The direction the part is ejected from the mold is called the pull direction. This direction is used to determine the draft angle, undercuts, and mold cost.
The pull direction is determined automatically as follows:
- The principle axes are examined, and the axis with the fewest undercuts is used. If there are no undercuts on any axis, or if all axes have significant undercuts, the second method is adopted.
- The bounding box for the part is examined. The bounding box is the smallest box in the XYZ planes that contain the model.
The pull direction is perpendicular to the side of the bounding box with the largest area. If all the sides have the same area, the third method is adopted.
- The default Z axis is used.
Attention: If you are working in the standalone product, you can
specify the pull direction, manually, from the ribbon.
