Parting Line Draft

The parting line option lets you draft surfaces around a parting line. The parting line can be non-planar. In a draft using a parting line, you can also include a Step draft.

To draft on a parting line, you can first divide the faces to be drafted by inserting a split line, or you can use an existing model edge. Then you specify the direction of pull, or the side of the parting line from which material is removed.

You can check the draft angles on your model using the draft analysis tool. Draft analysis creates a color-coded rendition of the model faces based on the angle and the direction of pull criteria that you specify.

To insert a draft angle parting line:

  1. Sketch the part to be drafted.

  2. Insert a split line curve, if desired.

  3. Click Draft on the Features toolbar or click Insert, Features, Draft.

  4. Under Type of Draft, select Parting Line.

    Under some conditions, select the Allow reduced angle check box.

  5. Under Draft Angle, enter the Draft angle .

  1. Under Direction of Pull, select an edge or face in the graphics area to indicate the direction of pull.

  2. Under Parting Lines , select the parting lines in the graphics area.

    Note the arrow direction. To specify a different draft direction for each segment of the parting line, click the name of the edge in the Parting Lines box, and click Other Face.
