Creating Drafts from Reflect Lines  

 

 

 This task shows you how to draft a face by using reflect lines as neutral lines from which the resulting faces will be generated. In this scenario, you will also trim the material to be created by defining a parting element.
Open the Draft3.CATPart document.

  1. Click Draft Reflect Line .
    The Draft Reflect Line Definition dialog box is displayed and an arrow appears, indicating the default pulling direction.

Pulling Direction

  • Contextual commands creating the pulling directions you need are available from the Selection field:
    • Create Line: For more information, see Creating Lines.
    • Create Plane: see Creating Planes.
    • X Axis: the X axis of the current coordinate system origin (0,0,0) becomes the direction.
    • Y Axis: the Y axis of the current coordinate system origin (0,0,0) becomes the direction.
    • Z Axis: the Z axis of the current coordinate system origin (0,0,0) becomes the direction.

    If you create any of these elements, the application then displays the corresponding icon next to the Selection field. Clicking this icon enables you to edit the element.

  1. Select the cylinder.
    The application detects one reflect line and displays it in pink. This line is used to support the drafted faces.
The icon now available after the Faces to draft field lets you edit the list of the faces to be drafted. For more information about that capability, refer to Editing a List of Elements.

  1. Enter an angle value in the Angle field. For example, enter 11. The reflect line is moved accordingly.

  2. Click Preview to get an idea of what the draft will look like.

  3. Click More>> to expand the dialog box.

Parting Element

  1. Check the Define parting element option and select plane zx as the parting element.
Contextual commands creating the parting elements you need are available from the Selection field:
  • Create Plane: for more information, see Creating Planes
  • XY Plane: the XY plane of the current coordinate system origin (0,0,0) becomes the parting element.
  • YZ Plane: the YZ plane of the current coordinate system origin (0,0,0) becomes the parting element.
  • ZX Plane: the ZX plane of the current coordinate system origin (0,0,0) becomes the parting element.
  • Create Join: joins surfaces or curves. See Joining Surfaces or Curves.
  • Create Extrapol: extrapolates surface boundaries or curves. See Extrapolating Surfaces and Extrapolating Curves.

If you create any of these elements, the application then displays the corresponding icon next to the Selection field. Clicking this icon enables you to edit the element.

Limiting Elements

The Limiting Element(s) option limits the face to be drafted by selecting one or more faces or planes that intersect it completely. To know how to use this option, see Basic Draft.

Contextual commands creating the limiting elements you need are available from the Limiting Element(s) field:

  • Create Plane: for more information, see Creating Planes
  • XY Plane: the XY plane of the current coordinate system origin (0,0,0) becomes the limiting element.
  • YZ Plane: the YZ plane of the current coordinate system origin (0,0,0) becomes the limiting element.
  • ZX Plane: the ZX plane of the current coordinate system origin (0,0,0) becomes the limiting element.

If you create any of these elements, the application then displays the corresponding icon next to the Limiting Element(s) field. Clicking this icon enables you to edit the element.

  1. Click OK to create the draft.

Using the command described in this task, you can draft faces after filleting edges, as illustrated in the example below:

The application detects the reflect line on the selected fillet.

 The face is drafted.
