Solidworks Parting Line draft

The workflow for Parting Line draft is as follows: 1. Select a direction of pull — this can be an edge, axis, sketch line, plane, or planar face. Set the direction to positive or negative along the selected direction. 2. Select the parting lines — these are edges of the faces you want to draft. The parting line edges remain stationary while the rest of the face tilts. Along with the parting line selection, you may also need to use the Other Face option. Every edge is adjacent to two different faces. The Draft feature automatically selects the face it thinks you want to draft, but it does not always get it right. Other Face enables you to intervene when the automatic selection is incorrect. 3. Set the draft angle remember that you can use the Allow Reduced Angle option if you need to. Step draft The most complex of the types of draft that SolidWorks creates is the Step draft. Step draft is used on non-planar parting lines when Parting Line draft would cause the drafted faces to be split into multiple faces. The word “step” can be said to refer to two different aspects of this feature. First, the parting line can said to be a “stepped” parting line because it is non-planar and at two different levels. Second, the draft actually steps out the drafted face at one level of the parting line. Step draft keeps the face intact and introduces an intentional mismatch ledge (step) at the parting line. Figure 32.12 shows the difference between Parting Line draft and Step draft on a simplified part. The image on the left is the Parting Line draft. The middle image is Step draft where a ledge is only created on one side of the parting line. The image to the right is essentially double Step draft, where the total step size is minimized by distributing it across both sides of the stepped parting line.
