When you add chamfers and fillets to a composite solid, the chamfers and fillets become sub-objects for that composite solid. As I mentioned in a previous post, you can select sub-objects using the CTRL key. As you pass the cursor over a composite solid, the chamfers and fillets highlight. You can then click to select them just as you can with solid primitive sub-objects. Unlike solid primitive sub-objects, chamfers and fillets don’t have object grips. However, they do have object properties. For example, if I press the CTRL key and select the large fillet on the air hockey paddle, the Radius property is displayed in the Properties palette. When I enter a different value, the model dynamically updates to reflect the change. After experimenting with different sizes, I’ll set the radius back to 3.
If, when you used the Fillet tool, you selected multiple edges to fillet, all of the fillets created by that single operation are treated as one object. For example, I applied the 1 unit fillet to two edges at the same time. When I pass the cursor over either fillet (with the CTRL key pressed), both are highlighted. If I change the Radius value in the Properties window, both fillets are updated.
You can edit 3D chamfers in a similar way. When you CTRL-select a chamfer, the Properties palette displays the First Distance and Second Distance.
In addition to changing the fillet and chamfer values you can also remove fillets and chamfers. For example, I decided I don’t want a chamfer on the bottom of the air hockey paddle. I can use CTRL-select to select the chamfer and then use the Erase tool to remove it.
