To Create a Constant-Angle Tangent Draft Inside a Draft Surface
1. Click Model > Surfaces > Blend Tangent to Surfaces. The Tangent Surface dialog box opens.
2. To create a tangent draft with a constant draft angle inside the drafted surface, click .
3. Specify the draft direction by selecting one of the following:
One Sided—The draft is created only on one side of the reference curve.
Two Sided—The draft is created on both sides of the reference curve.
4. Specify the pull direction.
5. Click the References tab, click under Draft Line Selection and select the reference curve. The reference curve can be any chain of edges or curves (such as a draft line). The reference curve must lie on a surface of the reference part.
6. In the Angle box, type the value for the draft angle.
7. In the Radius box, type the value for the radius of the fillet that connects the draft surfaces with the adjacent surfaces of the reference part.
8. Click to preview the tangent draft geometry. If required, you can change the draft geometry by specifying the Spine Curves or Closing Surfaces on the Options tab. You can also edit the reference curve by using the Curves tab.
9. When satisfied with the feature geometry, click to close the dialog box and create the feature.
