Modify Surface
Advanced Continuity
The Advanced Surface Continuity command enables you to modify continuity between surfaces and sets of surfaces (with consecutive boundaries). The result of the command is a new set of surfaces matching the chosen continuity conditions (while the original ones will still be there).
Continuity can be applied to match a curve or a target shape, which can be defined using the Mode drop-down list.
After selecting a set of consecutive surface boundaries (i.e.: a chain of surface boundaries) to be modified (Boundaries to Be Modified) and a chain of surface boundaries and/or of 3D curve entities (from now on, the term contour will be used in the place of chain of boundaries/curves) to be used as the reference contour (Reference Curves or Surface Boundaries), the program determines and highlights the ones to be preserved (Preserving).
You will be able to set the continuity conditions between the two contours and also along the contour marked as Preserving, which can be positional, tangency or curvature continuity (and also "free", in the case of the contour to be preserved). As to the meaning of continuity types, see " Continuity Types". Please note that if the reference contains a curve entity (i.e.: not a surface boundary), only positional continuity can be applied.
You can also change the portions of both the contours to modify and of the reference one by supplying the desired initial and final parameter values (U0, U1), or by dragging the corresponding appropriate handles.
You can model the shape of the resulting surface by setting the Bulge factor under More Options.
A preview mechanism is always available, enabling you to interactively assess the result you are obtaining.
Associative Mode The surfaces created using this command can be associative: associative surfaces are Skins, that is open solids, retaining a link to the base entities, so that if you modify the base entities the surfaces will be modified accordingly; they have a history and are displayed in the Model Structure. See "Associative Surfaces (Skins) for details. |
Surface Continuity command Please note that Positional and Tangent continuity between couples of single surfaces can also be applied using the Surface Continuity command. |
