Draw Directions

Draw directions are used to ensure that a design space can be physically manufactured using a specific process such as casting, stamping, or extrusion.

Draw directions are a type of shape control. If you intend for a part to be manufactured by casting it or stamping it, the optimized shape must allow the two halves of the mold or the stamping dies to separate after the part is formed. Negative draft angles must be avoided. You can generate shapes that can be molded or stamped by indicating a draw direction, which is the plane where the two halves of the mold are pulled apart.

Only one type of draw direction can be applied to a design space. Draw directions are valid for optimization but not analysis.
