Contour (Plot)
Create a contour plot.
Syntax
model.result(<pgtag>).create(<ftag>,"Contour");
model.result(<pgtag>).feature(<ftag>).set(property, <value>);
model.result(<pgtag>).feature(<ftag>).run();
Description
 model.result(<pgtag>).create(<ftag>,"Contour") creates a contour plot feature named <ftag> belonging to the plot group <pgtag>. Contour plots are available in 2D and 3D plot groups. Contour lines are colored by their level. Add a color expression attribute to color them by an arbitrary expression.
The following properties are available:

Fill surfaces outside of contour levels if contourtype is filled.
inheritcolor
Boolean

Boolean
true
If inheritplot is not none: Determines if the deformation scale is inherited.

How to specify contour levels.
levelrounding
Boolean
true
Round the contour level values, if levelmethod is set to number.

refine
nonnegative integer
1
The element refinement to use, if resolution is set to manual. Bear in mind that this is the refinement used for the base dataset, so the number of elements in the model can increase radically if the plot uses, for example, a revolve dataset.
resolution
norefine | coarse | normal | fine | finer | extrafine | custom
normal
Controls the plot’s resolution. A finer setting results in a higher resolution by modifying the internally computed default refinement. Use custom to enter your own refinement in the refine property.
