the side of the rail. The first thing we want is a notch right here at the front.

So I'm going to start the Line command. And zoom right in to the bottom of that rail. And I'll click.

And I'll go up. And I want to go up 11. Hit ENTER.

There it is. Now I want a second line. I'll start in the same place.

And I will go to the left now, 15 millimeters. Enter. I've simply created two lines there.

And now I want to connect their ends in a diagonal. So I'll start the Line command again. Click once.

Click twice. And I've got a triangle right there. So that's perfect.

Now let's roll over to the back. And do something very similar. I'll start in the very back point.

So I'll click right there. And I'm going to go up a little bit. This time, 8 millimeters.

So I'll go 8. Enter. And I'll start another line. And this time, I will start at that same lower left point and go to the right.

And I'm going to go to the right a much longer distance now, 50. Enter. OK, so I've got two lines of the triangle.

Now I can make the connection from end to end. There we go. Another triangle.

That looks good. Those will be my two, we'll call them notches. We'll click Finish Sketch.

And now we need to use those sketches to pull out our notches. And to do that, we'll start with the Create Extrude or E on the keyboard. And I can select my two profiles.

I'll click the first one and the second one. They're both part of Sketch 3 right now. And now I get that arrow.

It's right here. And I can drag it all the way through. And Fusion's smart.

It knows that I want to cut, or it's assuming that. And I can pull it visually, the 60 millimeters, or type that in. And once I'm happy with that, let's verify it did it on the back as well.

That looks good. We'll click OK. OK, we've got our two notches.

Now we need some fillets to round things out. We will go to the Modify and we'll look for a fillet. And we want to select our fillet areas.

We can keep adding them in here. Let's just start clicking. We can click Edges, Faces, or Features.

We did Faces last time. This time we'll do Edges. We zoom in pretty tight.

We can start clicking Edges, which are these lines. So the first two lines on one side of the rail and the second two small lines on the other side of the rail. Now we'll orbit this around to the back.

And we also want to grab these back lines as well. So that makes for five edges. And one more would be six.

Now we want to add in our radius for that fillet, which is 10. We'll type that in here. And we'll notice it fillets those right away.

If we roll up to the front, we'll notice those also now have fillets. And we can click OK. So there are our fillets and notches looking really good.
