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:  


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.  
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: Three dimension mode options are available: 

Trimming Both Lines


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. 



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


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

Dimensioning the Edge Intersection PointYou can create several chamfers just by multiselecting 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 NonPerpendicular Lines 

Between Crossing Lines 

Between NonIntersecting 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
