Learn how to create extrude features, revolve features, and a pattern of features. Discover how to apply fillets and chamfers, and create a 3D thread feature.
- [Instructor] Parametric solid models are a collection of sketched features like extruded and revolved profiles and placed features like holes and fillers. Let's review some of these tools by completing a design that's already been started. In Fusion 360, I have the beginning of my spanner design. In the timeline, you'll see we have three sketches and you can see sketches are visible on the model as well. We'll begin by creating an extrusion to create an access port for a socket wrench. I'll start the extrude tool and select the profile.
Having the profile I'll go all the way through the model. I'd like to create another access port for the socket but at a different angle. So I'll return and turn my sketch back on, then come under the Construction pull-down and create a work axis. Based on the center point of the sketch, normal to the face, so that I can create a circular pattern of the original extrusion, make sure my pattern type is set to feature and select the extrusion from the timeline.
Then for the axis, I'll select the newly-created work axis in the middle of the first extrusion, set the number of units and set the angle to be 45 so that it gives us more options for putting a wrench on the spanner. I'll create another work axis under the construction pull-down, but this time I'll place it at the center of the curve. With this axis in place, in existing model edges I can create a plane between two edges.
The reason I need this plane is I want to create a termination for a revolved surface that doesn't exist without this plane. So starting the revolve tool, I'll select my profile, select the axis that I created and then set the termination to be this plane, making sure that it's a joining geometry to the current model. I can easily turn the visibility of all this construction geometry off by using the light bulb icon in the browser. Now to add a few placed features, I'll start the fill-it tool, either from the Modify pull-down, selecting F or by using press-pull.
I can even select through the model by clicking and waiting a moment and selecting the edge. Simply drag the radius out and again using the marking menu to repeat the process with three more edges. To finish the design, I use the Modify pull-down to select the chamfer tool and add a chamfer to the edge of my part. Parametric solid modeling is the primary approach that has popularized 3D mechanical CAD, but it's not the only approach available in Fusion 360.
Next, we'll look at direct modeling and later, free-form modeling.
