3D Modeling 10: FILLET in 3D

The easiest command in 3D solid modeling is FILLET command. It is so easy that, in practice, it is much more easier than rounding in 2D. Now, let’s have a look at an example.
Fig.1
Select the solid entity that you can see in the figure from one of its edges where you want to make rounding .

Command: f FILLET Current settings: Mode = TRIM, Radius = 0.0 Select first object or [Undo/Polyline/Radius/Trim/Multiple]: Select first object or [Undo/Polyline/Radius/Trim/Multiple]: Enter fillet radius: 3 Select an edge or [Chain/Radius]:

As soon as you select a 3D solid entity, AutoCAD perceives this immediately and prompts you to enter a radius and select the edges. First, the edge that you have selected at the beginning (1) must still be selected. Then, select the edges (2) and (3) along the edge that you would like to round. As soon as you press enter, you will notice that the rounding has been made along the edges that you have selected (Fig. 2).

This simple operation also has an option: ‘Chain’. If the edges that you would like to select are making up a plane and are following each other, then you can use ‘Chain’ option to select all

As I told you, it is even easier than
