For creating the weld of this kind, three guides must be specified. The body of the weld, triangular in cross-section, is formed in such a way that its lateral edges coincide with the guides.
For the guide, the user can select edges, 3D paths, 3D profiles, etc. It is also possible to define the guides by a group of 3D elements (edges, paths, etc.) on condition that all selected elements of one guide form a continuous sequence.
The length of the created weld is equal to the length of the first guide. In cases where it is desirable to create the weld longer than the guide, the user can specify the magnitude of extensions at the ends of the guide. The body of the weld will be elongated (by a parallel shift of the end sections) by a specified extension length.
For the weld by three guides it is possible to specify the contour type (flush, convex, concave) for the side lying between the first and the second guides.
