Rounding edges

Use the PullTool used to distort or deform geometry. Use the Pull tool to offset, extrude, revolve, sweep, draft, and blend faces; or to round, chamfer, or extrude edges. When converting a sketch to 3D, pulling a line creates a surface and pulling a surface creates a solid. tool's RoundRounded corner at the intersection of two lines or edges. Round refers to an exterior corner; an interior corner is known as a fillet. Rounds and fillets are both called rounds. See Fillet, Constant-radius round, Variable-radius round. option to round the edges of any solid. You can also round an inside or outside corner of a surface. To create a rounded face between two faces, see Rounding between faces and surfaces.

Rounds are recognized as a face type, with their own options in the Properties panel. You can change the RoundRounded corner at the intersection of two lines or edges.

You can change a constant- or variable-radius round with the PullTool used to distort or deform geometry.

To round an edge

1. Click the PullTool used to distort or deform geometry. Use the Pull tool to offset, extrude, revolve, sweep, draft, and blend faces; or to round, chamfer, or extrude edges.

2. Select the edge or edges you want to round. Double-click to select a tangent chain.

   You can also select the vertex of an inside or an outside corner of a surface.

3. Select the RoundRounded corner at the intersection of two lines or edges. Round refers to an exterior corner; an interior corner is known as a fillet. Rounds and fillets are both called rounds. See Fillet, Constant-radius round, Variable-radius round. option in the Options panelArea of the user interface that enables you to modify functions specific to tools. or from the mini-toolbar. This option is automatically selected for edges that can be rounded.

4. Click and drag the edge in the direction of the PullTool used to distort or deform geometry. Use the Pull tool to offset, extrude, revolve, sweep, draft, and blend faces; or to round, chamfer, or extrude edges. When converting a sketch to 3D, pulling a line creates a surface and pulling a surface creates a solid. arrow.

   To dimension the round, press the Spacebar, type the radius, and press Enter.

   When you pull an edge to create a round, the PullTool used to distort or deform geometry. Use the Pull tool to offset, extrude, revolve, sweep, draft, and blend faces; or to round, chamfer, or extrude edges. When converting a sketch to 3D, pulling a line creates a surface and pulling a surface creates a solid. tool determines whether it should be a constant radius or a variable radius round based on the geometry.

   Once you create a round, pulling an adjacent face also pulls the round.

   When you round more than one edge at the same time, and one or more of the rounds cannot be created, only the successful rounds are created.

The face hidden by the round is remembered, so that if you fill the round it can be displayed. If you move a round, the face hidden by it is also moved.

 

 

Examples

Pulling edges on geometry that automatically determines rounds will be variable radius.

When creating surface-to-surface rounds, the expansion direction depends on the order in which you select the edges. In the example above, the rounds expand toward the left because the upper edge was selected first.

To create a full round by selecting edges

1. Click the PullTool used to distort or deform geometry. Use the Pull tool to offset, extrude, revolve, sweep, draft, and blend faces; or to round, chamfer, or extrude edges. When converting a sketch to 3D, pulling a line creates a surface and pulling a surface creates a solid. tool.

2. Select the two edges on opposite sides of the face you want to become a full round, or select the circular edge on the end of a cylinder.

   You can select more than one pair of edges, and create full rounds between the pairs.

When converting a sketch to 3D, pulling a line creates a surface and pulling a surface creates a solid. the edges down so they are just rounded.

4. Slowly pull the mouse in the opposite direction, until the faces are no longer round, and continue pulling until the full round appears.

To convert a constant-radius round to a variable-radius round

1. Click the PullTool used to distort or deform geometry. Use the Pull tool to offset, extrude, revolve, sweep, draft, and blend faces; or to round, chamfer, or extrude edges. When converting a sketch to 3D, pulling a line creates a surface and pulling a surface creates a solid. tool.

To edit a variable radius round

• Click the PullTool used to distort or deform geometry. Use the Pull tool to offset, extrude, revolve, sweep, draft, and blend faces; or to round, chamfer, or extrude edges. When converting a sketch to 3D, pulling a line creates a surface and pulling a surface creates a solid. arrow on an end of the round face and drag toward or away from the face to adjust the radius at the edge of the round.

• Click the PullTool used to distort or deform geometry. Use the Pull tool to offset, extrude, revolve, sweep, draft, and blend faces; or to round, chamfer, or extrude edges. When converting a sketch to 3D, pulling a line creates a surface and pulling a surface creates a solid. arrow pointing toward the center of the face and drag it along the face (or enter a length or percent) to set another point where you can adjust the round's radius.

• Hold Ctrl and drag to copy a control point.

• Press Tab to switch among and edit the dimensions by typing a number.

• Two rounds that intersect at a shared edge can be made variable together by selecting the shared sharp edge for modification. Both rounds become variable at that point. They can be made variable independently by selecting the sharp end edge that is not shared by the rounds.

In the PullTool used to distort or deform geometry. Use the Pull tool to offset, extrude, revolve, sweep, draft, and blend faces; or to round, chamfer, or extrude edges. When converting a sketch to 3D, pulling a line creates a surface and pulling a surface creates a solid. tool, when you select an edge of a constant radius round, the Smooth option becomes enabled if the geometry allows it. When checked, the transition between radius at each end of the round will vary smoothly instead of linearly. Once set, the Smooth option remains set for subsequent rounds until you change it.
