Chamfer

The Fillet and Chamfer commands are quite similar in their application. The Chamfer options are described below.

Chamfer The Chamfer option can be used in two different ways. The two options available from the Modify menu and Icon are Chamfer Distance + Distance and Chamfer Distance + Angle. These are explained below.

Chamfer Distance + Distance (Shortcut: CHAMFER)

This option allows the user to create a chamfered corner where the two lines of the junction meet. This option will create the chamfer along 2 specified dimensions and will trim the corner accordingly if required.

• In Opus draw a Rectangle or Square similar to the one shown below.

  

• From the menus select Modify > Chamfer > Distance + Distance or select the Chamfer - Distance + Distance Icon from the toolbar or type CHAMFER in the program.
• A prompt requesting the Distance along the First Line, Distance along the Second Line and whether the corner is to be Trimmed or not will appear . Enter the information you require and press the enter key to end.

  

• The prompt will change and ask for the user to select the First Element on the Junction.

  

• Once selected the prompt will ask for the Second Element on the junction.

  

• The Chamfer will be created with the relevant sizes trimmed from each element at the junction.

  

• The program will then run in a cycle, asking for the First Element again, until the user right clicks the mouse or clicks escape.
  Note: If different sizes are required on different junctions it is necessary to perform this operation separately for each of the different Chamfers.

Chamfer Distance + Angle (CHAMFERANGLE) This option is similar to the Chamfer in that it will trim back the corner junction a specified distance. The difference between this one and the Chamfer Distance + Distance is that it only requires one Distance and creates the chamfer at the specified angle.

• In Opus draw a square or rectangle similar to the one below.

  

• From the Menus select Modify > Chamfer > Distance + Angle or select the Chamfer- Distance + Angle Icon or type CHAMFERANGLE in the program.
• The prompt will be displayed, asking the user to select the Distance along the First Line, the Angle from the First Element to the Second Element and whether the Junction has to be trimmed or not.

  

• Once this information has been entered the prompt will change and ask the user to select the First Element, this is the Element that will get the Distance applied and from where the Angle to the Second Element will derive.

  

  The user will then get prompted to select the Second Element

  

• The Chamfer will the be applied to the part.

  

• The program will then run in a cycle, asking for the First Element again, until the user right clicks the mouse or clicks escape.
  Note: If different sizes are required on different junctions it is necessary to perform this operation separately for each of the different Chamfers.
