Join Surface

InsertSurfaceJoin

The Join Surface command enables you to join two or more surfaces to form a single surface.
Three different union modes can be chosen in the Autosmooth drop-down list.

Not enabled — Using this method, the selected surfaces are simply joined.
- If they have no shared boundary, the proper control points are moved so that the two surfaces are joined. The resulting surface will have an invisible edge at the shared boundary.
- If they already have a shared boundary they are joined at the shared boundary, which becomes an edge. The shape of the surface is not modified and the resulting surface has a real edge at the shared boundary.
Fixed boundary — The surfaces are joined in such a way that their shape is modified to obtain slope continuity. The resulting surface has an invisible edge at the shared boundary.
Movable boundary — The surfaces are joined in such a way that the border between one surface and the other has a uniform curvature. The resulting surface has an invisible edge at the shared boundary.

Conversion to NURBS
When a selected surface is not a NURBS, you will be asked to confirm whether you want to convert it into a NURBS (unless you have deselected the Ask before converting check box).

You can specify what to do with the original surfaces. In the Base Entities drop-down list, select one of the following:

Delete	To remove the original surfaces from the model. Only the resulting joined surface will be available.
Hide	To hide the original surfaces, though keeping them in the model.
Keep	To keep the original surfaces, leaving them visible.

Note
Please note that the Delete and Hide options do not apply to faces of solids and skins. An appropriate warning is displayed in such cases.

Finally, take into account that the command applies only to not trimmed surfaces. Selection of trimmed surfaces is not enabled.
