Surface Creation when Extending Face by Line Law

To create a surface, do the following:

1)Select a face relative to whose normals the incline of the surface being built will be set.

2)Select the directrix. It can be a path, a route, a profile, an edge or a sequence of elements. The element selected should be closed. The sequence can contain both smoothly joint and not smoothly joint elements. The sequence can form a closed contour. The directrix should entirely lie within the specified face.

3)Select a variant to continue from the list. The Extension parameter determines the direction of surface creation.

Outside. If a solid body face is selected, the surface will be created at the external side of the body. If a surface face is selected, the direction is determined by the normal to the face. In this case the direction of surface creation coincides with the normal direction. If the opposite direction is required, select the Inside variant.

Inside. If a solid body face is selected, the surface will be created at the internal side of the body. If a surface face is selected, the direction is determined by the normal to the face. In this case the direction of surface creation is opposite to the normal direction. If the opposite direction is required, select the Outside variant.

Symmetric. The surface is symmetrical to the face selected.

Different. This variant makes it possible to set different values for the surface height in inwards and outwards directions.

4)Set the surface height. Specify the distance from the directrix to the surface edge in the Height field. In case the Different extension variant is selected, two input fields are available: Height (outside) and Height (inside) which determine height in corresponding directions.

5)Set the incline angle of the surface being created to the normals of the selected face: enter the value in the Angle field. By default the value equals to zero. This means that the surface being created is located along the normal to the selected face. If the value is 90°, the surface being created is tangent to the face selected. In case it is necessary to change the incline direction to the opposite one, set the flag in the Mirror option on.

6)Select fracture processing variant from the list in case the contour being created has fractures.

Split. Every section of a broken directrix forms its own face not connected with the faces formed by other sections.

Extend. Faces formed by a broken directrix are extended to intersection or vice versa cut along the intersection line.

Round. Faces formed by a broken directrix are joined by the surface formed by the circular arc of a variable radius. This option is only available when there is a breakage between the surface faces. In case of their intersection the option cannot be used.

7)Finish the command by means of .
