CHAMFERS

T-FLEX CAD allows creating chamfers and various fillets without any preparatory constructions. The
existing elements of the drawing are modified, and new ones created in the process.
Chamfer Creation
To create a chamfer, use the command “FE: Create Chamfer”. The command is called in one of the
following ways:
Keyboard Textual Menu Icon
“Draw|Chamfer”
To create a chamfer, you need to do several subsequent steps:
1. Select the chamfer type and set its parameters.
2. Select the defining nodes or graphic lines.
Upon calling the command, a dialog box is displayed on the screen for defining the necessary parameters and
selecting the type of the chamfer being created. (By default, the dialog box is instantly launched by the
system).
Upon confirming the selections with the graphic button [OK], the following actions can be performed:
Set command options
Select Node
Select Graphic line
Exit command
T-FLEX CAD supports three main techniques of creating chamfers:
• Chamfer creation by selecting the node through which the hatch contour is passing. The chamfer is
displayed in this case as a construction entity.
• Chamfer creation by selecting the node through which two graphic lines are passing. The chamfer is
displayed in this case as a graphic entity.
• Chamfer creation by selecting graphic lines. The chamfer is displayed in this case as a graphic entity.
Note that the corner chamfer can be created based on straight graphic lines only.
If the selected elements are not appropriate for the selected chamfer type or were selected incorrectly, then a
dialog box is displayed with an appropriate error message.
Chamfer Creation by a Node through which the Hatch Contour is Passing
This technique is intended mainly for creating chamfers at the drafting stage when the graphic lines are not
created yet. A chamfer created in this way is drawn as a construction entity. Later, you will have to apply
graphic lines over this chamfer manually. On the other hand, if the graphic lines were created before
introducing the chamfer, then the chamfer will be displayed as a graphic entity. This technique is intended
