Tangency control handles

Use the tangency control handles to specify the tangency condition at curve and surface boundaries. These handles provide a direct method to manipulate the shape of a surface by specifying different tangency conditions.

The BlueSurf, Bounded, Redefine, Lofted, and Keypoint Curve commands support various continuity and tangency conditions. The tangency control handles provide a common method for each of these commands to control the end conditions.

The handle has two elements:

• Tangency control handle (1) – Drop-list to control the type of tangent condition

• Tangent magnitude handle (2) – Drag handle which also supports a magnitude dynamic input box (3).

  

  

There are two tangent magnitude handle options that are available when creating and editing a bluesurf surface, loft protrusion, or keypoint curve.

• Multiple tangent magnitudes (1)

  This option exposes all magnitude handles for the section. You can edit any magnitude handle and the remaining handles are unchanged.

  

• Single tangent magnitude (2)

  This option exposes a common magnitude handle for the section. You edit a common magnitude handle and the remaining section magnitude handles have the same value.

  

You can drag the handles or type a magnitude value in the dynamic input box.
