Define boundary conditions

Identify supports

Supports are vertices of the FormDiagram where reaction forces can be present. If there already are vertices of the Pattern which was fixed during the modification of the Pattern, they will be automatically defined as supports. Please refer to the first tutorial example to see how the vertices of a Pattern can be selected or unselected as supports.

Update boundaries

In order to update the unsupported boundaries of the Pattern, the desired sag to span ratio is calculated. With the desired sag value for all or some of the unsupported boundaries, force density method is used to relax the Pattern to the specific desired sag value.

Please refer to the first tutorial example to see how curvature can be introduced to unsupported boundaries of a Pattern.
