Draft: Pulling Axis System
Pulling axis direction that can be defined:
The pulling axis direction can be locked once you have set the axis system so as to avoid unintentional modifications that can be made when you are moving the compass.
You can use the Reverse button to reverse the pulling direction.
Lock the Pulling axis direction before using:
Select this check box to display the normal to the face
and the angle value between the pulling direction and the normal when you
move the mouse pointer over the surface.
Defines the minimum un-molding angle between the surface and the main pulling direction.
They are the Core side (displayed in red), the Cavity side (displayed in green), Other (displayed in blue) and No Draft (displayed in pink). Other indicates surfaces that are neither core or cavity and that will be dealt with later. No Draft is made of the surfaces that are vertical with respect to the draft angle.
If even only one facet a face is not clearly
either core or cavity, the whole face will be considered to be "other" and
displayed in blue. You can use the
Display option to solve this problem.
We have selected the Facet display option:
It is clear that a little amount of facets is considered as belonging to
the Core and not to the Cavity.
We have unselected the Facet display, selected Facets to
ignore and defined the percentage of facets to ignore with the slider.
Undercut zones are recognized via the facettisation of the part.
Select Undercut to take account of hidden faces for a given pulling direction.
The orientation of the facets normals may also lead to "inverted" core and cavity areas for a given pulling direction, i.e. the expected Core area is recognized as a Cavity area, and vice-versa.
Click Switch to invert those areas directly, without inverting the orientation of the normals nor the pulling direction.
Transfers one face of the part to one of the three areas to extract (Core, Cavity, Other).
Local transfer is available in exploded view.
By default, Faces display is active, i.e. the faces of the part are displayed.
The definition of the core and the cavity is based on a facetisation of the faces. The deviation of the normal to a facet with the pulling direction defines whether the facet belongs to the core or the cavity. If one facet in a face does not clearly belong to the core or the cavity, the whole face will be considered to be "Other" and displayed in blue. In this case, it is interesting to know how all the facets of the face behave, to decide to split the face, or to transfer it to the core or the cavity side.
Displays the facets on a blue face so that you can find which one(s) is (are) not compatible with the rest of the face and solve the problem.
Displays the graphic visualizations of the Core area and of the Cavity area apart from each other, along the current pulling direction.
