Connect Untrimmed Surfaces

3-D FFS > Process > Connect untrimmed surfaces

Use this function to connect 2 untrimmed surfaces continuously.

1. Identify the border of the 2 freeform surfaces you want to connect.
2. Specify whether you want to change only the second surface or both surfaces.
3. Select the connecting method:

• Continuous,
• Tangent-continuous or
• Curvature-continuous.

The two freeform surfaces shown below are to be connected with each other:

Left: Change of 2nd surface, Method: Continuous; Right: Change of both surfaces, Method: Continuous

Left: Change of 2nd surface, Method: Curvature-continuous; Right: Change of both surfaces, Method: Curvature-continuous

The enlarged image shows that the curvature-continuous method produces rounder transitions than the tangent-continuous method.
