This task shows you how to perform a draft
operation on two opposite sides of the part using one pulling direction.
What makes the Advanced Draft capability very productive is that
it also makes it possible to adjust the resulting faces on the chosen
parting element, as illustrated in this scenario.
Instead of using Advanced Draft to
created both side draft features, we recommend you use Draft Both
Sides which offers a more easy-to-use dialog box. More specifically,
it provides helping images which dynamically reflects the geometry you
select while designing. For more information, see

-
Click Advanced Draft
in the Advanced Draft toolbar
.
In case the icon is not displayed in the workbench, to
access it select View > Toolbars > Advanced Draft then display
the Advanced Draft sub-toolbar.
The Draft Definition (Advanced) dialog box is
displayed as well as an arrow indicating the default pulling direction
(xy plane) in the geometry area.
-
Specify that you wish to draft two faces from their
reflect lines by clicking both icons as shown:
The Faces to draft options are no longer
available. Now, three draft modes are proposed.
Draft Modes
The three draft modes available are:
- Driving/driven: the angle value you specify for
one face affects the angle value of the second face.
- Independent: you specify two angle values that
apply to both faces respectively.
- Fitted: you specify a minimum angle value for one
side and the application ensures that both sides are adjusted
onto the parting element.

-
Set Fitted.
1st Side
-
To define the first draft angle value, enter 3deg as the
minimum draft angle value.
Neutral Element
-
The Neutral Element frame is reserved for the
face you wish to draft. Click No selection from the combo list
and select the face as shown:
The application is going to detect the reflect line from this
neutral face, and therefore the face that will be affected by the
draft operation.
Pulling Direction
In the Pulling Direction frame, you can
notice that the Selection field indicates that a pulling
direction has been defined by default as indicated by the arrow in the
geometry area. If you wish to change this pulling direction, you
just need to click the field and select the element of your choice as
the new pulling direction.
Parting Element
-
Click the Parting Element tab to define the
parting element.
-
Check Use parting element and select
Extrude.2 (the blue surface) as the parting element.
-
Enter 0.1mm, if not already set, in the Parting Line
Adjustment field.
This option adjusts the smoothness of the transition zone on the draft
surface. A transition zone occurs when a neutral element that was driving
becomes driven, or vice versa. A zero parting line adjustment would yield
a sharp edge on the draft surface. Usually, the default value (0.1mm) is
most of the time efficient.
2nd Side
-
To define the other side to be drafted, click the
2nd Side tab.
Neutral Element
-
In the Neutral Element frame, click No
Selection from the combo list and select the face as shown:
Note that the reflect line of the face you selected as
the first side is now displayed in pink.
-
Click OK to confirm. The part now looks like
this:
Taking a closer look at the result, you can notice that both sides are
adjusted onto Extrude.2.
