Use the Draft page to add a draft angle to a vertical pass.
Draft — Select this option to enter a draft angle.
From — Select the location of the toolpath relative to the curve:
— The draft angle is taken from the top cut. 
— The draft angle is taken from the bottom cut. 
Angle — Enter the angle of the draft, relative to the tool axis.
Area Filter — Select to ignore areas smaller than the Threshold value.
- Threshold (Tool Diameter Units) — Enter the size against which all areas are compared. The value entered represents the ratio between the tool diameter and the longest principal axis of each individual area. For example, a value of 2.0 means that the length of the longest principal axis of an area is compared against twice the tool diameter.
