Draft tapers faces using a specified angle to selected faces in the model. One application is to make a molded part easier to remove from the mold. You can insert a draft in an existing part or draft while extruding a feature. You can apply draft to solid or surface models.

How do you calculate draft angle?

How to Calculate Draft Angle For Plastic Parts. The general rule is to add a minimum of 1° of draft for every inch of depth in a mold cavity. You could add up to 2° but, aside from depth, other factors influence the size and effectiveness of a draft angle.

Why is draft analysis important?

With draft analysis, you can verify draft angles, examine angle changes within a face, as well as locate parting lines, injection, and ejection surfaces in parts.

What does minus draft mean?

In situations where clearance is required, such as an as-cast bolt hole, material is taken away to create draft (minus draft). Dimension is held at or closest to the parting line and material is taken away for draft. Outside dimensions get smaller, inside dimensions get larger.

What does negative draft mean?

A negative draft means the angle of the face, with respect to the direction of the pull, is less than the negative reference angle. Requires Draft. Displays any faces that require correction. These are faces with an angle greater than the negative reference angle, and less than the positive reference angle.
