Menu access: Shape | Other shapes | Ruled circular

Description:

Allows you to create a solid or surface shape by sweeping an arc between 3 curves.

General philosophy:

1. Select the first curve and choose its direction.

2. Select the second curve and choose its direction.

3. Select the third curve and choose its direction.

Available option(s):

 The option  Sweep synchronisation= ARC LENGTH or  PARAMETRIC allows you to choose the type of synchronization between the curves.

The option  Section curves= VISIBLE  or  HIDDEN  allows you to keep visible or not the curves after the ruled shape is created.

Example(s):

The section curves are represented in red.

Specific point(s):

The directions of both curves must be the same.

 You can elect all the curves by using an enclosing box. In this case, the curves will be used in their creation order.
