Fillet / Chamfer

Introduction

This topic will explain the Fillet / Chamfer function, will explain where to find the function, and explain the options found in it. This topic will also explain creation with quick steps, examples, and provide links to related topics.

The Fillet / Chamfer function

The Arc Fillet function creates an arc, of a defined radius value, tangent to two selected entities. The Chamfer function creates a line between two entities using an angle and/or distance.

To open  Fillet / Chamfer, do one of the following:

 

  • In the Corners group, of the Create 2D ribbon, click  Fillet.

  • In the Corners group, of the Create 2D ribbon, click  Chamfer.

 

 

The parameters display in the Data Entry Manager.

The Data Entry Parameters

Type

Fillet - selecting this occupational enable the creation of fillets.

Chamfer - selecting this occupational enable the creation of chamfers.

Picking Method

Between 2 Entities - requires clicking one entity and then the other to create the fillet or chamfer between the two entities.

Single Corner Click - a single click where two entities meet creates the fillet or chamfer.

 

Chains - allows you to select an entire chain of entities to apply the fillet or chamfer to all possible locations on the chain.With the Chains option chosen, the Selected Geometry list becomes available.

 

Selected Geometry

 

 

(Delete) - removes the highlighted item from the Selected Geometry list.

(Delete All) - removes all entities from the Selected Geometry list.

The list will display all entities currently selected for the function.

Parameters

Fillet

The available Parameters vary based on the Type chosen.Listed below are the Parameters for the Fillet option.

    • Radius - sets the distance from the center of the arc to the circumference of the arc.

    • Trim

Select the check box to have the selected wireframe entities trimmed when creating the arc.

Clear the check box to create the arc without trimming the selected entities.

 

Chamfer

The available Parameters vary based on the Type chosen. Listed below are the Parameters for the Chamfer option.

 

    • Angle - sets the angle of the chamfer from the selected entities.

    • Distance 1 - sets the distance from the edge of the (first) selected entity to start the chamfer.

    • Distance 2 - sets the distance from the edge of the (second) selected entity to start the chamfer.

 

Chamfer Method

There are three methods to select from when creating chamfers. The selected option determines which parameters become available.

 

    • Angle & Distance 1 - uses the Angle and Distance 1 values to create the chamfer.

    • Angle & Distance 2 - uses the Angle and Distance 2 values to create the chamfer.

    • Distance 1 & Distance 2 - uses the Distance 1 and Distance 2 values to create the chamfer.

 

  • OK - creates the fillet or chamfer when using the Chain picking method.
  • Cancel - closes the function.
