Rib

Calling the command:

A rib is an element that is obtained by extension of a contour in the given direction until intersection occurs with the faces of the initial body.

Ribs can be created on the basis of closed as well as open contours. The result of execution of this operation is a solid body obtained with a Boolean operation of union of created rib with the initial body.

 

The user specifies direction of extension of the initial contour and its thickness. After selection of several contours a grid of ribs can be created. In this case the thickness for several objects is specified immediately for the entire grid.

Contour may consist of several parts. In this case one direction to solid body is specified for all parts of the contour.

It is not necessary to limit rib contour with solid body walls. In most cases system can automatically determine the boundaries of the created edge. On the picture below the rib is limited with planes of the solid body faces.

1. Solid body faces

2. Rib contour

Note that if borders can’t be automatically determined the construction of the rib will not be possible.

Creation of rib

To create the operation, it is required to execute the following sequence of actions:

1.Select the source body;

2.Select forming contour;

3.Select direction of extrusion of the rib;

4.Specify thickness of rib;

5.Specify additional capabilities of the operation (not a necessary step);

6.Confirm creation of operation.
