Intersection

Menu: Geometry->Edit→Intersection

Using this option, the intersection of many geometrical entities can be performed.

• Lines: This option lets you select several lines for which GiD then tries to find as many intersection points as possible. Lines are divided where applicable.

The 'No Divide Lines' option creates an intersection point but does not modify the lines.

• Surface-2 points: You need to select one surface and two points that lie approximately over it. GiD calculates the line intersection between the surface and a plane defined by the two given points and the average normal to the surface of these points.

Note: Planar surfaces cannot be used with this option.
Note: See Point in line, Point in surface which can be used to define the points.

• Surface-lines: You need to select one NURBS surface and several lines. GiD then calculates the intersection between the surface and the lines. Lines will be divided at the intersection point.

The 'No Divide Lines' option creates the intersection point but does not modify the lines.
The Extend/Divide lines option extends the lines until they reach the surface.

• Surfaces: This command creates the intersection lines between several surfaces.

The 'No Divide Lines' option creates the intersection point but does not split the contour lines.
By default the surfaces are divided, unless the No divide surface option is selected.
