Description

Contours are the curves produced when surfaces and solid entities are intersected with a plane which is normal to one of the axis directions. Intersections in the three axis directions (XY (Waterlines), YZ (Stations) and XZ (Buttocks) can be set up individually from Contours dialog (Tools -> Contours...). Intersection curves through other planes, such as diagonals, can be created using the Plane entity and turning on Surface Intersections.

Show/Hide/Toggle Contours

If an entity supports contours it will be available as a display option. Toggling the display options turn on and off the display of the contour lines. Contours lines can only be display if contour planes have been defined and intersect with the entity.

Extract Contours

If an surface or solid entity is presently displaying contours, they can be extracted as a PolylineList entity to obtain a section based representation of the surface.
