Adding concentric holes

“

- [Instructor] Placing holes is going to be one of the most common activities you do as a designer in AutDesk Inventor. On the screen you can see holes complete.ipt and over the next several movies we'll go ahead and create each of these types of holes on this model. Here you can see holes start.ipt which is the same block with none of the holes in it. To create a hole we need to launch the hole command. We can do that from the 3D model tab under the modify panel here on the left, or we can right click in the graphics window and select hole from the marking menu. When you do that you'll notice that the holes panel appears on the screen. Now it's important to know because this is a panel there are several ways you can dock it. And the first one is to leave it floating, undocked. You could also bump it up against the browser and locate it there. Because it's a panel you could even dock it inside the browser, if you wish. You could put it above the browser, but in this case I like it on the right because it gives us the most visibility of the model along with the browser and the hole panel. I'm going to go ahead and shrink that a little bit so that we don't use up as much space. And now we can go ahead and begin placing our first hole. Now you'll notice at the top of the hole panel the placement option is red, indicating that we need to define a placement for our first hole. We want to hover over the top of this top boss, and left click, and you'll see a preview appears with some heads up display. Now that we have the hole positioned on the plane we want you'll also notice that we have a little orange dot above the center point. That means that this hole is active so anything we select from this point forward will help us position this hole on that face. In this case we want a concentric hole so we're going to want to either select the concentric face here, the edge, or the concentric face or edge on the top. Now if we selected the one on the bottom, it would work, it would give us a concentric hole. But, if our design ever changed and this boss on the top moved around on this platform, the hole would no longer be concentric to this top boss. So we want to make sure we select a circular reference either the edge or the face here so that we can lock that into position on the top of the boss. You'll notice that the orange dot turned red indicating that it's properly positioned. Now we can look through the hole panel to decide what other option we'd want to change for this hole. Just below the placement option are the different types of holes we can create. You can have simple holes, clearance holes, tapped holes, even tapered tapped holes. You can also change the type of seat that each of these holes has. You could select a counterboard, spotface, or countersync. In this case we're not going to use a seat. We want a straight through hole. So what we're going to do now is look at the size and termination options. So under termination we have the ability to set this hole to a specific distance to create a blind hole. We can go through the entire model or to a specific face. We're going to let it set to through all. And finally, we can either change the diameter here, or we can use the orange circle that shows up here to drag in the heads up display. I'm going to go ahead and set that to .75 and I'm going to select okay to create that hole.
