Joint Flanges and Gap |

Parameters of the joint flanges and the gap are set in the Borders section. It is available for shell rings based on closed sketches.

Joint flanges of the shell ring
Select a method for creating joint flanges using the Joint Flanges group of buttons. The following options are available.
Perpendicular to the sheet surface: the edge surface is perpendicular to the surface of the shell ring along the entire gap.
When the gap is placed on a flat portion, the joint edges are flat (Fig. a). On a non-flat portion, the joint edges can be both flat (Fig. b) and ruled (Fig. c).
Parallel to each other: the edges are trimmed by planes parallel to the planes, which in turn are perpendicular to the contour of the flange at the point of the gap.

Construction of joint edges by method Perpendicular to sheet surface
|
A shell ring with an open sketch (sketches) has joint flanges always perpendicular to the sheet surface. |
A gap value is set in the Gap field. Only positive values are allowed. The maximum admissible value of the gap depends on its location in the shell ring: the gap should not go beyond the inner wall (see Figure).
