Click Pulling Direction
Pulling Direction toolbar. The dialog box is displayed.
The compass is snapped automatically onto the current axis system.
Pick the part in the viewer.
The visible part of the part becomes green (Cavity,
oriented in the pulling direction, up to 1 degree).
If you turn it
over you will see that the underside is red (Core, oriented
away from the pulling direction).
Areas that cannot be associated to
either Core or Cavity areas are shown in either
pink (for virtually vertical surfaces, as here) or blue (Other,
i.e. undecided cases). You can see that two faces of the hole are in
After having defined the main pulling direction, you will
transfer the two other faces of the hole and the surrounding front
face to Other.
Select the Locked check box to lock the pulling
Select the Local Transfer check box and select
Other in the list.
Select the faces as shown in blue.
Explode has become available to visually spread
apart Core and Cavity areas.
Enter 70 mm in the field below to define the spread.
In the exploded view, you can see the Core side in green, the
Cavity side in red and the Other side in blue.
Note that the Other area has not moved: Explode
takes only the Core side and the Cavity side into

Edit Main Pulling
Direction calls up the main pulling direction so that you can
edit the parameters.
Pulling Direction allows you to update the parameters (for
instance the scaling ratio) after modification.
When there are several axis systems, you can make one of
them the current one using
Set as current axis system.
In the case of large models, some faces may not be seen and, as a result,
can cause holes to appear in the core or cavity side.
This occurs when the relative size of a face is small with respect to the
You can avoid this problem by changing the Pixel Culling value to 0
in Tools > Options > General > Display so that all the
faces in the model are used in the pulling direction computation.
