Already up and running? This course is the next step in building your Autodesk Inventor skillset. Author John Helfen takes you through the interface and key processes of this parametric design system, including sketching, part modeling, assemblies, and drawings. Each process works in conjunction with the rest, allowing you to create parts and assemblies and document them in a way that they can be manufactured. Learn how to set up your project file; create and modify geometry; create extrusions, sweeps, and lofts; build parts with placed features and patterns of features; and create iParts and iFeatures. John also covers assembly visualization techniques, drawing views, and balloons and parts lists.
The course was created and produced by John Helfen. We're honored to host this training in our library.
Now that we've learned how to create rectangular patterns, and we've even looked at how to build intelligence into those patterns; I want to take a minute to look at one of the more unique features within a rectangular pattern. I'm also going to touch on the curve length option, which we looked at briefly in the previous movies, but this is a perfect example of where you would use the curve length option. I'm going to begin by going to the pattern panel and selecting rectangular pattern. I'll select the hole, or Extrusion2, as the feature we want to pattern, and I'll go to the Direction option.
As I mentioned in the previous movie, you can use model edges to define the direction of your pattern, or you can use sketch geometry. And you don't have to use just straight sketch geometry; you can actually use splines and arts as well. So what you can see here is while I am in this direction pattern, I can simply select the edge defined in this sketch as the direction for this rectangular pattern. So while it's called rectangular pattern, you can use just a single edge that's curved to essentially create a pattern along the path.
I'll set my instances to five, and you'll see that I start out at a distance of one inch, between hole one and hole two. Another inch between hole two and hole three, and so on. But here's an option where a curve length is a perfect result. We can start with the first hole on the start point, and the final hole on the end point And evenly distribute the remaining three items along that curve. By selecting OK here you can see that we have created a hole pattern that actually is on a curved arc.
I'm going to go ahead and turn on my shaded edges by using the navigation bar and selecting shaded with edges. If you don't have that option, you can use this triangle to select a visual styles to enable it. But with that on, you can now see that if I hover over this sketch that was driving that, Sketch3, those holes perfectly follow that path. So again, one of the more unique items within the rectangular pattern command is the fact that it can create patterns along a path, and this is the example of how you could do that.
