Creating Chamfers

This task shows how to create a chamfer between two lines trimming either all, the first or none of the elements, and more precisely using one of the following chamfer definitions:
 
  • Angle/Length (Hypotenuse)
  • Length1/Angle
  • Length1/Length2
 
  This page deals with the following information to create chamfer:
You can create chamfers between any type of curves (lines, splines, arcs and so forth). Even if the curves are not consecutive, the chamfer will be created.
Open the Chamfer.CATPart document.

  1. Click Chamfer .

The possible chamfer options are displayed in the Sketch tools toolbar. The Trim All Elements option is selected by default.

Six profile mode options are available:

  • Trim All Elements:

  • Trim The First Element:

  • No Trim:

  • Standard Lines Trim:

  • Construction Lines Trim:

  • Construction Lines No Trim:

Three dimension mode options are available:

  • Angle and Hypotenuse:

  • First and Second Length:

  • Angle and First Length:

 

Trimming Both Lines

  1. Select the Trim All Elements option .

  1. Select the first line and the second line.
    The selected lines are highlighted.
 
 

The second line is also highlighted, and the two elements are connected by a line representing the chamfer which moves as you move the cursor. This lets you vary the dimensions of the chamfer whose values appear in the Sketch tools toolbar.
 

  1. Click to indicate where to create the chamfer.
    The chamfer with both elements trimmed is created.
 

Provided the Dimensional Constraint option command is active, the constraints will be created between what we call in the scenarios below the old intersection point and new end points of the lines.
 
 

Trimming the First Line

  1. Select the Trim The First Element option .

  1. Select the first line and the second line.
    The chamfer with one element trimmed is created.
 
 
 

No Trimming

  1. Select the No Trim option .

  1. Select the first line and the second line.

The chamfer with no element trimmed is created and the original lines are kept.
 
 
 

Trimming Both Lines Until their Intersection

  1. Select the Standard Lines Trim option .

  1. Select the first line and the second line.
    The chamfer is created and the two lines are trimmed up to the two lines intersection.
 
 
 

Trimming Both Lines and Creating Construction Lines Until their Intersection

  1. Select the Construction Lines Trim option .

  1. Select the first line and the second line.

  • The chamfer is created and the two lines are trimmed.

  • Two new lines are created between the intersection and the trimmed extremity of the lines, and set as construction lines.
 
 
 

Trimming Both Lines and Creating Construction Lines

  1. Select the Construction Lines No Trim option .

  1. Select the first line and the second line.

  • The chamfer is created and the two lines are trimmed.

  • Two new lines are created between the previous extremities and the trimmed extremity of the lines, and set as construction lines.
 
 
 

Dimensioning the Edge Intersection Point

You can create several chamfers just by multi-selecting for example, the rectangle endpoints and entering the definition parameters in order to define these chamfers (Sketch tools toolbar). Four chamfers are created at the same time with the same parameter values.

Using the Length1/Length2 Option

 
 

Between Perpendicular Lines
 
 

Between Non-Perpendicular Lines

 
 

Between Crossing Lines
 
 

Between Non-Intersecting Lines
 
  Note: if the lines are parallels, the extremity points are used to compute the lengths because the virtual intersecting point does not exist.

Between Intersecting Curves
 
 

Between Non-Intersecting Curves
 
 

Using the Length1/Angle Option

 
 

Between Non-Perpendicular Lines
 
 

Between Non-Intersecting Curves
