Patchwork

Menu access: Shape | Other shapes | Patchwork

Description:

Allows you creating a surface or solid using a net of crossing curves (minimum of 4).

Curves will be automatically divided into two categories: guide curves and section curves.

General philosophy:

Select the curves you want to use to create the patchwork shape.

Available option(s):

The option  Mode= SMOOTH  or  MULTIFACES  allows you to choose the way the shape is constructed.

With the smooth mode there is neither edges no discontinuity problems on the interpolation curves.

When curves are closed, you can choose the type of shape to create with the option  Type= SOLID  or  SURFACE TYPE . When you choose the solid type, the created shape will be solid if possible. If not, not any message will appear.

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

You can change the intersection tolerance for the detection of the intersection between the guide curves and the section curves and take them in consideration.

Example(s):

The blue curves are considered as guide curves and the red ones as section curves.

Specific point(s):

 Curves must be intersecting.

 The patchwork accepts intersecting curves, but limits the created shape to the intersection.

 Each section curve must intersect only one time each director curve.

 Curves can be 3D or free form (non-planar).

 In case of the section curves or guide curves are closed, you can obtain a solid. Faces are added at the ends to get a solid shape. The added faces must be planar faces.

All curves of same type (section curves or guide curves) must be all open or all closed and cannot intersect each other within the same type.

 In case of closed section/guide curves, you need to have a minimum 3 section/guide curves.

Available modification(s):

By using the icon , you can:

• Change the creation mode (smooth or multi-faces).

• Change the type (solid or surface type).

• Change the tolerance.
