Modifying the continuity between two sets of surfaces

After starting the Advanced Surface Continuity command, proceed as follows (please note that you can follow this step-by-step example by loading file: "SurfaceAdvancedContinuity.e3").

1	Select the chain of surface borders to be modified. Finally, end selection (by right-clicking and selecting Continue or by clicking on Reference Curves or Surface Boundaries).
2	Select the reference boundaries/curves.   Appropriate handles are available to move both the endpoints of the contour to be modified and the ones of the reference contour. Instead of using the handles, you can type the contour parameter value into the corresponding boxes (U0, U1). The Continuity drop-down lists enable you to select the type of continuity to be applied along the selected contours (reference and to be modified) and along the contour marked as Preserving. The available types are the following (for a detailed description of the continuity types, see Continuity Types): Free — no continuity condition will be applied (available only along the contour marked as Preserving) Position Tangency Curvature
3	Set the continuity condition along the reference contour.
4	Set the continuity condition along the contour to be preserved (marked as Preserving)
5	Click the Preview ( ) button to get a preview of the result. The Bulge factor of the resulting surfaces can be set through the appropriate drop-down list under More Options. The higher the bulge factor, the more rounded the shape of the resulting surfaces (see also "Examples of the Bulge parameter"). Number of discontinuities Please note that when the active parts of the selected contours do not have the same number of tangency discontinuities, a warning is displayed.
6	Click or to confirm your selections and create the surfaces (the resulting surfaces shown in the illustration below are visible after hiding the original ones). Click to discard your changes.
