3D solids have gotten an update in AutoCAD 2011. Specifically we have a new Fillet and Chamfer tool that allow us to preview our changes and make revisions dynamically on screen. In this lesson we are going to look at the new Solid Fillet and Chamfer tools. Since we are going to be working in 3D, take a look at my Workspace menu. Notice I'm using the 3D Modeling workspace. This gives me access to all of the 3D modeling tools. The drawing I have is of a screwdriver. All of this geometry was created using 3D solids, and before I go any further, I'm going to move up to the View panel, we'll open up the Visual Styles menu, and I'm going to select X-ray.
This gives me a much better view of all of my geometry. Since these entities are solids, I am going to be using the solid editing tools. So I'm going to open up the Solid tab, and the tools we are going to be looking at are on the Solid Editing panel. If I open up this menu, we can see the new Fillet Edge and Chamfer Edge tools. I'm going to hit Escape to close this menu, and let's orbit the part around. I am going to zoom in just a little bit. The first thing I'd like to do is add a fillet to this end of the screwdriver.
To do that I'll launch the Fillet Edge command, and then I'll right click and select radius, and I am going to use radius of 0.25 and I'll let Enter. I will then select the edge. Notice that I get a nice preview of that radius on screen. At this point I can hit Enter, and if I like the radius I can hit Enter again to accept it or I can select radius from this menu and enter a new value, maybe 0.15. Once again I have another opportunity to change if I wish, or I can click this direct manipulation grip and I can drag my fillet visually on screen.
I am going to drag this and place it right about here. When I am finished, I'll hit the Enter key. At any point if I want to change the geometry of this fillet, I can hold my Control key, select the fillet, then I'll click this grip. This brings up my Direct Manipulation tool, and if I click this triangle, I can drag to change my fillet radius or I can enter a new value. When I am finished, I'll hit Escape. Let's orbit the part around. I'm going to hold my shift key in the scroll wheel to do that.
And I'll pan this down, because I would like to add some fillets to the blade end of the screwdriver. I want to zoom in a little bit closer. Watch this. If I roll the wheel forward on my mouse, I end up chewing right through my part. I actually went past it. Let me roll the wheel back, so we can see the part again. This actually is a product of our 3D Perspective view. Sometimes we get a little bit too much zoom than what we need. To fix this I'm going to right click on my view cube and set this to Parallel. Now when you zoom, it acts a lot more like what you would expect.
This time I would like to fillet these two edges. Once again I'll launch the Fillet Edge tool. I'm going to right click and set my radius. I'm going to enter a radius of .02 this time. I will select this edge and this one, and I'll hit Enter. I am doing this to show you that since these fillets were created at the same time, time, AutoCAD treats them as still they're related. If I click my direct manipulation grip and drag this, notice I'm changing the radius of both fillets.
When I am finished with my changes I'll hit Enter. Likewise, if I want to update these later, I can hit my Control key and select the fillet. They're both still related. In fact, if I wanted to, I could remove them both by hitting the Delete key on my keyboard. Lets back up a little bit. We'll orbit the part around again. I'm going to right-click. Let's set this back to Perspective. This time let's add a chamfer to this edge.
I'll go back up to Solid Editing, we'll open up the menu, and I'll select the Chamfer Edge tool. I'll then right click and select Distance, and then I will enter my two distances. I am going to use a value of .25 for distance number one and .25 for distance two. Then I'll select my edge. Once again we can see a nice preview. That chamfer is a little bigger than what I need, so I'm going to hit Enter and from here I could set a new distance, or if I orbit this a little bit, we can see that we have the direct manipulation grips.
I actually have two, one for each value. If I click this guy, I can adjust distance one. If I click this guy, I can adjust distance two. When editing your 3D geometry it's a good idea to keep your eye open for these specialized grips. They are used for more than just fillets and chamfers, and they can be one of the fastest ways to edit your geometry. Now I like the way this looks so I'm going to hit Enter, and as an example, if we wanted to edit this later, we can always hold Control and click chamfer, click this tool and once again we have access to our direct manipulation grips.
Now I like this one so I am going to hit Escape to leave it the way it is, and to finish the screwdriver I'd like to turn on a layer. So I am going to select the Home tab. Let's come all the way down to the end, open up the Layers panel. I'll open the layer control. and we'll turn on the Remove Layer. This layer contains some geometry that I would like to remove from the volume of the handle. To remove this I'm going to go back to the Solid tab. I'll launch the Subtract tool. I will then select the handle.
That's what I want to subtract from, and I'll hit Enter, and then I will select the objects I would like to subtract and hit Enter. Those have now been removed from the volume of handle and our screwdriver is finished. The new Solid Fillet and Chamfer tools take the guesswork out of creating conceptual designs. By making the changes visual, it's even easier to mold and shape your models on screen.
